Protect and Replenish Your Garden Soil with a Cover Crop

What do you do with your garden beds after you’ve harvested the season’s fruits, vegetables, and flowers?

By: Valerie Rose, Skagit County WSU Extension Master Gardener

Don’t leave the soil exposed to winter rain and wind – protect your precious garden soil with a cover crop. Garden crops draw nutrients from the soil, and cover crops replenish these nutrients. Think of it as home-grown fertilizer.

Cover crops are sometimes known as green manures. Farmers spread composted animal manure on fields, a traditional fertilizer source, replenishing soil nutrients following the harvest. Cover crops are a green, plant-based fertilizer that feeds the soil without animal products, hence the term ‘green manure.’

Cover crops do many important jobs at once, working quietly in the soil when it’s too cold for even the heartiest gardeners to lift a trowel. They include many species of plants: grains, grasses, and legumes (beans and peas). These versatile plants can suppress weeds, retard erosion, add organic matter, and store nutrients for future plants. Organic matter builds better soil structure and fertility, increasing water retention, drainage, and aeration.

Cover crops grow food for the soil instead of ingredients for a salad. When planted in autumn, cover crops are dug into the garden bed in the spring. Once tilled back into the soil, cover crops break down, adding nutrients and organic matter, nourishing next year’s garden. They also provide necessary food for earthworms and microorganisms. Cover crop plants are genuinely masters of multi-tasking.

Many Varieties to Choose From
You have many choices of cover crop plants with differing benefits. Adding and replenishing nitrogen, an essential plant nutrient, clover is a real gift. Clovers are nitrogen-fixers; they take atmospheric nitrogen from the air through the plant leaves and convert it into a form that plants can use. These generous plants store this vital nutrient in small nodules on the roots with the help of soil bacteria called rhizobia. When the plants decay in the ground (or are tilled into the soil), the nitrogen is available to feed other plants. Gardeners should plant crimson clover from September through mid-October and till it under in the spring. Crimson clover is this gardener’s favorite cover crop; I till under most of the plants, leaving a dozen or two to flower. The glorious red blooms are a welcome food source for pollinators in the spring and make a long-lasting cut flower.

Austrian field peas are another great option. This cold-hardy overwintering pea is an excellent choice for cooler, poorly drained soils, which describes many garden beds we know. You can sow this nitrogen-fixing pea as late as the end of November. Dig the plants into the ground in late April or early May in the spring.

Clovers and peas benefit from ‘inoculation’ – coating the seeds with nitrogen-fixing bacteria before planting. Doing this increases the amount of nitrogen each plant can retain. Most seed dealers sell small packets of inoculum, which are actually bacterial spores of rhizobia.

The inoculum and seeds are an easy, inexpensive way to nourish your hungry soil.

Some Choices of “Green Manure” Cover Crops

Don’t Let Them Go To Seed
Cover crops should be tilled or dug into the soil before going to seed. Tilling or digging in is especially important when planting buckwheat, which is sown in summer. Clare Sullivan, a field crops expert for the Oregon State University Extension Service, notes, “The fast growth and dense canopy smothers annual weeds, protects the soil from erosion, and helps conserve soil moisture. The abundance of blossoms attracts pollinators and beneficial insects, and in a pinch, buckwheat can be added to a bouquet.”

Buckwheat roots loosen the topsoil while accessing phosphorus within the soil, which is then stored in the plant’s tissues. “When buckwheat residues are returned to the soil, the phosphorus becomes available for the next crop,” Sullivan said.

Cover Crops on Farms
Gardeners and farmers alike benefit from planting specific crops. Many farmers renew the health of their soil with cover crops. They may plant entire fields or in rows between orchard fruit trees. The Skagit Conservation District’s Cover Crop Grant Program helps eligible farmers purchase seed.

Farmers may plant cereal grasses like oats, barley, or rye. Rye is one of the most commonly grown cover crops on Northwest farms. This crop is vigorous, very cold-hardy, and can germinate and establish in cool weather. Rye grows rapidly in the spring, so it can become difficult to turn under by the time gardeners are ready to work their gardens. Mowing or weed whacking may be necessary before incorporating a heavy cover crop of cereal rye.

Livestock can enjoy grazing on cover crops such as triticale or winter rye. Even a variety of radish is used as a cover crop! Unlike radishes grown in vegetable gardens, the Forage radish loosens soil rather than enhancing a salad. Also known as “tillage radish,” their large roots “till” deep into the ground, naturally aerating the soil. Forage radishes also provide excellent food for wildlife.

Adding a cover crop to your garden is a small task with large benefits. “It seems really unlikely that you’re planting a seed in October that’s going to somehow magically do something good for you,” says David Kidwell-Slak, the National Plant Materials Center Manager for the National Resource Conservation Center. “[But] they provide a lot of benefits without much effort. It makes a pretty amazing addition to the garden.”

The Fig Tree-A Horticultural Challenge

Though best suited for a Mediterranean climate, figs can be successfully grown in the Pacific Northwest.

By: Sonja Nelson, Skagit County WSU Extension Master Gardener

Gardeners are adventurous folks, always on the lookout for a new and captivating plant to add interest to their gardens. One such beckoning horticultural challenge is the edible fig tree (Ficus carica). An example of a mature, edible fig can be found at the edge of the NW Fruit Garden on State Route 536 west of Mount Vernon. Located next to the Skagit County WSU Extension Master Gardener Discovery Garden, the NW Fruit Garden features over 200 fruit cultivars, including fig trees.

Although edible figs are widely grown in Europe’s warm Mediterranean basin, the climate of the Pacific Northwest is too cool for many varieties. However, the mature edible fig is part of NW Fruit’s experimental planting program to find the best fruits for growing in our area.

The fig specimen is the cultivar ‘Desert King,’ about 10 feet tall. The white bark on this multi-trunked, deciduous shrub is a pleasing contrast to its large, three-lobed, dark green leaves veined a lighter green. In July, the pear-shaped fruit is dark green (see photo), but the skin changes to greenish white when ripe.

One of the First Plants Cultivated
Each plant in our gardens has a story to tell. However, the fig tree story may be one of the most captivating. Judging from fossils found dating from 9400-9200 BC in the Jordan Valley, which today forms the border between Jordan and Israel, the fig is believed to be one of the first plants cultivated by humans, preceding the domestication of wheat, barley, and legumes by a thousand years. Figs were widespread in ancient Greece and described by Aristotle. They were also a common food source for the Romans. Rome’s first emperor, Augustus, was poisoned with figs from his garden that his wife smeared with poison. The well-known Biblical source in the Book of Genesis refers to Adam and Eve using fig leaves to cover their private parts in shame for eating the forbidden fruit. From the 15^th century, the edible fig was grown in Northern Europe and the New World. In 1769, missionaries brought the first figs to California.
The Interesting Botany of the Fig
The edible fig fruit humans consume for its delectable sweetness is produced by Ficus carica, one of over 800 fig species in the genus Ficus. The three types of edible figs are distinguished from one another by their pollination process. The type most amenable to growing in our area is the “common fig.” The fruit skin, referred to by botanists as its “syconium,” is 1-2 inches long and green in color that ripens to purple or brown. Its interior is lined with unisexual flowers that produce seeds through a process called “parthenogenesis,” a natural form of asexual reproduction. The single-seeded fruits line the inside of the syconium, producing soft, reddish flesh containing crunchy seeds.

Most varieties of figs can produce two crops a year. The first crop is called “Breba,” which bears fruit on last year’s wood, and the second is called “Main,” which bears fruit on the current year’s wood. The Puget Sound region is usually too cool to ripen the Main crop.

Fig Research and Much, Much More
Figs are among the many varieties of fruit tested for research in the NW Fruit Garden. Recently, a new row of fig trees was planted with eight fig trees, and another row will be planted soon. The group is also planning to install a protective structure to demonstrate how to cover and protect figs in winter.

NW Fruit’s search for fig tree varieties that grow well in the Northwest extends worldwide. For instance, NW Fruit volunteer and co-chair Sam Benowitz traveled to the Brittany region in northwest France to observe and get a cutting of the fig variety ‘Madeleine de deux Saisons’ to grow and test at NW Fruit. Other new varieties include: ‘Little Ruby,’ ‘Olympian,’ ‘Brown Turkey,’ ‘Nordland,’ ‘Grantham’s Royal,’ and ‘Lattarula.’ Benowitz is a longtime volunteer at NW Fruit. Sam established and owned Raintree Nursery near Morton, Washington in 1972, building it into one of the country’s leading edible fruits nurseries, prior to selling it in 2018. His enthusiasm for his work is characteristic of the garden volunteers caring for and testing the many fruit varieties.

The Western Washington Fruit Research Foundation, now called NW Fruit, was created in 1991 to help support the tree fruit research at the Washington State University (WSU) Northwestern Washington Research & Extension Center (NWREC) Fruit Horticulture Program in Mount Vernon. It is dedicated to supporting research and educating the public about the special fruit-growing conditions of the Pacific Northwest region.

The six-acre NW Fruit Garden currently has over 200 fruit cultivars growing for research and demonstration to the public.

Growing Figs in the Ground
The climate of the Pacific Northwest differs from that of the Mediterranean region, where the species Ficus Caria is native. Although our climate is sometimes compared to a Mediterranean one because of its warm, dry summers, it falls short of being ideal for many varieties of figs. Hence, Sam Benowitz traveled to France’s Brittany area to find edible fig varieties from a climate more like ours and test them at NW Fruit.

The edible fig, Ficus carica, and its varieties thrive in rich soil and a warm microclimate. The high temperatures sometimes experienced in our area should not be a problem for figs. However, in temperatures below 10 degrees F, plants may need cover. From his experience at NW Fruit, Benowitz believes the most significant shortcoming of our climate for figs is the lack of summer heat during the growing season. The program experiments on-site with techniques, such as walls that capture heat. Regular watering of the fig trees in the garden is necessary, especially as they start. An irrigation system is set to water the figs once a week throughout the summer.

The soil for in-ground figs should be slightly acidic (6.0 – 6.5). Allow spread for fibrous, shallow root systems. Do not fertilize at planting time, but mulch with compost. Training a young fig tree involves spacing the branches and forcing them to one main trunk. Figs can also be trained to an open center or vase shape, allowing good light penetration into the canopy. In training a newly planted tree, cut it to 2 to 3 feet in height, forcing lateral buds to produce new, low branches. In the following winter, select three to four main branches, cut them back to 30-36 inches, and remove the rest. Annual pruning, which should be done in the dormant season, is usually limited to cutting back the previous year’s growth. Thinning may be necessary if the canopy gets too dense. The leaf and root sap of fig trees may cause skin irritation in humans.

Growing Figs in Containers
In the Northwest, fig trees can be planted in containers in any season. Place the pot where you want it to go, preferably in full sun, and add a few inches of well-draining potting mix to the bottom. Place the tree at the same planting depth in which it was growing in the nursery pot. Then, backfill the remainder of the pot with potting mix. The fig’s root ball should be level with the soil line, but leave two inches of space between the soil and the rim of the pot to make watering easier. Add a thin layer of organic mulch around the base of the water line. Water when the top two inches of soil feels dry to the touch. Fertilize in the spring and fall with a balanced, organic fertilizer. Pruning, if necessary, should be done in winter. Ripe figs should be slightly soft and sweet smelling and begin drooping on their stems. Figs with hard necks that remain perpendicular to their stems are not yet ripe and should not be picked.

Useful Tips for Harvesting and Preserving Herbs in the Pacific Northwest

Preserving herbs can be a bit of trial and error, but the process is worth the fresh flavor and satisfaction.

By: Laura Kuhn, Skagit County WSU Extension Master Gardener

Because of their useful nature, herbs are a common addition to home gardens. The use of the term herb is often used interchangeably with spice. However, the terms herbs and spices technically refer to two different things. “Herbs” are defined as the leafy parts of plants, such as oregano, rosemary, thyme, sage, basil, and others. “Spices” typically involve the use of other plant parts such as roots, fruits, flowers, seeds, or bark. Spices include cinnamon, ginger, lavender, coriander, cumin, and many others. Both herbs and spices are used for their savory, aromatic, or medicinal qualities. This article will focus primarily on herb preservation, although many methods mentioned here can also apply to spices.

Gardeners who grow vegetables may also grow herbs for pairing in recipes later. However, some of the best pairings cannot be harvested at the same time. For example, basil can look tired by the time the tomatoes are ready to be harvested. And it is difficult to find an easy, cost-effective way to have bunches of fresh cilantro available at the same time tomatoes and peppers ripen for salsa. Preserving herbs can help to bridge these gaps.

In 2002, when faced with a huge abundance of herbs that could not all be used fresh, I bought one of the popular “As Seen On TV” food dehydrators and dried herbs to make gifts for the following holiday season. The color and flavor of home-dried herbs are superior to store-bought herbs. Since then, I have also started to grow herbs and spices to make tea.

An often-asked question is: What is the best way to preserve herbs? The answer depends on how you plan to use them. The goal is to capture the essential oils in the trichomes (fine outgrowth like hairs) on the surface or epidermal layer of the leaves. These oils have the flavor and aroma we want.

What gardeners choose to grow and preserve is most influenced by the amount of time, budget, and available space. The good news is that with a small investment in time, space, and equipment, home gardeners can achieve excellent results that rival the expensive options available.

Growing Herbs-
Herbs can grow in most garden conditions and be planted directly in the ground, in raised beds, or in containers. Vertical garden systems are a terrific way to get a lot of variety in a small space. Gardeners who are just starting herb growing should start slowly and do their research. Purchasing herb starts at a local garden center is an easy and inexpensive way to begin. However, a far greater selection of herbs are available as seeds. Once gardeners have experience, they can grow their favorites from seed and make space for annual and perennial varieties.
Harvesting Herbs-
The harvesting process is as simple as removing the right part of the plant for the intended use. For most culinary uses, the target is tender fresh leaves (i.e., oregano, thyme, and basil). In some cases, the goal is to preserve flowers for making tea (i.e., chamomile, calendula, or anise hyssop) or to harvest the plant’s mature seeds (i.e., dill or coriander). Yet other plants are used for their roots (i.e., ginger or horseradish). If growing for flowers, it is important to pick the flowers often to encourage the production of more blooms.

For leafy herbs such as basil and oregano, the best flavor comes from young leaves on stems cut before the plant goes into flower production. However, the growing season can be extended by cutting back flowering stem tops to encourage more leaf growth. When doing so, leave four to six leaves on the plant stems for re-growth. If growing for seed, keep the flowers on the plants and wait until the seeds are fully mature. Root harvests take a longer time commitment and can require waiting for several growing seasons to achieve a decent harvest.

Organization is important during the harvesting process. It is best to harvest all of one specific plant at a time, making the cleaning and preservation process easier by avoiding the time-consuming task of separating during the cleaning process. For harvesting, no special tools are needed. Most herbs are tender enough to harvest by hand pinching or using scissors. Small clippers with short-tipped blades are best for harvesting small leaves or stems. Digging roots is a careful process. It is important to provide wide enough margins to avoid shovel damage to the roots.

Preserving Herbs –
After harvesting, the herbs require cleaning before preserving. Most herbs can be immersed in cool water to clean off the leaves (stem and all). Use paper towels, a drying rack on a work surface, or a salad spinner to get as much moisture off as possible. Avoid crushing the leaves unless the herbs are chopped before preserving them. Chives can be washed and cut into small pieces with scissors by holding a bunch of stems and cutting them as a group before preserving them.

The preservation method should strive to achieve the best quality for the intended use. Scientific research has been conducted on various methods of preservation. The winning method for drying herbs is freeze drying because it preserves essential oils, aroma, and color best. However, the cost of such a system for most home gardeners is not reasonable. Therefore, the most common methods involve dehydration (using heat) or drying (using air), which results in a shelf-stable product that can be used year-round, or by freezing.

Humidity levels in the Pacific Northwest, particularly western Washington, are a challenge to herb preservation and storage. Humidity levels should be 45-55 percent for proper drying and to avoid mold. Even during our drier summer months, average outdoor humidity levels are more than 60 percent. The water content in the herbs being dried is also a consideration. The more tender herbs, such as basil, tarragon, oregano, lemon balm, and mints, tend to have a higher water content. On the other hand, sage, thyme, parsley, and rosemary tend to be more “woody” and have a lower water content. Taking this into account before picking a preservation method increases the chances of success.

Drying with Air–
Drying with air is by far the easiest method of preserving herbs but difficult to master successfully given Pacific Northwest humidity levels. Mold can form on plants, or the dried product will be limp and discolored. Make small bunches of plant stems, wrap with butcher’s twine, and hang the bunches up. The drying area will need to have good ventilation (an oscillating fan works great). Avoid exposure to light during drying as it will affect the color. A barometer or humidity gauge helps decide if drying is possible. Woody plants such as rosemary and sage are best for this process due to humidity levels. The amount of time needed to dry the plants and crush the leaves will vary based on weather and drying conditions. Checking plants often is the best way to gauge if they are ready.

Dehydrating with Heat–
The National Center for Home Food Preservation recommends drying herbs at 95 to 115 degrees Fahrenheit. Lower temperatures are best for tender plants. Since most home ovens cannot achieve the recommended temperatures for herb drying, food dehydrators have become popular. Many dehydrators come with wire racks so air can flow through the leaves. Arrange the leaves/stems across the rack so they are not touching. Overcrowding during the drying process can result in longer dry times. You can use a mesh-style rack for small leaves to provide air circulation. A tip for selecting a decent food dehydrator is to make sure that it can adjust the drying temperature and time. Select a unit that can dry at as low a temperature as possible to provide the most control over the drying process and quality. Increased heat levels might be needed to compensate for humidity levels. Using heated air to dry herbs can result in a higher loss of essential oils than using air-dried herbs. The amount of time needed to achieve a crisp, dry product that can be easily crushed is variable. Humidity, plant water content, and temperature are all factors to consider. For this reason, I recommend checking on the plants often during the drying process.

For either drying method mentioned above, it is important to note that any moisture left in the plants after drying can lead to spoilage. If your drying space seems to be “too moist” meaning you cannot achieve a crisp dry texture, increase the temperature, and air circulation. A process of trial and error may be needed as the time of year and the water content of plants can vary.

To prepare the dried herbs for storage, the leaves are removed from stems and crushed to the desired size. A tip for this step is to place the dried herbs into a bag and push the leaves off the stems. Set aside stems as you push the leaves into the bag. When the biggest stems are removed, crush the leaves inside of the bag to the desired size. Sift through the dried product to remove smaller stems to achieve the best consistency for cooking. Rougher dried herbs can be used for teas. It really is up to personal preference as to how “clean” the final product will be. Some choose sifters or screens to further improve the visual appeal of the end product.

Freezing –
A quick and straightforward way to preserve herbs for later use in cooking is by freezing. Individual leaves can be placed in single layers on cookie sheets and then flash frozen. Cut chives work well this way. Once frozen, place the herbs into storage containers to reduce exposure to air. Another freezing method is to chop the herbs and load them into ice cube trays, then fill with water. Once frozen, put the cubes into storage containers and add them to recipes when needed. Alliums (onions and garlic) can be easily processed this way, also. The biggest downside to freezing is the required storage space in your freezer and a shorter shelf life.

Other methods include layering whole leaves in salt or oil. Herb essential oils can be transferred to other liquids for use in cooking. For example, herbs can be steeped to create herb-infused vinegars or oils. These methods take more time and care than can be covered here, so more research and preparation should be taken before trying these options. Microwaving takes a bit of trial and error to get the right cooking time for the type of herb used and varies with different types of machines.

Most herbs can be processed successfully in a variety of ways for different uses. A good tip is to experiment and see which techniques work best. Gardeners who experiment, find the methods that work best for their intended use.

Storing Herbs –
Dried or dehydrated herbs do not like exposure to light and air, especially moist air. A simple and effortless way to store extra dried herbs is to put them into marked zip lock bags or a vacuumed sealed mason jar. Once each herb is in its container, they will need to be placed in a dark area like inside of a canister or storage container. Keep your herbs in a cool dry area because exposure to heat during storage can affect essential oil content. Storage time will vary on the herb, but if stored properly, they can last for months or longer.

The two most important tips of all are to grow what you will use and grow from seed for the best plant selection.

What to do with your late-season bargain plant purchases?

Now that you’ve found those irresistible gems at marked-down prices how do you set them up for success in their new home?

By: Diana Wisen, Skagit County WSU Extension Master Gardener

It’s late summer, and you’ve found some plants on sale that are calling to you. Gardeners, like everyone else, love a good bargain. But when is a marked-down plant a good buy, or is something better left on the rack? Gardeners tend to be “nurturers” who hope that with plenty of TLC, they can nurture a plant back to full health. That may or may not be possible. You rarely can heal sick plants. Despite your efforts, diseased or heavily damaged plants are not a bargain at any price. Be forewarned! You could be bringing additional problems into your yard.

Nevertheless, you have given into temptation and brought home several marked-down plants. Now, what to do with them? First, take them out of your vehicle as soon as you get home, put them in a shady, cool place, and water them well. Allow the plants to drain. Once they are fully hydrated, do not leave them in standing water. Roots need air and will suffocate if left in standing water for several days. Check for baby slugs by sliding the plant out of its container. Also, check for healthy roots before putting it back in its container. Cut off dead stems, leaves, and flowers, but leave all healthy leaves so the plant can photosynthesize and grow.

Do you have a place in mind for each plant? Buying plants without a place to plant them can lead to a “Driveway Garden” with many potted plants sitting too long on the path to your house while waiting to be planted in your garden. This is not an unheard-of dilemma among gardening friends. However, let’s assume you have a place for your plant. Check for pests, disease, and damaged parts, including the roots, before planting. This should be done before you purchase the plant, but it’s better now than after it’s in the ground. Look for aphids, root maggots, beetle larvae, brown mushy (dead) roots, wounds on the stems, and diseased leaves. Sometimes, you can get away with cutting off diseased portions, but often the disease is in the vascular system and plants don’t “heal” like humans do. If you suspect disease, it is best to put the entire plant in the garbage can, not in your compost pile.

Check for healthy roots. Cut off dead stems, leaves, and flowers, but leave all healthy leaves so the plant can photosynthesize and grow.

Where to put your new plant
Read the plant tag to learn the conditions the plant needs to thrive. Can you provide the right kind of soil and drainage? What about the amount of sun or shade? Heat requirements? Wind protection? Are deer a problem? It is your job to give your plant what it needs. It cannot get up and move to a better site by itself.
How to plant
Planting is best done on a cool day or in the evening of a hot day. Water the plant and the planting spot ahead of time. Dig a hole the same depth as the plant’s root mass and three times as wide. Loosen the soil around the sides of the planting hole so the roots can grow outward. Place the plant in the hole and fill with the soil you took out. Water it in to settle the soil. Light mulching can help retain soil moisture and reduce weeding.

For shrubs and trees, the root flare supporting the trunk should be clearly visible and not covered with soil or mulch. Take the plant out of the container and examine the root zone. Sometimes marked-down plants are root bound and some serious root pruning will be needed before planting. Cut off circling, broken, kinked, or damaged roots. Very long roots may need to be shortened. Do not cut off any of the canopy. Dig a wide, shallow hole, spread the roots straight out in all directions, replace the native soil, and water it in well. Do not stomp on the root zone. Make sure the base of the trunk is at the same level or a bit higher than the soil level. Mulch with arborist chips, keeping them an inch or two from the trunk.

Fertilizing and Care
Sometimes, you can tell by looking at the leaves if a plant is deficient in a nutrient. You need to know what is typical for this plant at this time of year. There are plenty of plants for which yellow or light green leaves are normal. Usually, fertilizing with a diluted nitrogen fertilizer at planting time is helpful. Just go easy on the fertilizer and avoid burning the roots. Too much fertilizer for shrubs, trees, and some perennials can cause excessive weak growth late in the season, which will be subject to winter damage. Soils here in the Pacific Northwest already have plenty of phosphorus. Adding phosphorous can kill the beneficial mycorrhizae. Do not add products such as vitamin B to the soil or spray leaves with a desiccant to prevent wilting. Despite manufacturers’ claims, they are not helpful.

A plant is considered established when its root system can take up sufficient water and nutrients for the plant to grow normally. Some shrubs and trees can take over a year, so remember to water them regularly, even if they are drought-tolerant. An arborist chip or homemade compost mulch will help keep the soil evenly moist and add slowly released nutrients. Most purchased composts are fine for a top dressing to retard water evaporation, but they have little or no nutrients left in them because they have been heated to very high temperatures to kill any possible pathogens. Many gardeners now use the “chop & drop” method of leaving plant debris on the soil to decompose naturally and add nutrients to the soil, becoming nature’s slow-release fertilizer.

Container plantings require a different regimen.
Use a light soil mix, not garden soil for container planting. Add some of the compost mixed in well. A sufficiently sized drainage hole needs to be in the bottom of the pot. If slugs crawling in are a concern, put a coffee filter over the hole before filling. Do not put pieces of crockery or a layer of gravel over the hole in the container. New research shows this practice, which is frequently recommended in garden books, actually impedes drainage. Put the potting mix soil to the bottom of the pot so the roots will have plenty of room to grow. While urn-shaped containers are beautiful, they are more challenging to change out later on because the rim curves in and large established roots get caught under it and can be very difficult to dig out. Container plantings dry out much faster than in-ground plantings, especially as the roots grow and fill the pot. Frequent watering causes nutrients to be flushed out sooner so container plantings of annuals will need additional fertilizer during the growing season. A slow-release fertilizer can also be used. Always read the directions thoroughly before using any garden product.

Deadhead annuals to keep them blooming until frost. If they start making seeds that process signals the plants to stop producing additional flowers because they are nearing the end of their life cycle. Some containers can be brought indoors in the winter and continue to thrive if there is sufficient light. 

Now it is time to enjoy your new plants. Observe them daily and check to see if they need watering. Watch for plants starting to wilt and water them immediately. It’s OK to water plants in the middle of a hot day. Watering them will not cause leaf scorch but will keep your plants alive.

Some perennials may start to die back because they are at the end of their growing season and beginning to go dormant. Plant them properly, and they will come up next spring. Other perennials can be cut back, and they will produce a flush of new growth and perhaps lightly bloom again. Don’t forget to bait for slugs and snails, which can be treated the same. This time of year slugs are starting to lay their eggs, which look like masses of tiny white pearls in the moist soil. Slugs and snails live deep in the soil during winter. Read more about managing slugs and snails: https://www.skagitmg.org/managing_slugs_snails/

With the long growing season in the Skagit Valley, your new bargain plants can give you many months of pleasure. Enjoy the colors, textures, leaf shapes, plant forms, flowers and seeds, fragrances, and the overall beauty they add to your life and your neighborhood. It’s your garden. Plant what you love.

Keep the Fresh Produce Coming!

With a little effort now, it is possible to bring fresh vegetables to the table until October, November, and beyond.

By: Valerie Rose and Ginny Bode, Skagit County WSU Extension Master Gardeners

It can feel heartbreaking to bring in the last head of lettuce, knowing that soon you’ll need to make the transition to store-bought vegetables. But wait, more and more savvy gardeners extend the growing season by planting cool-season vegetables in the warm summer months of July and August. It may seem counter-intuitive until you try it and experience the bounty of harvesting late into the fall.

Selecting the Right Varieties is Key
Planting a fall/winter garden requires seeds and plants proven to grow well in summer heat, then ripen as the daylight shortens and the temperature drops. By planting from July to August, your fall harvest can include leafy greens, cabbage, broccoli, and Brussels sprouts, along with carrots, beets, and other root vegetables. A light frost even brings out the best flavor in collard greens and parsnips! Now is the time to plant, selecting a location with the maximum amount of sunlight as fall moves toward winter.

Plan to plant from July to early August. The chart below can be used as a guide along with the information on the back of the seed packet.

Retrieved from: https://extension.wsu.edu/snohomish/fall-and-winter-vegetable-gardens-for-western-washington/

Look for seed catalogs that focus specifically on fall/winter gardening in west coast or northern climates. They feature helpful charts with planting dates. They also include a reminder that gardeners must plant earlier if they’re growing in a colder zone than the seed company’s locations. It is also an option to leave this step to a commercial grower and buy plant starts from a nursery or garden store. Read the label carefully to ensure you’re getting a late-season variety.

If you have a greenhouse, you can learn from writer and educator Eliot Coleman. He farms year-round in coastal Maine, harvesting fresh produce from snow-covered, unheated greenhouses. In his classic guide, ‘The Winter Harvest Handbook,’ Coleman coaches novice and experienced gardeners in extending the growing season. Another resource, Winter Gardening in Maritime Northwest: Cool Season Crops for the Year-Round Gardener, by Binda Colebrook, is especially suited for our region.

Preparing a Space: Look for the Sunny Side
Make a sun and shade map of your yard or patio. Yes, your container garden can also grow cool-season vegetables if it gets enough sun. Your fall/winter garden needs to be in a spot where the low-lying sun will still find its way into your yard, as it arcs low across the southern sky. Remember, your garden will gain more sun as the deciduous trees conveniently drop their leaves, blocking much less light. Note which buildings and fences on the southern edge of your yard will cast longer shadows as the days get shorter, causing deep shade for months.

Raised beds will keep your garden from drowning in rains that accompany the season change. A bed made of boards or cement blocks also provides an easy place to secure hoops for supporting row covers. Read more about the multiple options to extend the growing season in this Ask a Master Gardener blog article on season extenders: https://www.skagitmg.org/season-extenders/

Getting Started: When to Start Indoors, When to Seed Outdoors
You can either sow seeds directly into the garden or start the seeds indoors to grow sturdy young plants that can later be transplanted. The back of the seed packet may tell you this, or  check out the WSU Extension home vegetable planting guide. The seeds for root crops, such as carrots and beets, are best sown directly in the soil to avoid damaging the roots when transplanting.

Some gardeners prefer to start seeds indoors where they can monitor the soil and protect the seedlings from pests. If you do start seeds indoors, aim to do so 3-8 weeks before planting them in the garden. The exact timing will vary for each vegetable, depending on how long it takes to grow from seed to a transplant-sized seedling. For example, broccoli and cabbage typically take about 5-6 weeks from seed to transplanting. So, it would be best to start broccoli seeds around the beginning of August to have seedlings ready for transplanting by mid-September.

To provide warmth and light for indoor seeds, you can use a sunny window, an electric light with a germination heating mat, or a plastic or glass-covered hot box. It’s essential to plant into a seedling mix, not simply potting soil. After germination, increase lighting to prevent tall, spindly plants. See the Skagit Master Gardener blog article about starting seeds indoors here: https://www.skagitmg.org/indoor-grow-stand/

When moving young plants from indoors to the garden, it’s crucial to gradually harden them off by exposing them to the outdoor environment. Not doing so could cause sunburn and stress for the plants. To harden off the plants, place them in a location outdoors that receives 2-3 hours of sunlight for the first couple of days and bring them inside at night. Gradually increase the time in the sunlight and wind conditions for a week before transplanting into the garden. 

Whether direct planting or transplanting seedlings, prepare the garden soil by adding compost and organic matter to improve its texture and fertility. Be prepared to water daily, during the driest time of the year. You can water by hand, or set up a drip irrigation system to consistently water through the hot days of summer. See the Skagit Master Gardener blog article on drip system: https://www.skagitmg.org/diy-drip-irrigation/

Be sure to mulch between seedlings and rows. Straw or other mulch will retain soil moisture at the plant roots, which is crucial during the warm days at the end of August and in early September. Mulch will also suppress weed growth. Keep in mind that plants grow slowly in the diminished sunlight starting late October. Therefore, some gardeners can grow their plants to harvest stage beginning in late November. Then the cool air and soil can “store” the mature cool weather crops until you harvest. 

The successful gardener will be rewarded by protecting young plants from pests and providing them with some shade if the weather gets too hot. It is important to regularly monitor the growth of the plants, provide adequate support if needed, and address any signs of disease or nutrient deficiencies. 

Take time at the height of summer to plant a fall/winter garden. The fresh, delicious harvest will brighten your autumn and winter meals.

The Discovery Garden
Skagit County WSU Extension Master Gardener Discovery Garden features 30 themed garden rooms on 1.5 acres with ADA-accessible paths and educational displays. Designed to support Skagit home gardeners by promoting research-based gardening practices, master gardeners have created 30 garden rooms within the garden, featuring hundreds of plants chosen to flourish in Skagit Valley. Master gardeners will be on hand to show you their favorite plants.

The Discovery Garden began in 1994 when the Skagit County WSU Extension Master Gardeners had a vision for a garden that would demonstrate best practices for gardening in the Skagit area. After two years of planning, the garden’s first plantings of trees and installation of fences was completed in the fall of 1996, transforming a rural agricultural field into a public display garden. Check out the garden’s webpage and browse the 30 garden rooms to find inspiration for your garden.

Salal Native Plant Garden
The Salal Native Plant Garden is a half-acre oasis of native plants tucked behind the Discovery Garden. You can enter by walking through the Discovery Garden and following the paths to the south. Cool off in the shade and explore how you can incorporate low-maintenance natives into your home landscape. See how red osier dogwood, salal, cascara, vine maples, and others could look in your yard. Docents will be available for tours and to answer questions.

The Salal Native Plant Garden was created twenty-five years ago as a collaborative effort between volunteers of the Salal Chapter of the Washington Native Plant Society and the Washington State University Agriculture Extension Agency at Mount Vernon (WSU). 

NW Fruit Garden
The NW Fruit Garden (formerly WWFRF) is six-acres planted with fruit trees, berry bushes, and other fruit-bearing plants suited for our climate, along with espaliers and informative signage. Tour the Antique Apple Collection in the orchard’s inner oval or tour the entire orchard. Ask about pruning and thinning of fruit. Find out what fruit varieties are best for your needs. The garden includes many unusual plants, such as medlar, sea buckthorn, kiwi, Aronia, and haskaps.

The NW Fruit Garden is located on the west side of the Discovery Garden. The garden was initiated in 1991 to provide a resource for the public to view successful fruit varieties and cultural methods for our Pacific maritime climate. Whether you are choosing two or three fruit tree varieties for a small urban backyard or have a more extensive orchard for family or even farmers-market production, NW Fruit has information on variety selection and fruit culture for the Pacific Northwest.

Tap into Great Gardening Advice at a Master Gardener Plant Clinic

An amazing depth of knowledge and resources are available for home gardeners through Master Gardener Plant Clinics and Info Booths throughout Skagit County.

By: Ginny Bode and Anne Hays, Skagit County WSU Extension Master Gardeners

Problem with your roses? Does your fruit tree have a virus or a fungus? Is something attacking your pepper starts? Need help identifying plants in your new-to-you garden? Perhaps you have been out and about admiring your garden and noticed that all is not well.

Rather than depending on your neighbor or an online group’s collective input (which may or may not be accurate), visit a plant clinic and get answers to your questions from WSU Extension-trained experts. Master gardeners are an arm of the Skagit County WSU Extension office. They are rigorously trained in scientific gardening methods based on research conducted by leading agricultural institutions.

You’ll find answers to your questions and thousands of other issues faced by home gardeners in Skagit County at a Master Gardener Plant Clinic. Drop in at one of the locations throughout the county, all free of charge, spring through fall.

What does science-based gardening information mean?
Master gardeners stand on the shoulders of agricultural research powerhouses such as Washington State University and Oregon State University. These land grant universities support the agricultural industry through research, which includes testing soils, finding solutions for diseases, and identifying the best cultivars for specific climates.

All master gardeners sign a commitment to only offer solutions proven in a university research setting. That means we won’t recommend a solution that isn’t proven reliable and safe. The extensive training includes integrated pest management or IPM. These solutions aim to “reduce human health risks, minimize adverse environmental impacts, and maximize economic returns and sustainability.” Clinic volunteers will help you find a solution that best meets your gardening goals. We’ll give you options if you don’t want to use pesticides. If you do want to use strong chemicals, master gardeners will outline the options and safety measures. Sometimes, the plant is in the wrong place, or a disease is in the soil, and the plant will never be successful. Then, clinic volunteers will recommend removing the plant and starting a new one with a disease-resistant cultivar rather than fighting an ongoing issue for years.

Who are the plant clinic experts?
You will be astounded at the scientific backgrounds found among the master gardeners who work at the plant clinics. Trained through the Skagit County WSU Extension Master Gardener Program, many core volunteers are retired from bioscience, forestry, and geology careers. Through years of diagnostic study and training, others have become experts in fruit tree diseases or insects. At a plant clinic, master gardeners work as a team to identify the problems and regularly cross-check diagnoses. Any master gardener will tell you that clinic experts are rarely stumped. If they are, they won’t stop until they find the answer.

Master Gardener Allison Hitchcock remembers one of the more unique plant identification challenges: “A client came in and wanted us to identify one of many large pits found piled on her property (likely dumped). I was having lunch at the time and just finishing my mango and easily identified the discarded pits with the one in my hand.”

Proper identification is critical to recommending a solution with the least risk or harm to the environment and surrounding living beings. © Skagit County WSU Extension Master Gardeners

Master Gardener Gail Messett remembers an Anacortes clinic visitor who was a fellow master gardener from North Carolina: “She was so glad to see us. She was visiting her son stationed at Whidbey, who had recently purchased a house in Anacortes. She wanted to help him reclaim his mature garden and needed help identifying existing plants and what plants work in the Pacific Northwest. She went back to his house and returned with pictures of plants for us to identify. And, of course, we could suggest native and other plants that would work well in our climate.”

Common Plant Clinic Questions:

• Plant disease diagnosis and treatment suggestions
• Insect identification (and control options, if necessary)
• Plant selection ideas
• General gardening advice, such as pruning techniques, weed control, and pesticide/herbicide application tips
• Gardening resources guidance: We can put you in touch with soil-test sources, native plant societies, mushroom identification sources, and much more

Two Locations in Skagit County
The clinics in Burlington and Anacortes have a library, print materials, access to online resources, and microscopes for plant identification and disease diagnosis. The Anacortes plant clinic is open during the Farmers Market and often attracts visiting tourists or those new to the area and interested in local plants.
Bring Your Suspicious-Looking Plant Materials
Plant clinic volunteers are eager to hear your questions and diagnose plant issues. The questions brought to the clinic also help identify trends throughout the county. Live samples are preferred, either in a baggie or jar, but the team can also work with suitable photos and, often, verbal descriptions. For plant ID, you should include a small branch and any flowers or fruits. Insect and disease samples should include both healthy and affected tissue/branches. Photos should consist of both close-up and landscape shots.

With the information you bring, the plant clinic team will ask questions, use microscopes, and research a comprehensive library of reference materials. Drawing on science-based training and years of experience diagnosing local garden issues, plant clinic master gardeners will track down the source of the problem and offer advice on the least invasive methods to set you on the right course for recovery.

Remember, there are many reasons your plant may not be thriving. Perhaps it is a tender specimen homesick for warmer climates, or it might prefer a sunnier or shadier location in your yard. It might perk right up with some soil amendment and a different watering regimen. Stressed plants are more susceptible to insect attack and disease. A virus or a fungus might have settled in, or tiny insects might be emerging to feast. The solution could be as simple as picking off the damaged leaves, instituting good winter cleanup practices, or using a handheld sprinkler to wash insects off leaves. A visit to a Master Gardener Plant Clinic will help you solve your gardening challenges and decide what to plant next.

Skagit Master Gardener Plant Fair-A Growing Tradition

Enjoy fun for the entire family on Saturday, May 11, 2024  8 a.m. – 2 p.m.

By Claire Cotnoir and Hank Davies
Skagit County WSU Extension Master Gardeners and Co-Chairs of the 2024 Plant Fair
Thirty Years and Growing
On Saturday, May 11, 2024 (the Saturday before Mother’s Day, per tradition), the Skagit County Master Gardener Foundation will hold its annual Plant Fair, taking over the entire Skagit County Fairgrounds in Mount Vernon from 8 a.m. to 2 p.m. offering something for every gardener.

The annual Plant Fair kicks off summer for Skagit area gardeners with thousands of quality garden plants for sale, all locally grown or selected by Skagit County Master Gardeners and chosen for success in our local environment. The event is free, parking is free, and master gardener plant recommendations and advice are free. Thousands of plants and other items are available at very reasonable prices.

The Skagit County Fairgrounds, at 501 Taylor Street, is just south of downtown Mount Vernon. Follow the signs to the south entrance on Taylor Street. Note: although the parking area is ample, it is not unusual for a line to form in the earlier hours of the event. Pack your patience, or consider coming a bit later.

The scene at the opening gate is always exciting and has grown over the years.

Sometimes, It’s Fun to Look Back
Gardeners are often surprised by old photos of their gardens and are always delighted by the growth and development they’ve seen since. Plants grow, gardens grow– and boy, do gardening events grow! As Skagit County WSU Extension Master Gardeners are growing and grooming plants to prepare for their 30th annual Plant Fair, they share fond memories of their earlier, smaller events.

The Plant Fair originally started in a field beside what is now the Discovery Garden on Memorial Highway. It moved to the Skagit County Fairgrounds in Mount Vernon in 2015, first occupying one building, and now spreading across the entire fairground with many, many plants, vendors, music, learning sessions and more.

The space allotted for master gardener plant sales, demonstrations, the plant clinic, and The Emporium has also grown all in spacious, comfortable indoor spaces. You’ll find the space for vendor booths, which has also grown, with indoor and outdoor spaces.

Some things couldn’t really grow much bigger. The cashier banners, for instance– this event is a fundraiser, after all! And as always, the master gardeners will be showing off their (often) large, unique hats.

Master Gardener Plants Are the Best!
If you’re looking for tomato plants, head straight for Building D (affectionately dubbed The Tomato Barn), where more than 3,000 plants will be available. You’ll find 40+ varieties that have proven to be favorites of Skagit Valley tomato lovers, plus limited numbers of some “rare and unusual” types. New this year is the Skagit Dwarf Tomato Project. In response to many requests for tomato plants that could be grown in a pot on a deck or condo/apartment balcony, master gardeners have sourced a limited quantity of plants that perfectly fit this need. Look for a table of dwarf varieties at the back of the barn. Or ask one of the many master gardeners for assistance. Check out the tomato list here.>

Like last year, the vast Pavilion building will host a variety of annual and perennial plants, both ornamental and edible. This year’s fair will feature spectacular flowering plant varieties, including Lisianthus, an uncommon and beautiful rose-like plant that is notoriously difficult to start. Master gardeners have done the hard part for you. Lisianthus will be available in apricot, green, and white this year. Hanging baskets of Fuchsia and Coleus pots will be ready for Mother’s Day gifting. Many more varieties for sale include Cosmos, Dianthus, Eucalyptus, white lace flower (Orlaya grandiflora), Scabiosa, snapdragon (Antirrhinum majus), stock (Matthiola incana), strawflower (Xerochrysum bracteatum), Zinnia, bellflower (Campanula spp.), bells of Ireland (Moluccella laevis), love-in-a-mist (Nigella damascene), and Silene ‘Blushing Lanterns.’

Chose from an abundance of annuals and perennials in the Pavilion.

You’ll find 40+ proven favorites of Skagit Valley tomato lovers, plus limited numbers of “rare and unusual” types.

In the vegetable section, master gardeners have grown popular varieties well-suited to the local climate. A few examples of the vegetable and herb starts you will find include beet, broccoli, cabbage, cucumber, Florence fennel, kale, leek, melon, onion, pepper, pumpkin, Swiss chard, shallot, spinach, summer squash, winter squash, tomatillo, basil, chive, cilantro, and dill.

As always, a wide variety of perennials will be available, including many native plant varieties and edibles like berries, rhubarb, grapes, figs, and perennial herbs. Of course, you’ll find perennially popular peonies! And for the first time, beautiful ‘Spider’s Web’ Fatsia. Also, ferns, trees, shrubs, iris, hardy geranium, Hosta, Epimedium, Trillium, Delphinium, wild ginger (Asarum canadense)-the list goes on. New this year, a pollinator exhibit will help you understand which plants attract which pollinators, their bloom times, and the importance of pollinators for our gardens and the planet.

Bring your plant questions to discuss with a master gardener at the plant clinic held in the Pavilion.

Get ready to go! Bring your boxes, carts, wagons, and, most importantly, your wish list.

Plants and So Much More
Just inside the Pavilion’s main entrance, master gardener plant clinic experts will help you with plant questions and problems. Across the aisle, shop at The Emporium for lightly used garden tools, books, art, and vases. Here, you’ll also find information on the Skagit County WSU Extension Master Gardener Program, upcoming events, and how to become a master gardener.

Get your pruners ready-the popular tool sharpening station is in the Pavilion this year and with increased staff. Bring your tools and let our tool experts prepare you for all your summer gardening exploits.

As you exit the Pavilion, head next door to the ‘Free Parking for Paid Plants’ area, where you can “park” your purchases while you continue shopping and enjoying a bite to eat and music in the picnic area. Our popular plant-parking service is returning this year with help from local 4-H members. In Building G, 4-H will also host their annual Small Animal Fair.

All along the grass fairway and in Building C, Plant Fair visitors will find a variety of vendors selling handcrafted wares such as jewelry, glass/metal art, wood sculptures, and gardening equipment. Plus, more plants! Visit educational booths to learn about noxious weeds, energy conservation, bats, and bees. Locally sourced food and drink vendors will be on hand to keep your energy up. Check out the vender list here.>

On the grass fairway vendors will be selling more plants, garden art, food and more.

A wide variety of perennials will be available, including many native plant varieties and edibles.
Demonstrations for Learning
Try attending one of the short gardening demos from 9 a.m. to 1 p.m. presented in Building B. Demo topics include pruning, planting tomatoes, gardening with native plants, and more. You may already know Building B as the quilt building if you regularly attend the annual Skagit County Fair. This year, the demonstration area will surrounded by a colorful display of garden-themed quilts on loan from master gardeners and friends.
Get Ready to Go
Bring your boxes, carts, wagons, and, most importantly, your wish list! To help you plan, tomato variety descriptions, plant lists, a vendor list, and demonstration schedules will be available by the end of April on the Skagit County Master Gardener Foundation website at https://www.skagitmg.org/plant-fair.

Happy customers at the plant fair!

Pick up your tomato favorites from the 3000+ plants selected for our climate and grown by local master gardeners.
Supporting Skagit County Gardeners
Proceeds generated from the Plant Fair enable the Skagit County Master Gardener Foundation, a non-profit organization working in partnership with Washington State University Extension, to support home gardeners by promoting science-based gardening practices and education throughout the year.

The Tents are Coming-No Cause for Alarm

Caterpillars signify new, rejuvenating life

By: Virgene Link-New, Skagit County WSU Extension Master Gardener

Perhaps it is our fatigue, our weariness with the darkness of winter. Or maybe it’s our eagerness to see the lush new green of spring bursting forth that fuels our distress and disappointment over the early spring appearance of caterpillar tents in our trees.

Do not despair. Those tents are a sign of another type of life bursting forth: one that will replenish soil over-watered by winter rains and feed many species who have suffered from hunger during the winter. Those tents indicate the under-appreciated western tent caterpillar, Malacosoma californicum. There is also a forest tent caterpillar that is less common, Malacosoma disstria. The first is our most common tent maker in this region. Others are called webworms or tussock moths.

Their egg cases were deposited on deciduous trees and shrubs last year in the late summer and early fall. An egg case is many eggs “glued” together to form a “mass.” In the case of the tent caterpillar, it looks like a silvery Styrofoam mass when fresh. As the temperature warms, the eggs begin to hatch. The newly emerged hatching caterpillars spin a silken web to provide themselves with some protection from predators and weather. At first, they feed inside the tent, then they enlarge their tent as they grow. Since these caterpillars feed in early spring, the young leaves they consume are essentially recycled into compost that rains down to replenish the soil. The host tree has enough time to grow new leaves after the caterpillars have departed. Often, you see caterpillar tents in trees that later fail to develop. This is probably due to weather or other factors like disease or fungus.

As they grow, the caterpillars eventually leave the tent and wander about, searching for more leaves to eat and a place to spin a cocoon. They undergo complete metamorphosis, the process of changing from an immature form to an adult form. At this time, they are more easily preyed upon by other insects, spiders, birds, small mammals, reptiles, and amphibians. Even their cocoons can be food for other species. Once they have emerged as moths to mate, they are more easily consumed by birds and bats. They are also vulnerable to viruses, diseases, and fungi.

Now, if you are in business and your livelihood depends upon fruit production or tree production, then action is necessary as energy is spent on producing more leaves. Also, the tents can interfere with setting of fruit. Orchardists act in the winter to remove the egg cases by peeling them off or pruning them out of the branches. The removed egg cases can be harmlessly dropped directly on the ground, which makes them available to predators like ground beetles and centipedes and allows any natural enemies whose parasitized eggs have been deposited in the egg case to exit!

If you have a small, just-planted tree, you should do the same action as the orchardist since unestablished trees are more vulnerable to stress. Or an ornamental tree by your front door would be aesthetically displeasing with tents, and you might want to take some action in that case. If you’ve missed the window for removing the egg cases, the web with caterpillars inside can be pulled off or pinched when cool or in the evening if pruning would distort your desired shape. These mechanical removal methods are more environmentally friendly than the use of pesticides and do not result in chemical run off during rainfall that eventually reaches Puget Sound. As a reminder, please do not use a torch to burn the tents, as fire is more damaging to the plant than defoliation.

Larger trees will put out new leaves and should be less vulnerable to attack the following year as they seem to develop some resistance. Weakened trees are partially killed only when severe infestations (total defoliation) are combined with drought or other stressors (like disease). In forests where trees are too overcrowded for nutrients and moisture, this is a form of natural thinning.

Proper mulching helps trees withstand drought because water can reach the entire root system. © Virgene Link-New

These past several years, the Pacific NW has been impacted by drought. Although tent caterpillars do not impact conifers (evergreens), their obvious dead tops in our landscape indicate that our trees suffer from a lack of water.

To protect the trees in your landscape, ensure they receive at least one inch of water per week out to the drip line. This is one reason the WSU Extension Master Gardener program recommends not having grass or plantings directly under your tree. You can use a moisture meter to read the depth to which water (rainfall or supplied) is reaching.

Our native trees have evolved with our native insects and thus have a symbiotic relationship that benefits the entire food web. Particularly, the tent caterpillar seeks out red alder in the native forest. Other host plants are those in the rose, birch, and willow families, to name a few.

Later in the year, we hardly notice the trees that hosted tent caterpillars, as we’ve forgotten which trees were defoliated in the abundance of new leaves. Please be tolerant of some damage because this species plays an important role in the ecosystem.

Get Your Body Ready to Tackle the Gardening Chores Ahead

“The secret to a healthy garden is a healthy gardener.”
– Canadian Physiotherapy Association

By: Kathy Wolfe, Skagit County WSU Extension Master Gardener

Let the gardening begin! As March arrives, our gardening instincts kick into gear and we feel the urge to get started. We look forward to preparing our gardening beds, applying compost to the soil, plunging our first pea seeds into the ground, getting a head start on slug control, planting asparagus crowns (thankful that you dug those trenches last fall), and starting seeds in a greenhouse or under grow lights. Another activity to add to your to-do list is to get your body ready to tackle the gardening chores for the year ahead.

If you routinely work out at the gym, are a yoga devotee, or were lucky enough to spend your winter in a warm climate where you remained active for months, good for you! Many of us, however, have been hibernating along with our plants and should consider how we will prepare our bodies for the shoveling, lifting, hoeing, and raking activities soon upon us. It takes time to build strength, stamina, and aerobic power to prevent injury.

When moving something, keep your back straight and avoid arching it. Use your leg and buttock muscles instead of your arms. © Photographer: Yan Krukau | Pexels.com

Why bother, you ask? If your core strength is low, your balance will be affected, and falls could result. Big and small muscles must be strong and pliable to avoid tears, cramps, and sprains. No one wants that.

Before our gardening marathon, let’s begin by practicing easy, at-home exercises. By starting today, your body will be more prepared for the heavier gardening chores still to come. Be sure to check with your medical professional before starting any new physical regimen. The tips presented here are in no way intended as a substitute for medical consultation.

Get Out and Walk
Boost your heart health and stamina with a brisk walk to get the blood circulating into your large muscle groups. Twenty to thirty minutes, done three times per week, is advised for cardiovascular health.
Chair Squats
Stand in front of a chair, feet shoulder-width apart, arms in front of you. Bend your knees, slowly squat, and gently sit down, then stand up using only your legs. Repeat several times. This exercise will benefit your quadriceps, glutes, and hamstrings, helping your functional strength.

Proper lifting techniques protect the back.

Exercises using a chair for balance are a great way to tune-up the body core muscles for functional strength.

Wall pushups help strengthen your chest, shoulders, triceps, abs, and wrists.
Wall Pushups 
Stand facing a wall with your hands shoulder-width apart. With your arms straight, place your palms on the wall. Keep your back straight, bend your elbows into a pushup position, and then push yourself away from the wall while keeping your palms in contact with the surface. This exercise strengthens your chest, shoulders, triceps, abs, and wrists.
Balance
Try standing on one leg and using fingertip touch on a countertop or chair. Repeat with the opposite leg. You can do this while performing everyday tasks like washing dishes or brushing your teeth. Try walking heel-to-toe. Practice leaning down and standing up, holding onto a chair if necessary. You will be doing a lot of this in the garden.

Now that your body is becoming more toned, balanced, and flexible, it is important to carry it gently into each gardening day. Start with some basic stretches. Remember, for any stretches, it is important to warm up with a few minutes of physical activity like walking, stretch at least two or three times alternating side to side, keep good form and posture (standing tall with your shoulders back and relaxed, hips even and core engaged to support your back), and keep breathing throughout each stretch. You might feel a pulling sensation or slight discomfort, but you should not feel pain with any stretch. And never bounce while stretching, but hold the movement steady. Print out these basic stretches and post them as a reminder and an easy reference.

Begin with some basic roll-downs for back flexibility and balance practice.

Further, prepare your back and spine with several thoracic rotations on each side, bending and twisting the spine to increase flexibility.

Warm up your pectorals (chest muscles) using a doorframe or corner to create resistance.

Don’t forget your wrists. Do a few wrist flexor and extensor exercises to get you started.

Do gentle quadriceps, gluteal, hip flexors, and calf stretches to prepare your legs for action.

Now that you are warmed up start with a gentle activity such as raking to help get the blood flowing through your large muscle groups.

Different tasks require specific attention and care. For example, the proper weeding technique is to dig around all sides of the weed to loosen it up before attempting to yank it out. Use your tools to do the work for you whenever you can. And alternate your weeding stance between standing and squatting. If you kneel, use a kneeling pad or individually pad your knees to protect them from excessive pressure.

Good tips for lifting and moving heavy items include planning where you will move the object and removing obstacles before lifting anything. Place the item close to your torso and bend your knees. Take a deep breath to prepare yourself and initiate the lift on the exhale. Use your leg and buttock muscles instead of your arms. Keep your back straight and avoid arching it. Limit the rotation of your spine because this will put undue stress on your lower vertebrae. Use your feet if turning is necessary. Refrain from jerking a heavy load, or you might be visiting a physical therapist the next morning.

Alternate gardening tasks and positions throughout the day and keep well hydrated.

After a day of gardening, take a few minutes to cool down by doing some of the warmup stretches shown. Take a short walk to keep your large muscle groups moving freely. A walking inspection of the rest of your yard may be in order. This practice will help prevent those nasty back and leg aches later in the day.

Doing some strengthening work before the gardening season, starting each garden day with some stretches and light work, and ending your session with a nice cool down will become habits if you repeat them regularly. Your body will thank you for it!

Gardening for All Ages and Abilities

Practical tips and ideas for adapting the garden through life’s transitions

By: Ginny Bode with Madelyn Case and Anita Reetz, Skagit County WSU Extension Master Gardeners

Gardeners know spending time in the garden feeds the soul. But sometimes, as life changes, we face the need to adapt how we garden so it is possible for ourselves or those we love to continue cultivating wellbeing through gardening.

For some, physical limitations present lifelong challenges; for others, aging begins to interfere with the bending, kneeling, and digging associated with gardening. There are many reasons to take heart and continue to enjoy gardening by implementing some of these adaptive methods.

In her book Gardening for a Lifetime, Sidney Eddison sums up the reason for adapting when she says, “We are all doing exactly the same thing-trying to hang on to something we love.” Her book is loaded with practical ideas for reducing and removing barriers that hinder and continue the joy of growing plants through life’s transitions.

Reducing the size and work of a garden is the first step, followed by making it easier, more accessible, and user-friendly. A vegetable garden the size you’ve always had, and probably shared with others, can be resized to reduce both the work of maintaining and the work of harvesting. Choose to grow your top favorites, looking for plants that require less maintenance.

Eddison writes about requiring a “standard of good behavior” for perennials. Her measure includes observing a perennial’s health, fortitude, and ability to withstand the extremes of summer and winter. They must be “well-behaved” and not invite pests. As plants age out, replace them with sizes and varieties that are easier to maintain. And, because climbing ladders is problematic as we age, choose low-profile trees and shrubs that are easier to reach for pruning and maintenance.

Pay Attention to Walkways
Every garden needs to be accessible and safe. Falls are problematic and can limit the ability to garden even more. Remove any places that may cause one to stumble. Eliminate a dip in a walking path and poor transitions between surfaces. Smooth pathways such as pavers, rather than woodchips or gravel, ensure ease for every gardener, particularly those who need the aid of a cane, walker, or wheelchair.

Herbs and lettuces can easily be grown in containers making it easy to gather when preparing a meal.

If the space doesn’t allow a large footprint, grow vertically with trellises in pots. Tomatoes are a beautiful addition, and can drive grown vertically with good airflow.
Be Amazed by What Can Be Grown in Containers
Life can throw us a curve, and home may change from acreage or a city lot with a garden to an apartment. Don’t let it rob the joy of gardening. When faced with gardening on a patio, containers can provide an excellent way to get a dirt fix. Most home gardeners are familiar with growing flowers in pots and containers. Many also successfully grow a wide range of vegetables, including tomatoes, beans, and kitchen herbs in pots. Depending on the space and container size, some folks even grow potatoes! The Vegetable Gardener’s Container Bible by Edward Smith provides advice for growing an abundant vegetable garden on your patio or balcony. Smith’s book is a stalwart in gardeners’ libraries because it is packed with information covering sun exposure, pot size, soil choices, and which varieties do best in containers.

Raised beds are also an excellent solution to making the garden user-friendly, making it possible to get your hands in the dirt without bending or kneeling. By keeping the beds narrow, 4′ or less, every inch of the garden is reachable from a standing or wheelchair position. It is incredible how much can be grown in a raised bed. With the popularity of raised beds, kits that only require simple assembly are available, or you can use the plans referenced later in this article.

Master gardener and adaptive gardening consultant Toni Gattone shares many adaptive gardening ideas in her book The Lifelong Gardener. Faced with chronic back pain, she searched for ways to adapt her northern California garden. She collected considerable wisdom about assessing limitations and finding joy in the changes. In the book, Toni profiles several gardeners faced with specific challenges and how they solved them with intentional choices and tools.

Gattone has a chapter about tools available for gardeners who face physical challenges. Scooters, carts, and ergonomically designed tools reduce some of the problems caused by aging joints. Long-handled hoes and weeders can make it much easier to garden from a bench.

Share a Gardening Space with a Friend or Join a Community Garden
Another way to garden without a home garden is to share a space. Many communities have garden spaces for people who need a place to garden. Whether in a community garden or sharing space in a friend’s garden, both offer the additional benefit of social interaction and shared knowledge.

See the Possibilities in Action
As spring turns to summer, you will find inspiration for adaptive gardening techniques in the Skagit County WSU Extension Master Gardener’s Discovery Garden on Memorial Highway (SR 536), west of Mount Vernon. Within the one-and-a-half-acre garden, local master gardeners have created an Enabling Garden, showcasing possibilities for people of all ages with limited physical abilities.

The Enabling Garden’s features include:

• Smooth ground surfaces
• Raised beds
• Resting places
• A display of adaptive gardening tools
• A selection of plants chosen for their sensory attributes or space

Rather than wood chips or gravel, pavers allow visitors with walkers or wheelchairs to move about easily. The raised bed design (8-foot x 4-foot x 1-3-foot) permits the gardener to reach every inch of each bed, standing or from a wheelchair. You’ll find more information about raised beds along with plans at https://www.skagitmg.org/raised-beds-2023/.

One raised bed features a sitting ledge to offer a rest from work. Another bed is designed for the visually impaired and features curved streams of small white rocks separating plant clusters and plants with different textures to touch and feel. A third raised bed is divided into three parts with cutouts to push in a walker or wheelchair.

A fourth raised bed features a vertical lattice panel in the center, supporting various runner beans and clematis. The panel, located in the middle, permits tending from both sides. Square foot gardening techniques are displayed in another raised bed where 24 one-foot squares, laid out with twine, show the variety and abundance of small vegetables, herbs, and flowers that one raised bed produces.

The coordinators of the Enabling Garden choose plants for their ability to satisfy the senses of smell, touch, hearing, and taste. Kids visiting this garden say, “It’s fun to feel” the wooly lambs’ ear (Stachys byzantina), spiky lemon thyme (Thymus citriodorus), saxifrage, trailing English ivy (Hedera helix), and soft moss that flourish in the bed designed for the visually impaired. Fragrant plants throughout the garden include lilies, mint, sage, violets, and sweet peas. Herbs like lavender, rosemary, and lemon verbena can energize the gardener. You will find plants included for their sounds, too! Balloon flowers (Platycodon grandiflorus), bamboo, Chinese lantern plants (Physalis alkekengi), and honesty (Lunaria annua) provide interesting and pleasant sounds.

Within the Enabling Garden, you’ll also find a display picturing enabling tools, showing the tool and explaining how it helps gardeners use less energy and work more effectively.

These tips only touch on surface ideas to make it possible to experience the rewards of gardening no matter what physical limitations a gardener faces. The resources below dig deeper into the possibilities for gardening at any age or ability.

Gardening for Wildlife

Thinking of adding new plants to your garden this spring? Choose from these recommendations to build a healthy ecosystem for your favorite wildlife species.

Updated: August 18, 2024

By: Joan D. Stamm, Skagit County WSU Extension Master Gardener

In a blog article last September, I recommended reading Nature’s Best Hope by Douglas Tallamy for the “why” of gardening for wildlife. This article will explore the “what” and the “where”-as in “what” plants and “where” to buy them.

For the “what,” I suggest Real Gardens Grow Natives by Eileen M. Stark as a guide to site prep, plant selection, and the benefits each plant offers the ecosystem. “Benefit” in this article, as in Stark’s book, is the critical word. It points to what the National Wildlife Federation (NWF) has coined as keystone plants.

What exactly is a keystone plant?
According to NWF, keystone plants are “native plants critical to the food web and necessary for many wildlife species to complete their life cycle. Without keystone plants in the landscape, butterflies, native bees, and birds will not thrive. 96% of our terrestrial birds rely on insects supported by keystone plants.”

Stark, a wildlife conservationist and landscape designer from Portland, Oregon, specializes in wildlife habitat gardens that include keystone plants. In the 317 pages of her beautifully photographed book, you will find 100 of her favorite Northwest native plant varieties and their many benefits for wildlife.

For example, the Garry oak or Oregon white oak (Quercus garryana) is one of the top keystone plants Stark promotes in her book. If we want butterflies in our garden, we need to have trees, shrubs, and perennials that host butterfly larvae. The Garry oak is one such tree; it is a host plant for many caterpillars, including the “gray hairstreak, California sister, and Propertius duskywing butterfly larvae.” In addition, the “flowers attract native bees,” and the “acorns sustain populations of mammals and birds such as woodpeckers, nuthatches and vireos.” “Studies show,” writes Start, “that oaks support more insect herbivores than any other plant genus.”

Although incredibly beneficial, not everyone has space for an 80-foot Garry oak. If not, consider another keystone tree: bitter cherry (Prunus emarginata). Birds such as “tanagers, waxwings, bluebirds, towhees, and flickers” will arrive to eat the fruit. A native cherry also hosts “swallowtail and Lorquin’s admiral butterfly larvae.”

If you love butterflies, another great keystone tree is Scouler’s willow (Salix scouleriana); it hosts “western tiger swallowtail, great comma, dreamy duskywing, and mourning cloak butterfly larvae.” In addition, native willow flowers “provide pollen and nectar for bees,” and “small and large mammals feed on buds, leaves, and seeds.”

Serviceberry (Amelanchier alnifolia) is also a keystone tree, providing “pollen and nectar for large numbers of bees, as well as hummingbird and spring azure butterflies.” Serviceberry fruit, says Stark, “is relished by waxwings, chickadees, woodpeckers, and tanagers,” and it is a host plant for “pale swallowtail, brown elfin, Lorquin’s admiral, and California hairstreak butterfly larvae.”

Along with these important native trees, many keystone perennials can fit into any open sunny space in your garden. A beneficial plant throughout many regions, goldenrod (Solidago canadensis), is a “nectar source for native bees and butterflies, such as the checkered skipper, clouded sulphur, gray hairstreak, monarch [east of the Cascades], and the endangered Oregon silverspot.”

Douglas aster (Symphyotrichum subspicatum) “provides nectar and pollen for bees and nectar for woodland skipper, pine white, painted lady, red admiral, mourning cloak, and the Oregon silverspot.” It is also a “host plant for field crescent and other butterfly larvae.”

Big-leaf lupine (Lupinus polyphyllus) not only “provide[s] pollen for native bumblebees,” it is a “host plant for silvery blue, painted lady, and orange sulfur butterfly larvae. Aphids attracted to the plant are preyed upon by syrphid fly larvae. Seeds are eaten by birds such as sparrows and finches.”

The Viola adunca, a native violet in our state, is a dynamic host plant for at least seven species of butterfly caterpillars and an enticing nectar plant for the endangered Mardon skipper butterfly.

Stark divides her native plant selections into three categories: plants for sun, partial sun, and mostly shade, guiding us in our creed “right plant, right place.” You’ll also find chapters on soil, pruning, watering, weeding, mulching, and much more. Her book is this gardener’s “go-to” choice whenever looking for the right native plant for a particular area and wanting to know the benefit to nature: what bees, butterflies, birds, or caterpillars the plant will attract.

As beneficial as all native plants are for our native wildlife, some natives on Stark’s list may not be suitable for an urban or suburban garden. For example, western red cedar, grand fir, Douglas fir, western hemlock, and Sitka spruce, are all enormously beneficial, but grow to a height of over 100 feet. The Douglas’ spirea, Stark warns, “may be too assertive for small, moist gardens.” Yet, the Spiraea betulifolia var. lucida, a small shrub with white flowers, might be perfect for a sunny border. Be sure to familiarize yourself with height, width, water requirements, and characteristics such as “vigorous,” “assertive,” or “rapid spreader” to determine if you have the “right plant for the right place.” A Nootka rose’s flowers and hips provide many benefits to wildlife but, over time, will grow into a thicket. However, if you have room for it to spread, it might make the perfect hedgerow, providing not only winter food for juncos and grosbeaks but also a habitat for nesting birds and the western checkerspot butterfly caterpillar.

For a more comprehensive book on creating gardens for wildlife, see Russell Link’s Landscaping for Wildlife in the Pacific Northwest. Link’s book not only includes extensive lists of native and non-native plants that benefit wildlife but also illustrates how to build habitats for birds, reptiles, mammals, and all the other creatures that make up a complete ecosystem. For example, he details snag locations and which draw native birds. He describes how to create a cavity in a live tree without killing the tree and thus create a habitat for a woodpecker. The book contains several kinds of fully illustrated brush or rock piles, including how to make them, where to place them, and who will benefit.

For example, Link says that “bushtits, chickadees, dark-eyed juncos, towhees,” and others “will use the inside of a brush pile,” whereas “hummingbirds, robins, and towhees will use the outside of a brush pile. Salamanders, snakes, toads, and turtles,” will use the base of the brush pile. He also covers how to create or construct proper birdbaths, ponds, nest boxes, and bat houses and features detailed drawings to illustrate how to build homes for Mason and bumblebees. Included are eight pages of colored photos depicting NW native mammals, birds, reptiles, amphibians, butterflies, moths, and other insects, describing our native birds and their preferred habitats.

With these three books, Nature’s Best Hope, Real Gardens Grow Natives, and Landscaping for Wildlife in the Pacific Northwest, you will be inspired, informed, and guided to provide plants that offer habitat and food (nectar, pollen, insects) for our native wildlife. You will better understand why it’s important to cultivate natives and have a clearer idea of what to plant, thus joining the movement to restore our natural ecosystem.

The only question remaining is “where” to buy all these wonderful beneficial plants?
You can start with our very own Skagit County Master Gardener Foundation’s Annual Plant Fair, which always features a native plant section. The sale occurs the Saturday before Mother’s Day (May 11, 2024) at the Skagit County Fairgrounds in Mount Vernon.

The local Salal chapter of the Washington Native Plant Society (https://www.wnps.org/salal-programs/garden) offers a twice-yearly native plant sale online with pick up at their demonstration garden adjacent to the Discovery Garden. Sign up to get email notifications.

Some of our local nurseries are beginning to carry more native plants. Azusa Gardens in Mount Vernon on Hwy 20 (https://www.azusagardens.com/) keeps expanding its native plant section each season. They feature two- and five-gallon shrubs such as twinberry, ocean spray, snowberry, red-twig dogwood, mountain hemlock, and others. Twinberry (Lonicera involucrata), in particular, is an attractive and beneficial native shrub easily grown with a little shade. It produces yellow tubular flowers attractive to hummingbirds and the berries are eaten by “thrushes, flickers, grosbeaks, and waxwings”; it’s also a host plant for the “snowberry checkerspot butterfly larvae.” Azusa also carries native ferns, and groundcovers such as bunchberry and wild ginger. They also welcome requests for specific plants.

Christianson’s Nursery in Mount Vernon on Best Road  (https://www.christiansonsnursery.com/) has a native plant section and carries one-gallon great camass (Camassia leichtlinii) in spring. They also have vine maple, salal, western red cedar, fir, hemlock, and kinnikinnick. The latter is a perfect groundcover. Kinnikinnick is not only evergreen, but the flowers are popular with bees and hummingbirds; the berries are eaten by “songbirds and many ground-feeding birds,” says Stark. It is also a “host plant for brown elfin and hoary elfin butterfly larvae.”

Plantas Nativa in Bellingham (https://www.plantasnativa.com/) specializes exclusively in native plants. They pack a lot of choices-conifers, shrubs, perennials, ferns, grasses, water plants, groundcovers, and more-into their small corner lot.

A little farther away but worth the drive, a visit to the Pacific Rim Institute (PRI) https://pacificriminstitute.org/ near Coupeville on Whidbey Island will reward you with not only a native plant nursery but a hike through a preserved segment of Washington’s native prairie landscape that contains the endangered golden paintbrush (Castilleja levisecta). PRI’s Nursery specializes in 50 native prairie plants. Many, such as woolly sunflower, red paintbrush, campanula, yarrow, larkspur, and fescue, will thrive in a sunny spot in your garden. Red paintbrush, in particular, is a beautiful, easy-to-grow native when planted with another native-like yarrow, woolly sunflower, penstemon, or blue-eyed grass. Due to its symbiotic nature, paintbrush requires nutrients from a host plant’s roots to survive. It blooms throughout summer, and Anna’s hummingbird loves the red flowers.

PRI also specializes in some unique native bulbs-ookow (Dichelostemma congestum), blue lily (Triteleia grandiflora), and harvest brodiaea (Brodiaea coronaria), that I hope will begin to replace my non-native tulips and daffodils for spring cheer.

With the knowledge and expertise of Tallamy, Stark, and Link, and a little help from our many plant retailers, you will be inspired to garden with native keystone plants that provide food and habitat for our indigenous birds, bees, and butterflies. In our age of endangered plant and animal species, we can be a force for eco-restoration right in our own backyard.

Gardening for Pollinators

A journey of learning

By: Patty Puckett Tingler, Skagit County WSU Extension Master Gardener

Pollen is a fine powdery substance, typically yellow, consisting of microscopic grains discharged from the male part of a flower. The term pollinator is not limited to wind, insects, animals, and butterflies. Some unexpected insects such as beetles and moths are also pollinators, performing the critical task of transporting pollen to the female parts of other plants, enabling fertilization and the production of seeds and fruit. Pollinators are vital to global crop production. According to an article published by the U.S. Forest Service, “Of the 1,400 crop plants grown around the world, i.e., those that produce all of our food and plant-based industrial products, almost 80% require pollination by animals.”

It is widely assumed that the honeybee is the predominant pollinator. However, there are many types of bees, solitary and social, and they all play a role in pollination. Typically, in a home garden, you’ll find solitary bees that are not part of a hive; however, all bees play a role in pollen distribution and pollination.

Flowers, Fruits, and Veggies

Gardeners should consider choosing plants that will provide pollinators with a variety of feeding choices all season long. Choosing early and mid-spring blooming flowers or bulbs to attract pollinators is a wise strategy. Once the pollinators have been attracted to the garden, vegetables will be bountiful all summer long. Fruit trees in blossom are ready to be pollinated. Be sure to share the bounty with birds later in the season as they were likely part of the pollinator team.

Remember to be patient. Attracting pollinators is laying the groundwork for years to come, so efforts made now will affect the garden and pollinators in the future. Watch and study your space for attractiveness to pollinators as you would for sun and shade. Neighboring plants can repel certain pollinators and you may need to move or rethink what to plant in a particular area to attract the pollinators for garden needs. Gardening for pollinators is a journey of learning and understanding.

Attracting Pollinators

If you personally like scented plants then you already know which plants pollinators enjoy. In addition to scent, think of using the open face of a flower as a landing place for the pollinator to rest while gathering and distributing pollen. Whether it’s a bee, a butterfly, or a bird, rest areas will encourage different pollinators to return. In the Pacific Northwest, especially western Washington, pollinators are lured by crocosmia, coneflowers, lavender, catmint, and sunflowers to name a few. One easy-to-grow pollinator-friendly annual is lacy phacelia, also known as blue tansy. It is a beautiful lavender color, grows easily from seed, and bees will flock to this plant. Distribute the seeds around your yard and enjoy its tall, beautiful splendor.

The number of scented plants in the Pacific Northwest is quite wide, from climbing vines like honeysuckle to lavender and lilac bushes. There are plenty of native species to choose from that are drought tolerant once established such as camas, lupine, salvia, and checker mallow also known as Malva. Daisies, asters, California poppy, catmint, and sage are also pollinator-friendly plants easily grown in the PNW.

What can we do to support pollinators?

How we can best support pollinators depends on the season. In fall, it’s best to put down your rake and leave the leaves on the ground. Mother Nature will do her best to push the leaves together under shrubs or against a structure. Some pollinators burrow under these leaf accumulations to overwinter. Wait until the spring weather is warmer (above 50°F) before cleaning up the garden as the pollinators will need the warmth as they emerge from their winter habitat.

Reduce the areas of grass on your property by adding shrubs, trees, and perennials that will provide visual interest and habitat for birds and insects. Use fewer toxins and chemicals, when possible. Pollinators need water for many purposes, including drinking, cooling, and reproduction so be sure to provide a source of shallow water near pollinator plants. Recycle pots or repurpose other containers (buckets, watering cans, birdbaths, etc.) on your patio or landscape to encourage more pollinators. Secondhand stores are full of items waiting for a reimagined purpose.

By providing backyard habitats or even a patio garden of scented, open flowers, bees and other pollinators will find your offerings. Support them by providing plants that help them do their job. Look online for native Pacific Northwest plants, shrubs, or seeds. Visit a local nursery to get plant recommendations or attend classes. Use your local library to learn more about creating or filling your garden with pollinator-friendly plants.

The more you learn about the world around you, the easier it is to live simply with our environment. Becoming aware of your environment and learning more about pollinators will open your eyes to the beauty and intricate connectivity of nature. We co-habit with and need insects, birds, butterflies, and other creatures to act as pollinators to plants to provide us with both beauty and nutrition. Our health, both physical and mental, would not exist without the efforts of the earth’s pollinators.

Help for the Vegetable Garden Novice

Tips every first-time vegetable gardener should consider

By Anne Hays and Cathy Markham, Skagit County WSU Extension Master Gardeners 

I am a vegetable garden rookie! There, now you know.

Some of us become gardeners later than others. I grew up moving from state to state just about every year. Our family’s unique military and government-dictated lifestyle left few opportunities for gardening growing up. As an adult, I found myself living in Alaska, spending 30-plus years tending fireweed, wild lowbush blueberries, and devils-club. Now, living in the abundantly beautiful Skagit Valley, I have the time and desire to learn how to successfully plant and grow a vegetable garden. As a novice, first-time veggie gardener, I turned to my wonderful friend and fellow Master Gardener, Cathy Markham, and asked her to mentor me through the process. The following is a journal of guidance and learning with the goal of a vibrant and bountiful vegetable garden this coming spring and summer.

Think Before You Leap

As both a gardener and a chef, Cathy has been growing a cook’s garden for many years. Both her Italian grandmother, on the central coast of California, and her mother, in the high mountain desert of Idaho, grew gardens. Cathy has never known a time when her family didn’t grow, harvest, and preserve.

Cathy advises working to get the most out of your garden space. When she teaches about gardening, she advises “Think before you leap.” Answer a couple of key questions such as “What do you want to take away from your decision to garden and what kind of commitment are you honestly willing to make regarding time, dedication, and hard work?” There are no wrong answers; it is just very helpful to define your expectations.

After many, many years of experience gained from multiple acres of gardens, and knowledge collected from gardeners who have gone before her, Cathy asks every novice vegetable gardener to consider:

Do you have a space that is prepared to plant? Is the soil in need of amending? Is there adequate water and is the sunlight appropriate for your garden space?

Is your space protected from deer, rabbits, or other animals that see your garden as a free salad bar?

Are you prepared to tend your garden frequently, checking for insects and disease, weeding, tending seedlings, and then harvesting for maximum yield?

Considering these questions will help you decide if “digging in” and starting a home vegetable garden is for you. In fairness, sometimes our lives or interests can’t support the commitment of growing a garden and it is better to support a local farm stand. Gardening is just not fun when you are constantly trying to keep your plants alive in poor soil and conditions, or when you are doing the added work of trying to keep the deer and rabbits out of your garden. If you are serious about getting a harvest for delicious eating and winter storage, the answers to these questions are important.

After listening to Cathy’s advice, considering her questions, and thinking through our commitment to becoming vegetable gardeners, my partner and I said “Yes! We are ready and committed to growing our own vegetable garden.”

This past fall, we set about building a garden space, installing six vinyl-clad trough-style raised beds which were ordered from an online source.

Opting to use drip irrigation, we installed the necessary infrastructure and then filled the six beds with commercially distributed topsoil. Placed next to the house on the south side, three beds measure 3.5 feet by 3.5 feet. Two beds measure 2.5 feet by 8 feet and one measuring 2 feet by 6.5 feet, adjacent to the square beds with a 6-foot path and workspace in between. We plan to attach hog-wire to the house wall for trellising above the three, square beds.

The investment, not including the raised beds, came to $539.63. Once everything was in place, we invited Cathy to visit the newly minted, naked garden. She thought the raised garden beds looked great; having the potential for lots of sun, available irrigation, and plenty of space for vertical growing! Cathy suggested getting started right away by planting winter veggies such as leeks, kale, and garlic as a first foray into the veggie gardening realm.

Rookie Alert: The eight garlic cloves purchased were about six more than most any household needs. Cathy happily adopted the surplus garlic for her garden. Then she quietly pointed out that the leeks, which by then, looked more like bunches of scallions, needed to be separated from their clumps to grow with adequate space. Who knew?

The Next Step – Planning What to Grow
Here again, Cathy’s advice, based on years of experience and research-based learning, was invaluable-she helped us decide what to grow; when to grow; and whether to buy starts versus seeds. Her advice is to grow what you love to eat. Okay, then not so many cukes since my partner is not a fan. Cathy recommends a wonderful book: Grow Cook Eat by Willi Galloway as a starting point for garden planning.
Starting with Seeds Versus Buying Plant Starts
Locally grown plant starts are a reliable way to get up and running. But spending time with seed catalogs is enthusiastically encouraged! Some favorites are provided in the references below.

The next steps will include getting together during the cold and dark winter months for tea or warm cider to go through seed catalogs and map out the garden planting. Raised bed experts recommend growing tomatoes on a trellis, and weaving in other climbers, such as beans, on the same trellis to efficiently utilize the space. It is key to plant at the right time – don’t start too early!

Here are some of the guiding principles Cathy encourages new gardeners to lean on:

Grow what you love to eat.

• You have a lot of choices for what to plant in your vegetable gardens but the best choices are the ones you or your family are actually willing to add to your diet and eat. You are more likely to put the work into the garden and harvest for foods you love to eat.

Start small and be successful with easy-to-grow plants.

• A very small garden can be very productive and rewarding. It gives you a chance to experiment with plants, maybe one tomato plant or eggplant. Greens, bush beans, cherry tomatoes, carrots, and herbs are an easy way to start. Choose bush and dwarf varieties for small spaces so you won’t have to worry about staking. If you have vertical space, climbing vegetables are great; these include peas, beans, cucumbers, indeterminant tomatoes, and now several new varieties of squash have been developed which grow vertically in small spaces.

Grow nutrition-rich and versatile choices.

• Adding nutrient-dense vegetables to our diet is always a plus! Dark leaved greens like kale, spinach, and chard; rich dark root vegetables like beets and carrots; peas and beans, garlic, onions, leeks, and shallots; broccoli or broccolini; and tomatoes!

Grow what is expensive to buy or is not as flavorful when you buy it.

• This is especially true of herbs which are easy to grow for the most part and make a huge difference in food preparation. Tomatoes and English peas (shelling peas) are examples of vegetables that are so much better fresh from the garden. Potatoes and corn are plentiful and readily available, so you may choose to skip giving up the space it takes to grow them.

Decide what “mountains to die on.”

• Based on your time and patience, decide what you are willing to deal with in your garden. For example, you may choose not to grow many vegetables from the cabbage family because you are not willing to deal with the bugs and worms that they attract. You may choose instead to grow broccolini, a short, early-season vegetable, or maybe Kalettes (a cross between kale and Brussels sprouts) because they are fun. You can buy what you choose not to grow at a farmer’s market.
• We live in an area where an excellent choice of vegetable starts is available. If you have a new garden, this is a big boost to success because you don’t have to deal with the germination of seeds. Beans are the exception here, they do best when grown from seed. The plus for growing from seed is the huge variety of available seed sources. This may not be a priority for new gardeners.

Grow organic as much as possible.

• The better you take care of your garden the less you will need to use any chemicals on it. Keep the garden clean of weeds, and mulch to keep the weeds down and the soil moist. Keep the pathways clean also; weeds and grass are very difficult to manage when they grow big. It is easier to pick them small, not letting the weeds compete for nutrition. Thinning your growing plants appropriately will cause them to grow strong and able to survive the normal garden bugs. Use a foliar spray made of a mix of kelp concentrate and fish emulsion for fertilizing. Water the plants consistently so they do not become compromised and weak, which leads to disease.

Begin at the right time – don’t start too early.

• It is so tempting to get the seeds or plants in the garden early. The first sunny day seems warm enough – surely we are done with the cold weather! Garden success comes from resisting this temptation. It isn’t a competition with anyone else, or a race to see who can get the earliest peas. Take the time to prepare the gardens, clean out the flower beds, and pace yourself. This may not suit some, but except for garlic, which gets planted in late October, and leeks and shallots in March, planting can wait until April for the cool spring crops, and everything else until mid to late May. Wait patiently until late May and or even early June to plant tomatoes, eggplant, peppers, and tender herbs like basil. Until the soil is warm, so many plants just shiver and sit. But if you wait until the soil is warm, seeds will germinate quickly and plants are stronger. A compromised plant may not ever get back the vigor of one that has not been traumatized by the weather!

Commit to what you start, that is – take care of your garden. And have fun!
As winter turns to spring, we will meet, talk, plan, and put these guiding principles into action. We plan to continue with a follow-up blog post in spring to report back about our plans and decision process. We promise, you’re going to want to learn more about our garden pest-repelling strategies.

Turn the Dark Days of Winter into a Spring Planting Advantage

Start an indoor grow stand and you’ll be enjoying homegrown salad before you know it

By Kay Torrance, Skagit County WSU Extension Master Gardener

The Pacific Northwest offers unique challenges for gardeners. In the fall the endless summer comes to an abrupt end, with daylight decreasing over three minutes a day from mid-August into early November. As the winter solstice arrives on December 21^st there are only 8.5 hours of daylight. We can’t change that, so let’s start a project. 

Want to grow herbs and vegetables in the middle of the winter? Want to get a jump on spring gardening by starting vegetables indoors to plant outside after the last frost? Do it with an indoor growing stand. It can be as simple as hanging a light from the ceiling and placing a few trays on a table. Prefabricated kits are available in all shapes and sizes, or build your own. Many Master Gardeners use their grow stands year-round. In the summer it is great for starting fall vegetables, and flowers, or to protect tender plants such as basil from outdoor insects and slugs.

Find a Suitable Location
Gardeners naturally want to place their grow stand near a window. However, with good artificial lighting, you can use a dark corner, unused room, or heated basement. Unused kitchen counters or shower stalls also work well.

Grow stands look tidy, but you are working with dirt and water. Locate them away from carpets and wood floors. Office chair mats work well to protect delicate floors. Hang a white shower curtain behind the stand to keep the wall clean and reflect light. If you are setting the stand on a table, use a vinyl tablecloth. For wood tables, make sure the trays are not touching the wood as the heat and humidity will damage the finish. Locate the stand near a power source for the lights and heating pads. Plants add moisture to the air, so make sure you have good ventilation to keep you and the plants healthy.

Sizing Up Your Stand
Think about the size needed to match your growing goals. 3.5-inch square pots often work well as a final size. Once the plant outgrows the 3.5-inch pots, the plant is either harvested or ready to go outside. The most common greenhouse tray size is 10 by 20 inches, commonly called a 1020 tray. One tray holds 18 3.5-inch pots, or 12 6-plug trays (72 plugs total), or eight 5-inch pots. If you only have room for one tray, herbs are a great choice. If you have two trays, lettuce, spinach, fennel, and microgreens are good options. If you have four trays, you have room for a dedicated seed starting tray, while the other three trays are staggered to produce enough salad to feed two people.

Once you have an idea of the size, it is time to decide whether to purchase a kit or build your own. If you decide to purchase a kit, there are many options available; some fit on a small tabletop, others are large tents that are mini-indoor greenhouses. Save money by repurposing shelving and lights or by building your own out of pipe or wood.

Building a DIY Grow Stand
The easiest way to get started is to hang a grow light from the ceiling, throw a vinyl tablecloth over a table, and put up a section of shower curtain to protect your wall if needed. Add a heat pad and you are ready to go. Hanging lights from the ceiling gives the most flexibility for lighting with unlimited options for height above the plants. If you don’t want holes in your ceiling, a lighting support can be built using shelving, or a frame from PVC, metal conduit, iron pipe, or wood. Think about things you already have that can be repurposed. Sawhorses or a six-foot ladder can make a good light stand support.

PVC is easy to work with and has lots of joint options. If you search online, many design plan options are available. Some guidance recommends against using PVC cement on the joints so the racks can be easily disassembled for storage; however, this can result in a wobbly stand. One alternative to gluing is to drill a small hole in the joint and insert a screw.  This allows for disassembly but does not allow pieces to come loose while you are using the stand. (PVC does not accept most paints so don’t expect to hide the bright white pipe with paint.) Using threaded metal plumbing pipe creates a heavy/sturdy stand with a steampunk look, but the pieces are more expensive than PVC. Threaded metal pipe is available in many lengths so you don’t have to cut it. The threads make for easy assembly. Metal pipe can be painted, and you can disassemble it for storage.

For shelving, plywood is readily available and sold in small pieces, called project panels, at home improvement stores. Often, stores will make cuts for you. Use at least 5/8-inch-thick plywood because thinner pieces will sag over time. Countertop remnants are a sturdy and waterproof alternative. I have found that two-inch foam board insulation panels are easy to use. These panels are inexpensive, lightweight, and can be cut with a utility knife. They are also waterproof, and are available in two-foot by two-foot precut panels, which will hold two 1020 trays. Foam board can also be used on a tabletop to protect the surface from heat and moisture emitted from the heat pad and trays.

Selecting Lighting for Your Grow Stand
Grow stands need a good source of artificial lighting, ideally lights that produce a full spectrum of high-intensity light for rapid plant growth. Leafy greens and herbs need around five hours of direct sunlight each day. Most garden vegetables need up to 14 hours of light each day.

Fluorescent or LED tube lights are an inexpensive alternative to a plant or grow light. Florescent lights give off some heat, which is beneficial to plants, but the glass bulbs can be easily broken. LED grow lights produce the highest intensity light but are the most expensive. They are also more energy efficient and rated for long life. Incandescent lights are not a good choice because they use much more energy and generate a lot of heat which can dry out leaves.

Setting Up the Lighting
Fluorescent lights should be hung one to three inches above the plants. The tubes need to fully cover the plant trays. Choose a fixture with four to eight bulbs or mount multiple fixtures side by side to ensure coverage. Fluorescent bulbs sold for home lighting are not as intense as grow lights and will need to be turned on longer each day. Plan on 8-10 hours of light a day for herbs and leafy greens, and 12 to 14 hours for vegetable starts if you are using fluorescent lights.

LED grow lights are placed 10 to 30 inches above the plants. Follow the manufacturer’s directions. Box-shaped LED grow lights are easy to work with. The added height of the light above the plants increases the overall height of a grow stand; however, it is easier to water and tend plants without moving trays. Plan on six hours of light a day for herbs and leafy greens and eight to ten hours for vegetable starts. When selecting an LED grow light, be mindful of the color of the light. Blues and reds are great for plant growth, but if your stand is in the living room, you might not enjoy being bathed in a purple glow.

Experiment and adjust the height of the lighting and duration based on your specific setup. All lights generate some heat. Make sure the lights have adequate clearance per manufacturer’s directions and keep an eye on your plant growth so the plants don’t grow into the lights. When purchasing lights, compare all the features. Some fixtures have outlet plugs for connecting multiple lights. Some of the grow lights have built-in fans which keep the lights cool and provide some air circulation for the plants. The fans do generate noise.

Heating Pad Selection and Use
Make sure to size the pad to cover as much of the footprint of the plant tray(s) as possible. Place the plant tray on top of the pad. Do not put the pad inside the tray with the plants directly on top of it as the pads are not designed to be in direct contact with water. Often heat pads are sold rolled up in boxes. At room temperature, the pads are stiff. Before unrolling a pad, plug it in and let it warm up. Forcing them flat can break the heating elements inside.
Trays, Domes, and Pots
Using standard 1020 greenhouse trays makes pot sizing easy because many pots sold are designed to fit in the trays. Select the trays without holes in the bottom. Use a dome (plastic cover) for starting seeds.  If seeds dry out during germination, it will kill them. Use 6-pack cells to start the seeds and 3½-inch pots after the plants outgrow the cells. When starting vegetables with large seeds like squash or cucumbers, begin with 3½-inch pots. You may want several small trays if you are growing microgreens. It is important to sterilize trays and pots if you are reusing them.
Growing Media and Fertilizer
Always use sterilized growing media. This will help prevent dampening off as well as fungus gnats. Use a water-soluble fertilizer designed for vegetables per the manufacturer’s directions.

Important Safety Considerations:

• Hang lights with appropriate clearance following the manufacturer’s recommendations.
• Make sure lights are properly supported. If you are attaching eye bolts connected to the ceiling, make sure they are affixed to the ceiling beams and not just into drywall or other materials where the screws could pull out.
• Make sure to use UL rated lights, heat pads, and surge protectors.
• Make sure that any electrical components that require grounding (3-prong plug) are properly grounded.
• Protect wood surfaces from heat and moisture or you can ruin the finish or warp the wood.
• If using shelving, attach the shelving to the wall so that the stand isn’t accidentally knocked over.

Accessories to Make the Process Easier
Adding a timer to your lighting to ensure consistency is highly recommended. Even the most organized gardener will forget to turn on or off the lights sometimes, especially if the grow stand is located in a basement or out-of-the-way area. Make sure the timer accommodates the three-prong grounded plugs used by plant lights. Some timers are also surge protectors with multiple outlets controlled by the timer. The heating pad needs to be plugged into an outlet, not on a timer. A small oscillating fan provides good ventilation, reduces fungal problems, and the motion helps strengthen the plant stems as they grow. A set of pulleys allows quick and precise adjustments to the height of the lights.
Selecting What to Plant
As a rule of thumb, plant what you like to eat. However, avoid vegetables that take a long time to grow, keep well, and are inexpensive to purchase. Concentrate on herbs and greens that are best eaten fresh. For detailed information and a planting calendar, read the WSU Home Vegetable Gardening in Washington for help selecting vegetables, learning how to harden and transplant starts, and growing them until harvest.

If you are growing plant starts to transplant outdoors, start seeds around eight weeks before the last frost date. Per WSU AgWeatherNet, the last frost for Skagit Valley is generally in May, so March is a good time to plant indoors. Temperatures in many areas vary due to micro-climates, so experiment to see what works for you

Starting Seeds
Plant each 6-pack with the same or similar seeds. Some plants like parsley will stay in the 6-pack for four to six weeks whereas lettuce will need to be transplanted in two to three weeks. Twelve 6-packs will fit in one 1020 tray – that is 72 plants! It is easy to get carried away and outgrow your grow stand. Think of how many of each plant you want. You may only need two parsley plants but a dozen lettuce plants. Plants grow at different speeds. Check days to harvest on the seed packets. For each tray, I will usually plant three 6-pack (18 cells) that will grow into 18 four-inch pots. I use small trays to plant microgreens to fill the remaining space as they will be harvested before they need to be moved to larger pots.
Transplanting and Harvest
It will take 5-14 days for seed germination. Some seeds will germinate faster if you soak them in water first. Follow directions on the seed packet and research specific germination information from various seed companies. Growth rates will vary based on your temperature, light, and fertilizer. The young plants should be ready to transplant to 3 1/2-inch pots around three to five weeks from germination. If you are unsure if your starts are ready for a larger pot, carefully pull one plant out of the container and look at the roots. Parsley and spinach seem to take forever whereas lettuce, Bok choy, and tomatoes grow really fast. Look for well-formed roots starting to emerge from holes in the plugs or pots.

When harvesting, take only what you need for a meal and leave the rest on the plant, using the come-and-come-again method. Harvest the older/outer leaves leaving the young leaves for later. This provides enough foliage to keep the plant healthy and prolong your harvest time. When the plants become too big for the 3.5-inch pots, it is time to transplant them or harvest all the leaves and start over. It is great to stagger crops so you are always in fresh greens.

Gardening with Raised Beds

Raised Beds Provide Many Advantages to Home Gardeners

Editor’s Note: 
As the daylight hours continue to wane, many gardeners turn their attention to planning for next season. Some of us even have a Christmas wish list which has been known to be filled with tools and even projects that will enhance our gardening endeavors. For this reason, the Ask a Master Gardener Blog editors are reprinting a favorite article, complete with plans, a materials list, and updated references which answer one of the most asked questions at plant clinics and market kiosks —“How do I build a raised bed garden?”

_  _  _ 

By Dave Buchan, Skagit County WSU Extension Master Gardener

Want to grow better vegetables but concerned about poor soil quality in your garden plot? Are you frustrated with continually trying to amend your soil for better growing but getting nowhere? Do you have site conditions or drainage problems that prevent establishing a good garden? Your solution might be gardening with raised beds.

What is a Raised Garden Bed?
A raised bed is really nothing more than a device containing a vertical column of quality soil to create the best possible growing conditions for your garden. Raised beds can vary greatly in size, but typical garden beds are generally 12 to 24-inches in height and about 4-feet in width. Your ideal width may vary, but a 4-foot width is a dimension that most gardeners use because you can easily tend half the garden from one side, and then the other half from the other side. Length can vary depending on space and site conditions. Some gardeners choose raised beds up to 16-feet long.
Why Use Raised Garden Beds?

Raised beds offer many advantages for gardeners. Most importantly, raised beds allow you to control the quality of your soil. Soil quality is the number one consideration for successful gardening. The second major advantage of raised beds is that you can garden without getting down on your hands and knees to tend your garden. For older gardeners, this is a real benefit and can make gardening more fun. Placing a wood or metal “seat rail” on top of each side of the raised bed allows you to sit on the edge of the planter for easier weeding or tending.

Another advantage with raised beds is that with bed sidewalls exposed to the sun, soil temperature in the beds can be slightly higher than with a normal garden. And surprisingly, a simple degree or two in soil temperature can make a big difference in the growth of your plants.

Other benefits of raised beds are that: (1) vegetables can be planted a bit closer together and thereby a better yield per square foot of garden space, and (2) raised bed soil will not be as compacted as normal garden soil. There are no rows between plants that are walked on and no wheelbarrows traveling over to compact the soil. Less compaction means more fertile soil for better plant growth.

What Types of Raised Beds are Commonly Used?
Raised beds are made from many materials: stone, concrete block, concrete riprap, treated or plain lumber, galvanized steel panels, railroad ties, and more. Whatever material is used the structure needs to be strong and durable. You can imagine that a well-watered 18 to 24-inch high column of soil carries a lot of weight, especially laterally. So, your “container” needs to be strong enough to support that soil weight. If you’re not too handy, there are raised bed kits available online and in some box stores. These kits can vary in quality and durability, so take care choosing a unit that will work for the long haul.

If money is no object, you can buy commercial galvanized steel feed troughs as your raised bed. They come in a variety of sizes and are sturdy, good-looking, and will last years. Simply drill a series of ½ inch holes in the bottom for good drainage and VOILA! -a great raised bed.

More likely, you will choose to make your raised beds using materials that are commonly available from local stores or surplus outlets, such as treated or kiln-dried lumber, concrete block, concrete riprap, stone, or galvanized steel panels.

Material Considerations
Concrete block: Concrete block can make a good raised bed, but you need to be prepared to spend some time tweaking and adjusting rows of blocks. You need to start with a level site. Blocks are heavy to work with and even a slight change in ground level on the first row can translate to a bigger problem on the second row. This requires patience and some determination to get it right.

Stone or riprap concrete: If you have a supply of stone or riprap to use, great. But this can be heavy work and you need to be careful with stacking stone or concrete to create a solid structure that will last.

Treated or kiln-dried lumber: All wood will eventually rot, even treated wood. Whenever wood is in contact with soil, wood will begin to deteriorate. Especially at today’s lumber prices, you want your investment in a raised bed to provide years of reliable service. There are techniques to add to the life of wood used in raised beds, which are discussed in the website materials described below. Caution: Chemicals used to treat lumber can leach into the soil and contaminate the plants being grown.

Corrugated galvanized steel panels: From both a cost and durability perspective corrugated galvanized steel side panels with treated wood corner posts and treated wood seat rails are sturdy and long-lasting. The steel panels are lightweight and easily cut with metal shears, skill saw or jig saw with metal cutting blades. These materials are available at almost any hardware or box store. The galvanized steel sidewalls will last many years and will not leach chemicals into the soil as can some treated wood. Placing a treated 2-foot by 6-foot board horizontally across the top of each sidewall creates a handy seat for use when weeding and tending your garden.
