Autumn is a great time to refresh your garden soil in preparation for next season. Join us for "Soil Nutrition 2.0," a free in-person work shop at Bellevue Demonstration Garden on Saturday, October 3, 10 a.m. Presented by Karen Adams, WSU Extension Master Gardener, this workshop will focus on managing and improving soil tilth for both vegetable beds and ornamentals. Healthy soils produce nutritious foods, strong plants and protect the environment. Learn about various soil amendment uses and benefits, specific crops and their unique needs throughout the growing season, and how to protect soil biodiversity with organic methods. BDG In-Person Gardening Workshops are held in the covered shelter at Bellevue Demonstration Garden near the Lake Hills Ranger Station unless otherwise indicated. Presentations last between 45 and 60 minutes, some followed with a 30-minute demonstration or hands-on experience.

🍁 Let the Rain Do the Watering: Plant a Native This Fall 🍁

The autumn equinox has come and gone, and if you think of spring as "planting season," here's a nudge to think again. Fall is one of the best times of year to put a native tree, shrub, or groundcover in the ground, especially in those corners of the yard your soaker hose or sprinkler never reaches.

🌧️ Why fall?
• The soil is still warm while the air cools, so plants put their energy into roots rather than new leaves.
• Our fall and winter rains do the watering for you.
• Roots keep growing through the cool, wet months, so by spring your plant is ready for our drier springs and hot summers. A spring-planted shrub meets its first dry spell with only a few months of roots.
• You have time! You can plant any time the soil is workable (not frozen or waterlogged) into early winter. Earlier is better, though. October is ideal.

🐝 Why natives?
Our native plants evolved with our wet-winter, dry-summer climate. Once established, they need little extra water, and they feed and shelter the local food web: early nectar for native bees, berries and seeds for birds, host plants for butterflies, and cover for wildlife.

🌿 Water-wise natives to try

Sunny and dry:
• Oceanspray: arching shrub with creamy flower plumes; hardy and drought tolerant.
• Red-flowering currant: chains of pink flowers in early spring, a hummingbird magnet and an early meal for native pollinators.
• Mock orange: fragrant white blooms; handles moist to dry soil.
• Serviceberry: white spring flowers, then sweet, edible berries (if the birds leave you any).
• Tall Oregon grape: holly-like evergreen leaves, bright yellow spring flowers for native bees, and blue berries for birds. Tough in sun and dry soil.
• Kinnikinnick: low evergreen groundcover for well-drained sunny spots; red berries for wildlife and great for erosion control.

Shady and dry (hello, spot under the big tree):
• Vine maple: small tree with brilliant fall color and seeds that feed wildlife; part shade to shade, dry to moist soil.
• Indian plum (osoberry): one of the first shrubs to bloom each spring, a lifeline for early pollinators.
• Evergreen huckleberry: glossy evergreen shrub with pink spring bells and sweet late-summer berries (share with the birds!). Likes acidic, well-drained soil; slow to start, but worth the wait.
• Salal and low Oregon grape: tough evergreen groundcovers for woodland spots. Birds love both of their berries.
• Sword fern: the classic PNW fern, happy in dry to moist shade.

Adaptable to almost anything:
• Cascara: small tree for sun to shade and dry to wet soil; shiny leaves, fall color, and berries birds love.
• Snowberry: sun or shade; white berries hang on into winter for the birds (not for people!), and its spreading roots help hold soil.

💧 One honest caveat: "drought tolerant" means once established. Water deeply at planting, mulch (keeping it a few inches off the stems), and give a deep soak during long dry spells in the first summer or two.

Fall garden tip: Mulch!
🍂🌿🪏🌱✨
Fall is a fabulous time to apply mulch to garden beds. Mulches are materials added on top of soil and can include wood chips (or arborist chips), compost, shredded leaves, hay, grass clippings, and cardboard. Cover crops are sometimes called "living mulch."

🍂There are boundless benefits of mulch including suppressing weeds, conserving water, protecting soil from extreme temperatures, adding nutrients, and beautifying garden beds.

🍂Before mulching it's good to do a little tidying to remove weeds, diseased fruit, or moldy leaves to help prevent unwanted stuff from coming back next year.

🍂Using a method called "sheet mulching" or "lasagna gardening," lawn areas can be turned into garden beds. The simple steps are laying cardboard down, wetting it, then adding a thick layer of compost or wood chips. By spring, a patch of grass transforms into a nutrient rich soil ready for plants!

Enjoy the magic of mulch! Happy fall gardening.🍂✨
