Fall may feel like the end of the gardening season, but for many spring-flowering plants, it's just the beginning.

In this episode of The Evergreen Thumb, Erin explores fall planting in Washington, with a focus on spring-flowering bulbs and other geophytes. We'll look at why fall is the right time to plant many of these plants, how soil temperature affects planting timing, and what Washington gardeners should consider when deciding when to get their bulbs in the ground.

We'll talk about familiar garden favorites such as daffodils, tulips, and hyacinths, along with some less familiar native geophytes, including camas and fawn lilies for seasonal interest and to support regional biodiversity.

Cover crops can protect and improve garden soil during the time of year when our gardens are resting. In this episode, Erin talks with Twinflower Wilkie, a WSU Extension Master Gardener in Ferry County, about how cover crops help retain moisture, protect soil from erosion, cycle nutrients, and build healthier soil.

Twinflower also shares why cover crops can benefit pollinators and other beneficial wildlife, and why allowing your garden to go a little wild can be good for the garden and the creatures that depend on it. They discuss choosing and using cover crops in the home garden and simple ways gardeners can get started.

For gardeners in Washington's dry eastern climate and beyond, cover crops offer a practical way to keep soil protected and productive while creating a more welcoming garden for wildlife.
