The Evergreen Thumb

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.

In this episode of The Evergreen Thumb, Erin Hoover chats with Julie Banken, a Master Gardener with a background in entomology, about creating pollinator-friendly gardens by rethinking traditional fall cleanup practices. Julie shares her passion for gardening with insects in mind, explaining how leaving leaves, stems, and other natural debris provides essential winter habitat for a wide variety of pollinators and beneficial insects. She encourages gardeners to view their yards as crucial parts of the ecosystem, highlights the importance of native plants, and offers practical advice for supporting insect life cycles—like leaving leaf mulch and standing stems through winter and only tidying up the next year. By making simple intentional changes, gardeners can help sustain the pollinators and insects that depend on them, making a positive impact right in their home gardens.

Every gardener has decisions they would make again…and a few they probably wouldn't.
In this episode, Erin Hoover reflects on the gardening choices that paid off, the ones that created more work than expected, and the unexpected surprises that have shaped her garden over the years. From self-seeding herbs that got out of control to volunteer flowers worth keeping, she shares practical lessons learned through trial, error, and observation.
Along the way, Erin discusses why investing in quality seed potatoes and garlic has been worthwhile, how redesigning her vegetable garden improved watering efficiency, and why a simple moisture meter completely changed the way she waters her garden.
If you're just starting out or even if you are a seasoned gardener, this is a reminder that every season teaches us something new.
