Winter Garden and Season Extension Learning Hub
Welcome to the Winter Garden & Season Extension Learning Hub, your practical guide to gardening year-round—no matter how cool the weather gets. Drawing from more than three decades of four-season gardening in Sonoma Valley, as well as several years gardening in Iowa’s Zone 5 winters, I share the methods, tools, and timing that keep beds productive from the first fall frost through early spring. Here you’ll find straightforward, experience-tested advice on preparing beds, choosing crops, protecting plants, and building soil health through the winter months. Whether you want fresh harvests all winter or simply aim to start spring with stronger, healthier soil and earlier crops, this hub brings together the strategies that truly work in a home garden.

My Experience: Why This Hub Exists
This hub grows out of a lifetime of year-round gardening—first in the mild but unpredictable winters of Sonoma Valley, and earlier in the deep-freeze winters of Iowa’s Zone 5. I’ve spent more than 30 years testing methods that keep vegetables growing through cold nights, short days, and wet soil. Over time, I’ve refined techniques that work in raised beds, mounded beds, and containers, always guided by the NEW method—Narrow bed, Equidistant planting, Wide rows—and by a commitment to simple, regenerative practices. This hub exists to share what I wish I’d known when I started: that with the right planning and protection, a winter garden can be incredibly productive, resilient, and enjoyable. My goal is to help you avoid guesswork, build confidence, and grow food through every season of the year.
