Companion planting is a valuable technique for winter gardening, helping crops grow stronger, resist pests, and maximize space. From my experience growing vegetables in Iowa’s Zone 5 winters to year-round winter gardening in Sonoma, pairing compatible crops under tunnels or cold frames improves yields and overall plant health.

Structures like low tunnels, caterpillar tunnels, and cold frames are excellent tools for extending your growing season, protecting crops from frost, and creating microclimates for winter vegetables. However, even in winter, these structures can overheat on sunny days, potentially stressing or damaging plants. From my Iowa winters in Zone 5 to year-round winter gardening in…
Extending the growing season is one of the most effective ways to increase reliability and productivity in a home vegetable garden. Three simple structures—low tunnels, cold frames, and caterpillar tunnels—can protect cool-season crops from frost, freezing temperatures, wind, and heavy rain. Each structure has its own strengths, ideal climate range, and best crop uses. Visit…
Growing vegetables through winter is absolutely possible in zones 5–8—you just need the right protection. Low tunnels and cold frames create a warmer, more stable microclimate that keeps cold-tolerant crops alive and growing even during freezing weather. After years of winter gardening, I’ve found that protected structures are the key to steady greens, crisp roots,…
A cold frame can extend the growing season, either in spring or autumn. A cold frame is a sturdy, open-bottomed box with a glass or plastic lid that lets sunshine in but keeps the cold out. Sunlight trapped in the closed box heats the air and soil inside allowing plants to thrive. In spring, cool-weather…
A cold frame is a bottomless box with a clear or translucent top. It is set on the ground or over a planting bed to capture solar energy and heat the air, soil, and plants inside. A cold frame can extend the growing season by one to several months. A cold frame can keep plants…
