Cold frames are a great gardening accessory, giving you a place to harden off transplants before putting them into the garden, giving seeds a head start in germination just before the last frost, and giving warm weather crops — tomatoes, peppers, eggplants — a warm boost when the days and evenings might still be cool. In general, they’re a great way to extend the growing season from either end, spring and fall. Building one is simple. Resourceful gardeners make them from scavenged wood and reclaimed window sashes. But you can also build them from scratch, allowing you to use materials that will better withstand the elements while putting your woodworking skills to use. And, of course, you can buy them as kits.
