5 Favorites: Cold Frames to Warm Up the Garden

A simple cold frame keeps seedlings warm when the garden is frozen. The baby lettuces will love you for it.

As humble as many of these mini-greenhouses may look, cobbled from bits of scrap wood and salvaged windowpanes, cold frames have an amazing ability to create micro-climates. You can buy a ready made one (see “10 Easy Pieces: Cold Frames“), or build your own in an afternoon, following Martha Stewart’s meticulous step-by-step instructions. Better make that two afternoons.

Or wing it, with an old piece of glass and some two-by-fours, because as the garden writer Henry Mitchell once put it, “it is more important for the gardener to be enchanted than for critics to be pleased.”
