Cold Frames

Cold frames are simple, low-profile growing structures that provide a protected environment for plants without the size or complexity of a greenhouse.  At The Greenhouse Shop, we offer cold frames that are ideal for gardeners who want to extend the growing season, protect young plants from harsh weather, and give seedlings or cuttings a head start before they go into the garden.

A cold frame typically consists of a transparent lid or cover that lets in light while trapping warmth from the sun.  This creates a sheltered microclimate that stays warmer and more stable than open air, making cold frames perfect for raising seedlings early in the season, hardening off young plants, or overwintering tender varieties.  They’re also great for herbs, salad greens, and root crops that benefit from gentle protection.
