In cold frame gardening, a cold frame is a simple structure that usually works like a mini-greenhouse. It has a wooden frame with a transparent roof made from glass and is always constructed low to the ground to provide proper insulation.
Cold frames are permanent structures that considerably lengthen the growing season. They are an excellent way to grow fall and winter crops. Cold frames provide protection from strong winds, elevate the daily and nighttime temperatures around the plants, and protect frost sensitive vegetables or flowers. They are easy to build and the vegetables and flowers in them will require minimal care.
