Cold frames are ideal if you are sowing seeds, raising cuttings, or growing tender plants that will benefit from a bit of protection during the colder months. They come into their own if you don’t have space for a greenhouse, too.
Spring is a busy time for growing under glass, and using a cold frame now will allow you to get peas and beans off to an early start or harden off tender young plants, ready for the summer months. It will also extend the growing season over the autumn and winter, looking after cuttings ready for the new year and nurturing newly sown hardy annuals - for added protection through the colder months find out how to insulate your cold frame.
Whether you’re looking for wooden cold frames from sustainably sourced timber or something a little more modern, you’ll find just what you need in our pick of garden cold frames.
