Using your cold frame in the spring allows you to wean peas and bean sowings and harden off tender young plants, while in autumn and winter it will extend your growing season and look after cuttings ready for the new year. It’s also easy to insulate your cold frame for added protection through colder spells.

If you need to stock up on supplies before you get started, we’ve rounded up the essential gardening tools every gardener needs as well as a list of quality Japanese garden tools. Or, if you’re looking for something a little bigger for garden, we’ve put together a guide to buying the best garden shed.

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.
