The wooden cold frame is also ideal for over-wintering your plants, protecting them from the winter weather. The Cold Frame can be placed on paving or pea shingle where the stored heat generated by the stone will help with hardening off; you may want to place the frame directly over crops in open soil or, thanks to our clever design, the cold frame can be easily secured to one of our 1.2m (4ft) square Allotment or Standard Raised Beds for instant protection from the seed sowing stage onwards.
If you have grown some tasty crops you can be sure that if not protected the slugs and snails will get to them first, apply copper slug and snail tape around the top of the cold frame to stop them from coming in, if you have any small gaps around the cold frame base sit your plants on a layer of slug gone this irritates the slugs/snails foot and they will look for food elsewhere.
