Year-Round Gardening: Our Best Plans for Greenhouses, Hoop Houses, Cold Frames and More

Easy Cold FrameShorter days and tumbling temperatures needn’t put a halt to your supply of homegrown food. When the growing gets tough courtesy of Jack Frost and company, take action by outfitting your garden with a homemade selection of season-stretching gear. The icing on the cake? Many of the devices you make can also get things growing sooner come spring!

Here, you’ll find our best ideas and plans for DIY cold frames, greenhouses, hoop houses, low tunnels, cloches and other tools that can keep the harvests coming throughout fall and beyond. The dozens of projects range from elaborate and permanent to quick and simple, and many can be made from recycled materials. Have some juice or milk jugs? Turn them into fast cloches. How about some used windows? Fashion an easy cold frame (see photo, right).

No matter the size or style of your plot, you’ll find an effective garden-protection strategy that fits your budget.
