Learn how to build a garden hot bed with industrial strength to extend the gardening season from eight months to a year or more.

EDITORS NOTE: Animal manures contain E. coli and other bacteria that can cause illness. This article suggests using a base layer of fresh manure in the hotbed to generate heat. This is okay for germinating seedlings like tomatoes. However, it isn’t safe to use fresh, uncomposted manure near plants you’ll eat directly for food (like leafy greens), and using these plants in a hot bed should be avoided. Learn more about home composting.

Here are plans for an industrial-strength hotbed that you can use eight months a year or more in most climate zones. It features nearly 18 square feet of protected planting area and a foundation built of lightweight concrete partition blocks that are worthy of a house.

This hotbed is rugged enough to last many years while withstanding the worst weather that nature can muster. Too good to be true? Hardly. The best part is that it’s easy to build, and you can do it in a weekend.
