Keyhole Gardens: Growing Food in Arid Regions

Keyhole gardens are the stars of a new grass roots agrarian movement that allows gardeners to grow food successfully by creating a raised garden with the no-dig, layering concept of a lasagna garden and recycled materials instead of soil. The pictured garden has a center compost basket that distributes nutrients and water to the surrounding garden bed and is accessible by a keyhole notch opening in the circular design.
