African keyhole gardens

"An African “keyhole” is a raised bed system and has been used in Africa for a long time. The idea is to enrich the soil as one grows plants, provide an efficient way to water and conserve moisture, protect the garden from critters, and allow for easy access. Recently, this style of garden has been used in America and modified slightly in sustainable garden use."
