We probably don’t need to mention that growing conditions in Africa are less than ideal; The African Keyhole Garden brings all of the revolutionary ideas necessitated by the limitations of that climate to your garden - enabling you to achieve a higher yield with less work. Keyhole Gardening is a sustainable method - Add alternating layers of brown and green matter (newspapers, cardboard, vegetable scraps, etc.) to the center compost bed. This adds carbon, nitrogen, and air to the soil enabling you to produce a large amount of nutritious, organic food using the least amount of space and the least amount of water. Not only is the African Keyhole Garden drought tolerant, but it is also raised, reducing the need for bending and stooping. Could this be any better? - Yes! The African Keyhole idea is an old idea, but we manufacture it with premium, modern materials, so that all you need to do is give it a quick spray with a garden hose to keep your African keyhole garden looking beautiful year after year - and we’ll guarantee it for twenty years. The African Keyhole Garden is 6’x6’. With a height of 30 1/8”.
