The Composting 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.
