First made popular in Africa, keyhole gardens are catching on in Texas and other hot, dry places. Keyhole gardens hold moisture and nutrients due to an active compost pile placed in the center of a round bed. Although most helpful in hot and dry locations a keyhole garden will improve growing conditions in just about any climate.
From a bird’s eye view the garden is shaped as a keyhole. A notch is cut into a round garden bed, the notch makes for easy access to the center compost well.
The notch allows access to the heart of the garden

I have never heard of this gardening technique before, what a wonderful idea if you have space.
Composting, irrigation and garden, all in one.

Wow … I love this idea! How very clever and efficient! We are hoping to move next year … hopefully I’ll end up with a yard and I’d love to install a keyhole garden. Thanks, AV … what a wonderful surprise!

>Small, sorry, day out, so I’m late getting back. I never thought of you when I posted this because you live in an apartment. So pleased to hear you are moving back to reality and have some space. I hate living in boxes.
