How to Build a Keyhole Garden
I’m a big fan of raised bed gardening approaches: I really don’t want to do a ton of digging, and, as an urban homeowner, I need to maximize the space I have. So I was intrigued when I ran across this post on the keyhole garden, a raised-bed style of gardening that originated in Africa.
The plan below provided by a reader at The Homesteading Boards is intriguing (though also expensive, as he mentions). Make sure to click through to appropedia’s page on the keyhole garden, and watch the videos available: you may get some ideas for simpler and less expensive approaches. If you do, of course, let us know about it.
