Keyhole gardens are basically raised beds with an access path and built in compost column. After I published Keyhole Gardens are a Proven Strategy for Working With Caliche in Arid Regions, I got a ping back from Mr. Jon Moore at World Organic News.
I revisited his site in response to his ping and found a nice collection of articles on key hole gardens. At first, I was going to reblog them as I read them. Then I saw how many wonderful articles he collected and decided I needed a new strategy. So, I strongly recommend that you visit Mr. Jon Moore at World Organic News. and search his site for key hole gardens. Mr. Jon Moore is proving to be a wonderful addition to my Desert Gardening Community.
