Today, a friend sent a link about Keyhole Gardens, a type of raised-bed garden that protects soil and creates a bigger crop for difficult growing areas. I think this is one of the greatest ideas ever.
They are teaching this type of gardening to the people in Lesotho, but I think it would be a great type of garden to have here in California: easy to maintain, easy to plant, easy to harvest.
I found the above photo on Flickr. You can also see this harvest-ready garden also on Flickr. Or visit the Save a Cow web site. It has more photos and instructions. Or see the AfriGadget web site for more photos and information.
