I've almost filled up my raised bed. It's a sort of three permaculture ideas in one system. It's a wooden sided version of a horsehoe bed which I've heard so much about via Toby Hemenway's "Gaia's Garden" (got to stop reading that awesome book!). It is layered in lasagne style with cardboard at the bottom, the horse manure in the middle and finally topsoil at the top, with an inch finally of
compost planned from the local composting centre.
Here's a link to the story.
