What's underneath is at least 2 feet of the same stuff, it never changes. Ask me how I know It's all organic dirt and decomposed granite, the entire valley I live in is. I've got several geology books that concur with me, there's no clay or anything else where I live.

How can I add clay to it? Can it be purchased in dried powdered form and mixed in with my dirt?
