I tried for half an hour to post this over on the plant forum, but it wouldn't let me. So I'm putting it here, sorry. Has anyone really studied Sepp Holzer's plant family chart and planted things according to it, and gotten results, good or bad? It is a weird chart, at least as far as my visual sense is, and I'm not sure I understand the tree-like structure of it. And have you noticed a comparison between his plant families and the regular companion planting that is more commonly used?
