Hi Paul. I do have a question. Sepp talks about the symbiotic relationship between his plants on his farm, and how incredibly healthy they are because of it. But he also mentions he has plants growing next to each other, in fact helping each other, that others say can't grow where they are growing.
So the question is, how did he figure out what plants work well other plants? Was it all trial and error? Are there resources the rest of us can turn to? Thanks.
