There have been a lot of posts lately about difficult garden spots, etc. I decided to share what I do. We have a very challenging spot in the yard. On top of a granite outcrop, there are only 1-5 inches of heavy clay soil, nothing that I attempted to grow in the past did well.. So I left it on its own for two years, completely unattended. Conditions changed during this period, from very dry and semi-shade, it became very dry and full sun, because we removed two very large oaks. And besides the regular weeds, here is what did well.
