Tee, I think that may be the issue. We built this raised bed 3 years ago, all pristine with compost and topsoil mix, but it is completely surrounded by big trees, and I have found that this year, every time I try to plant something in there, I have to cut through tons of roots. I think next spring we are going to have to dig a lot of it out and get rid of some of the tree roots. I don't want to disturb the things that are doing well, though. That is going to take some work. So what grows well in full shade with tons of roots to fight through?
