I have a couple of apple trees I think might need something. I've only mulched around it, and keeping that up is getting annoying. Is comfrey even the best plant?
If so... where would I find it? If not, what should go under my trees instead?
Common comfrey spreads. Bocking 4 and 14, which are the ones you most often see for sale, don't spread. The seeds are sterile so they get bigger around and you can propagate them easily by taking a cutting of a
root and planting it somewhere else. I personally wouldn't plant common comfrey because it's too hard to contain, but I have hundreds of bocking 4 comfrey plants. Comfrey is certainly one of the best plants if it grows well in your area. I have sent plants to people nearly everywhere and the only people that seem to have any issues with it growing are in very hot, dry climates. I don't know if that would apply to you or not.
