How do YOU keep your perennial bed healthy under a tree?
I have had a bed for several years under a tree and am planning to replant it. Before I do, yes, I am planning to do a soil test, etc. and get everything squared away, but I have had trouble in the past with the bradford pear that the previous owner's planted there (and my DH loves) sucking the life out of the soil so that plants aren't happy. I want to do this right, so I would love to know what most people do under a tree in their yards to keep everyone happy that is planted there. What is your yearly method for introducing needed nutrients back into the soil under a tree or am I the only one that has trouble with life-sucking trees?
