Last fall I had a tree service cut down five black locust trees in my yard. The stumps were ground down and all debris removed. This spring I am getting new sprouts all over my yard from the underground roots left over from the trees. Can anyone suggest a way to eliminate these sprouts? I have been pulling them up, but the more I pull, the more grow back in their place! Help!
PS: These sprouts are thorny too! I live in NJ by the shore.
