We are going to remove a 25-year-old honey locust tree in our yard because of the huge amount of seed pods that drop all Fall & Winter. Can we plant another tree near where this tree was and how far away? I was told that whatever the distance of the top of the tree is will be the distance that the roots are spread out. We should not plant another tree within the root area. If that is the case, we would have to plant at least 12 feet away from the tree. Can you advise?
