I recently moved into a home in Bloomington MN. The previous owner, I don't know how long ago, up to 40 years ago, put dirt and rocks around an oak tree to form a small hill (See attached picture). We'd like to remove this hill to make it ground level as it once was. Can we dig out the hill without killing the tree?
