Years ago, we had mounds of Black-Eyed Susans in the backyard. These mounds were located on the outside of three aptos blue pine trees. It was one of many transformations the backyard went through over a period of thirteen years. Eventually, the mounds were removed and lawn was planted. Naturally, since the mounds were watered well for the flowers, the tree roots thrived making the mounds more difficult to remove. There are a lot of birds and insects still not talking to us because of the mound removal.
