This southerly view shows clearly the section I excised from the wrap-around root. There are new roots growing toward the east and toward the south. I will nurture that small root heading south. It may eventually turn into a major root for this tree.

You can't really see this very well, but the cut root closest to the camera has built up a callus where it is in contact with the brick. This helps to firm up the tree's anchorage. Unfortunately, there are no new roots growing from this cut root.
