Tracing is when you incise around a wound to cut back to undamaged bark, and bevel its edges down to the juicy cambium layer. From those juices will grow the callus that is a tree's scar tissue for healing its wounds. Basic to the repair of all tree wounds is remembering that a tree's sap circulation is longitudinal, not lateral, throughout all its members. To help any wound heal you must shape it at both ends into points, like the ends of an ellipse. This lets the cambium channels merge again after having been separated by the wound's width. Within these rejoining points callus will form evenly, without interruption, about a half inch each growing season. |
