        Preventing a Split or Break
          David identified the two most important points
        of the branch to protect. One point was where the
        separated live end merged with the trunk. The other
        point was a major stress point on the branch where
        the heaviest bend would occur. Failure to secure these
        points would almost guarantee a split at the wrong
        section or break along the branch.
          To prevent this, David further secured the merg-
        ing point of the live end and the trunk with grafting
        tape. Once the grafting tape was set, he used raffia to
        thoroughly wrap the base of the separated live end.
        He repeated the process through the entire branch
        overlapping as he worked upwards to the apex of the
        branch. Additional layers of raffia were made around
        the segment of the branch where the heaviest bend
        would be made. Once David had reached the point
        where the bend would no longer occur, the raffia was
        tied and knotted to prevent unraveling.
