Of course, it is always possible to work with the
        higher branches on a tree as well. However, most bon-
        sai artists want to create strength in their tree. Trees
        that have thick trunks with foliage too high tend to
        look unbalanced and weak. Bringing a heavy branch
        down requires a special technique that can help give
        the tree a stronger appearance.

        Timing Considerations
          Seasonal timing is extremely important when de-
        ciding to perform a heavy brand bend, especially for
        California Junipers. David performs his heavy bends
        during the cold season. This season can range from
        November to April depending on the climate. Since
        bending a heavy branch puts a lot of stress on the tree,
        it will need time to recover. Cooler weather will lessen
        the shock that the tree has sustained and permit it to
        heal. Hot weather can put too much stress on the tree,
        especially the bent branch.

        The Tools
          Prior to beginning the technique, David went over
        his tools. It was interesting to see how many tools were
        required for the technique. Bending a heavy branch
        definitely required much more than just standard
        bonsai tools. He utilized many power tools including
        a reciprocating saw, a jigsaw, drill, and die grinder.
        Multiple sizes of wire were spread across the table as
        well. Once all the tools were laid out and ready to go,
        it was time to start.

        Protecting the Live End
          The first thing that David mentioned was that bend-
        ing a heavy branch required adequate preparation of
        the branch. When working with a California Juniper,
        it was essential to protect the live end or live vein of the
        tree. Since the live end provides the nutrients gained
        from the roots to sustain the branch, damaging or sev-
        ering the live end would risk losing the entire branch
        and possibly the entire tree. To distinguish the live
        end from the dead wood, David peeled the bark away
        from the trunk to expose the reddish cambium. He
        continued to peel all the bark away from the branch to
        fully expose the live end. Once the live end was easily
        visible, it would be much easier to discern where the
        cut could be made.
