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 Plan
David stressed the importance of planning prior to even considering a bend. Bending a branch for the sake of only bending does not accomplish much. There must always be a purpose for performing the bend. After studying the tree and choosing a front, David illustrated his plan for how the bend would improve the overall style of the tree. With that plan, David would then be able to control the bend into that location and adjust accordingly as needed.
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.
