Some more details for us ignorant,
@bonhe ?
It is obvious that the branch changes direction after the bend but....
Thanks for asking Alexandra.
BT has 2 purposes:
1- To create the sudden, sharp turn on the branch like you mentioned.
2- To conserve the energy production for the tree and that particular branch in the mean time to create a new shoot where I want to have. If I prune the branch back to where I want the new shoot, I will get it anyway, but I will sacrify the energy production for that branch. When that branch is still able to produce energy, the new shoot is easy to come out!
The above tree was brought out yesterday to get heavy training (I will post its process later). After almost 3 weeks from the time I used BT on it, most of affected branches (over 20 branches) are alive except one, which is not a big deal for me!
The yellow arrow shows the broken branch. The red arrow points to the new shoot.
The pink arrow points to the breaking area. It heals very well.
The red arrow points to the breaking area.
The branch was pruned back.
