In the post on azalea shopping there is an example of bridge grafting to close a wound (https://bonsaitonight.com/2017/05/19/some-notes-on-shopping-for-azalea-bonsai/)
Does anyone have any more information or experience with this technique? I have not seen it described in any detail anywhere. I am assuming it is like an approach graft but on both sides of a large chop in order to increase the flow and thus the healing process. How does it get oriented? Does it eventually get removed? Any more details would be greatly appreciated.
