Wound patch grafting ?

[Paulneill]

I recently read about a technique were an extra flap of cambium/ bark is kept and folded over to close a wound when removing branches. I am very Intrested in trying this method on some of my trees in the future.
After some research I discovered it is not only possible to fold the cambium from the original tree onto the wound but to cut a patch of cambium/bark and literally patch a wound and get It to graft completely covering the wound. I believe this is called patch budding and mostly used by nusery men on fruit trees to attach a different variety of tree.
I even saw a picture of a patch at least 3 by 3 inches on a mature tree.

Does anyone have any info on the subject or tried any of the 2 tecniques mentioned ?

Hi Paul,
We use patch budding to graft some thick barked species like walnuts - mainly because you can't lift the thick bark for a T bud graft.
I believe the patch bud relies on the cambuim layer on the wood where you have removed the bark uniting with the cambium on the piece of bark you use for the patch. I think this means that it will only work where there is intact cambium under the patch??? If you have done carving or removed a branch, etc the cambuim will be gone so I don't think the patch would take properly.

It would still be worth trying though. Maybe if you can get cambium contact around the edges it might be able to join up there and the new cambium may be able to grow faster under the protection of the new bark patch....
