This looks really good. Do you know how long it has been in training?
I'm not sure, i think about 6 years.
I bougth it from a clubmember.
He took it out of the forrest in the NL,
it was growing under a fallen tree and was
over 3m tall.
Larch closes wounds relatively well if the tree is strong growing. Have you tried enhancing callus forming by scarring the wound edges and then covering the edges with vaseline?
