In referring to "older material" above I should have distinguished this better as "developed material in bonsai containers." In the ground trees will grow much more vigorously, and ginkgoes can live to be ancient (there are some that are hundreds of years old around temples in Japan) so returning the oldest gingko you could possibly find (50 years?) you could expect it to behave the same way, with rapid growth if you were to hypothetically put it in the ground.

The danger would be in expecting a ginkgo to heal well in the confines of a bonsai pot, or even a nursery container. I have some that were developed from ground layers and clumps that are 35 years old, and they are showing little sign of healing over. One even has an axe wound in the trunk from where it was separated from the mother tree. It's been in containers all its life and the wounds are all still there.

So free growth = callus tissue and wound healing. It won't happen overnight and it is extremely unlikely that a ginkgo wound larger than a dime or so is going to heal well if the tree is in a bonsai pot and not growing rapidly.

Regards,

Matt
