Chinese Chestnut as bonsai?
« on: May 22, 2013, 11:14 AM »
I've been assisting a doctor at the local university in his chestnut restoration work. I've come across a Chinese chestnut, Castanaea mollissima, about three years old with stunted growth that I think would be suitable beginning material for a nice broom style bonsai.

I haven't found any literature on using chinese chestnut as bonasi. Today, I decided to go ahead and defoliate a single branch to see if a new flush would produce smaller leaves.

Has anyone had any experience with this species as bonsai material?

I too would be interested in responses to this thread, I have a couple 2nd year seedlings of Castanaea (mollissima x pumila) and / or (mollissima x dentata). My seed was a uncontrolled hybrid swarm, so the genetics is mixed, but dominated by C. mollisima.

This is beginning of 3rd growning season, and I repotted at bud swell in April, and severely cut back and shaped roots, got rid of tap roots. Amazing, even trees where I removed more than 2/3 the roots, they leafed out just fine. Leaves are coarse, the trees seem to want to grow very quickly. They are distantly related to oaks, in the absence of advice from people with experience, my guess would be is to treat them like an oak. But I don't know.
