Hello Peter, I bought a home last year and found several fruit trees on the property. One of the trees is a donut peach tree I am told. Unforetunatly there was a very large chinese chestnut tree that crowded it out and forced it to lean one way. I would like to save it, however it looks very sad and I am not sure when or what to do to help it straighten out. I should mention that it is a full grow tree as well. Do you have any suggestions?
