I've been asked to cut back a 6 foot potter blank mission tree. It has been allowed to lean on its side over the years and by now the root ball has shifted such that it cannot be righted. It has four shoots which i will leave. Two from this year that are a foot tall, two from last that are around two feet tall. I will propogate all the cuttings I think, I would likely try from fresh! Should I put wax on the cut ends? Should I put wax where I cut the tree? Any suggestions?
