I have a 10 year old Japanese Maple that has no life on the branches. I have not transplanted it, or changed watering habits or done anything different. No signs of pest infestation. The only new growth is up the entire trunk where there is lots of new leaf growth. What should I do? Prune the entire tree back to any green wood? Or just cut it back to the trunk? Any advise would be appreciated. TIA Merlene Niteowl@netdex.com
