I purchased an Acer Osakazuki from homebase this weekend. Its stems had been tied together, it was placed in the middle of a large group (obviously not optimal conditions) and the pot had dried considerably. This had caused the central leaves where it had been bound to die and some of those stems to blacken. I got a very good price for it and hoped to bring it home and rescue it. I immediately pruned back all the dead foliage, leaving some blackened stems bare in the middle, but with good leaf growth at the top, where the tree was not constricted. Over all it is a very attractive tree and I hope the stems will grow new shoots next year, but wonder if anyone can offer some advice if I can do anything to help it along? Whether I should cut back the blackened stems completely to allow new growth?
