Reducing height of Sumach
My neighbour has a sumach (Rhus typhina) in his garden but over the last year it's put on at least a foot in width and height and still going. Is there a way of reducing it at all. I've never pruned a sumach and, as the leaves don't seem to appear along the branches (just at the ends) I'm not sure if it will regrow if he cuts it back by about a third. If he cuts out a complete branch it will be out of balance. It's a lovely shape and beautiful colours in the Autumn, just getting a bit unruly.
