My griselinia hedge has suffered in the recent bad frosts and the leaves are all brown. What should I do, should I cut it back?
I have some old and very large apple trees, 15 to 20 metres in height. Is it possible to prune these down to a manageable height? It would probably mean cutting large branches and even the upper trunk back to bare timber, with no growth point. Would shoots grow from cuts like this? And what about the fact that I would be removing over half of the crown? Shold I do it over a couple of years?
