overgrown griselinia

Peggy O\’Connor asked 13 years ago

I have a griselinia hedge lined avenue which is 30 odd years old it has formed an arch which I would like to maintain. the only problem is it seems to be dying on me. I have tried to cut out as much dead wood as I can. It has new shoots but these quickly loose their leaves and become bare and also brown or black at the tips. What could I do it would be a shame to loose this beautiful feature. Is pruning an option because these are now more trees than shrubs. thanks

This sounds like the tree, or more than one tree in the hedge, is suffering from honey fungus root disease. Pruning does not help … all you can do is wait and see if it progresses, which is likely.
