dying branches on rowan tree

Question

Over the last 6-8 weeks, two branches of our rowan tree have had the leaves curl and go brown with many dropping off. It has now spread downwards from the top of the tree to where they join the main trunk at about head height. The branches are about 8 cm diameter where they join the trunk. There is some evidence of isolated leaf curl and die back on some other branches. Can you suggest what this might be?

Answer 1

Ash Tress have been plagued with issues the last decade.
I would suggest you have the tree inspected by a qualified Arborist to make a correct diagnosis.
