Beech hedging, white powdery stuff?
Hello everyone, we have quite a tall established beech hedge in a house we moved into a year ago - however, a few of the beeches seem to be dying off /dead. I have noticed that there is something white and powdery on the bark, and I wonder if this could be the problem? Photo attached of a tree that's still fairly healthy, but does have this white stuff.
Would appreciate any advice.
