Q.Hedge seems to be dying
Hi.i noticed part of my hedge dying a few weeks ago. The hedge is about 12 or 13 yrs old. I had assumed it had gotten damaged by the snow we had in March but now it appears to be travelling and the 2nd hedging has dead leaves on it. Could this be caused by some sort of disease and can it be sprayed with something to prevent the whole hedge from dying? Thanks, linda
I can't make a diagnosis from just these images but the fact that it is spreading would suggest a fungal issue.
Clean up any dropped leaves and dispose of.
Treat with a fungicide.
