We are having trouble with large boxwoods. It is fast moving as the damage wasn't there 4-5 weeks ago. I'm afraid of the answer!! I tried to send off samples for pathology but everyone is telling me a few weeks for results and I'm afraid that may be too late. There are currently 4 boxwoods affected but there are many more on the property.
I've noticed some blackening on the stems that worries me.
Any suggestions??
Thanks in advance!!
I have more photos if needed
