I have an Mt. Hemlock that I collected 20 years ago which has been doing great. However, about a week ago several needle bundles suddenly turned brown. Each needle in the bundle turned brown with no green at all. When I say suddenly I am talking within hours. I can’t for the life of me think of anything I have done that might have caused this. I am scared beyond belief that my tree is dying. I removed the dead needles and washed the foiler mass just to be on the safe side in case something had gotten on them to cause the problem. Then today I found a few more needles.
Any suggestions are appreciated … Desperate Hemlock
