Title: Cupressaceae dying in Suffolk Co.NY
Answered by: Barbara Medford
QUESTION:
I have noticed that all of my Cupressaceae (& others I see in my area) are dying. They turn yellow, then rust & brown til they are everbrowns. what is going on?ANSWER:
We answered an almost identical question from Sufflock Co., NY last year, and will suggest you read it and see if you get some help. In a nutshell, we believed the problem to be mites, which were a big problem virtually all over the country last year and are apparently coming back.
