Hard to tell what type it is from the photo. It looks like a hemlock, can you confirm or get a closer image?This tree has been healthy for years .This Spring , a section never turned green . Nothing unusual happened to the tree during the winter months . The branches are definitely dead . What caused this , and is there a treatment ?
IF there were dead branches on the tree (? Yew) before last winter , it had to have been a much smaller area , because I never noticed it . Now , as you can see , the area is quite large . The tree (? Yew) alongside it seems unaffected ; but I’ll look more closely tonight when I take better pictures . No invasive vine as far as I know . I have a lawn service that cuts the grass weekly and trims the bushes/trees yearly in the Fall . I would hope that they would have advised me last Fall if they noticed something wrong - BUT , they haven’t said anything yet ; so now I just don’t know how long the condition has been present . I do feel strongly that if an invasive vine was present , I would have noticed it . Thanks , PT .X2 on the Yew. Taxus densiformus. Doesn't look like a brand new problem to me. Was there some kind of invasive vine on it for a while like honeysuckle or trumpet vine or wild grape?
Thank you Neill for your timely response and advice . … PTIt does appear to be a couple of large yews like mentioned above.besides the large dead spots they appear to be in fair condition to me. Check out this article:
