Evergreen tree turning yellow #568694
Asked June 09, 2019, 1:25 PM EDT
We have a tree that looks like a large yew (although I don't know for sure). It is turning yellow in places throughout. First the needles turn light green and then to yellow. The bark is peeling on the tree but I think that is normal? I have lived here 2 years and haven't seen the tree do this. Usually when it loses a twig or branch the needles are more of a rusty brown color.

Mineral deficiency is a common cause of yellowing. Insects or a fungus can also be the cause. Observing when and where the yellowing occurs will be useful in deciding which of the causes is affecting your tree.

I just want to confirm that you think (from the photos) that what I have is in fact a yew?
The needles look right and although the bark is a little fuzzy in the picture it appears brown and flaky. I5 also appears to be about 20ft. Tall. So I think it is a yew.
