I have an evergreen tree in my yard that has started to turn brown on several of the branches. I am hoping someone can identify the tree for me. I am attaching a picture of the tree and also a close up picture of a branch. The tree was in our garden when we purchased our home, but I would guess that it is quite old. If anyone has advice on why the tree is turning brown and what we could do about it, I would appreciate the information. Thanks!
