Question From: CALIFORNIA
Q: the top half of our mountain ash tree is bare and the branches are a darker reddish brown while the bottom half is a lighter brown and sprouting new leaves. did the top half die over winter and should I cut it back that far?
I recommend you get an onsite inspection from a certified arborist. I am not trained in blind pruning. To find a professional in your area go to tcia.org and enter your zipcode. Nancy and Happy Yardening.
