Ash tree leaves

Asked August 17, 2017, 2:55 PM EDT

My very large, 25 year old ash tree is losing bright yellow clumps of leaves already. Other ash trees in the neighborhood only have a few yellow clumps. My tree has had to compete for sunlight for years because of the neighbor's 2 large ash trees, so I had many dead branches which I had removed last summer. Is this tree slowly dying? Is there something I should be doing?

We are unable to asses the tree's health without seeing it or sharp photos. The best way to determine whether the tree is dying is to ask a certified arborist or forester to take a look at it onsite and diagnose the problem.

In the meantime, these diagnostic tools may be useful:
