I have an ash tree (>20 years old, ~30' tall) that seems to have died. It began losing leaves starting from the lower branches to the top early last summer and had very few leaves come out on the top branches this spring. It was treated twice for emerald ash borer (EAB) and multiple people have seen no evidence of the EAB. I am trying to understand what killed this tree. Any helpful ideas?
Hennepin County Minnesota
Can you tell me more about what the tree was treated with and when? Did a certified Arborist recommend treatment? Did the tree show other symptoms or signs of stress before the treatments? Perhaps a change in it's surroundings, construction, moisture, critter holes, root girdling, etc.?
