Insects and Diseases

Mixed results on the impact of Emerald Ash Borer on the Blue Ash. It has been identified that Blue Ash is a host for the borer, however, it may be able to survive an attack. More research is required on this tree species. Based on this, it would be recommended not to plant widely in a urban setting but may be good in a naturalization project.
