Common Problems of Ash Trees
(Posted on 3/1/2011)
Ash trees are no longer recommended
for planting in the Midwest because of the threat
of the emerald ash borer, a highly-destructive
wood-boring insect pest. However, ash trees remain
important as up to 6 percent of woodland trees and up
to 70 percent of urban trees are ash species. Other ash problems are often mistaken for emerald ash borer infestation, so ash trees may be needlessly removed or treated with pesticides as a result. This diagnostic guide is intended to help you distinguish
emerald ash borer injury from other common problems of ash.
