What is Ash Dieback?

Ash dieback is a serious disease of ash trees caused by the fungus Hymenoscyphus fraxineus (It used to be called Chalara fraxinea). The disease causes leaf loss and crown dieback in affected trees and can lead to the death of the tree.

Ash dieback will begin to kill ash trees within a few years–unless you treat and preserve your trees. We can advise on whether you want to treat your ash trees as soon as Ash Dieback is found in your area. If your ash tree is in poor health or small, it may be best to remove it.
