The Hemlock Wooly Adelgid

The hemlock wooly adelgid, a small aphid-like insect from Japan that has become a serious pest of the eastern hemlock, has been detected in hemlock trees in several Colonial Acres properties. If you have hemlock trees on your property that you wish to save from this serious threat, it's important to their health that you inspect them regularly for the adelgid and undertake a program of control on affected trees. Infested trees typically begin to look badly and then to die in a relatively short time - 3-4 years; trees that do not die of the infestation can become weak and susceptible to storm damage.

For recommendations of tree services that will deal effectively with an infestation, email the Cornell Cooperative Extension at mastergardeners@ccealbany.com or call them at 518-765-3514.
