While, there is currently no remedy for this problem in our forests at large, there are several treatment options for those hemlock trees, large and small, in our landscapes. This means that in the future the only hemlocks around will be those that are being conscientiously maintained with an effective, consistent treatment strategy.

The HWA first came to the United States from Asia in the 1920's. This introduced pest has worked it’s way up and down the East Coast. Adelgid cause hemlock trees to weaken, and eventually die. The tree first takes on a paler shade of green, then needles begin dropping. In cases of heavy infestation, complete defoliation can occur in as little as twelve months. If your trees are infested you’ll probably notice the white, cottony masses that contain up to 300 eggs per puffball. It’s no wonder the pest can spread over a tree so fast!

Most of the devastation, so far, has been up north, but the pest is now in our area, and we are seeing unprecedented infestation rates here that foretell a rapid decline of our local hemlocks. There are large stands of hemlocks trees in Shenandoah National Park which have been completely wiped out! It is imperative that we begin treating any trees we want to save immediately.

Appalachian Tree Care is leading the way in the Blue Ridge Mountains in hemlock woolly adelgid control.
