Since 2006, a tip blight on eastern hemlocks has been observed across a wide area in central and southern Maine. The tip blight apparently affects only the tips of branches, seldom killing more than 0.5-inch of shoot tip growth. Often, however, tens or hundreds of shoot tips are affected on a single tree.
