Help stop the spread of Fire Blight; treat your infected trees
Fire blight is a destructive bacterium affecting fruit trees and other species. It is first identifiable by small cankers in the spring that ooze a light tan liquid, the ooze leaves behind streaks on the branches and trunks turning dark when exposed to air. The infection can more easily be identified later in the year when the tree’s fruit and leaves shrivel, blacken, and die. This infection is highly contagious and lies dormant during the winter, but returns the following spring, infecting more trees.
To control Fire Blight, diseased wood needs to be removed following particular protocols. Some chemical control is effective as well. Both should be done under the direction of a certified arborist. The LCMA has recently contracted with Preservation Tree Care to address Fire Blight issues with LCMA owned and maintained trees.
