Phytophthora Bleeding Canker

Phytophthora Bleeding Canker affects many tree species found in Massachusetts. Beech, Birch, Maple, Oak, Willow, Cherry, Dogwood, Apple and many others are among the varieties that can be damaged by this fungus that blocks the transport of water within the infected tree. The affected area can be easily spotted by discolored bark and weeping (or bleeding) ‘sores’ from which brown or red liquid may ooze. Cracked and missing bark will lead to decay, structural issues, and eventual death of the tree.

Bug Busters will treat your valuable tree by assessing the tree’s growing conditions – such as soil moisture level and drainage. Soil testing may also be required.
