There are so many diseases out there that your trees can suffer from that a good arborist can really help you in determining what is ailing your trees. Hardwood or deciduous trees can be harmed or killed by disease-causing organisms called pathogens. The most common tree diseases are caused by fungi. Fungi lack chlorophyll and derive nourishment by feeding on (parasitizing) trees.

Many fungi are microscopic but some are visible in the form of mushrooms or conks, while other tree diseases are caused by bacteria and viruses. Some of these include Powdery Mildew Tree Disease; Sooty Mold Tree Disease; Verticillium Wilt Tree Disease; Canker Tree Disease; Leaf Spot Tree Disease; Heart Rot Tree Disease; and Root and Butt Rot Tree Disease, just to name a few.
