Trees add beauty, shade, and value to your property, but like any living organism, they are susceptible to disease. Recognizing the signs early can help save a tree, or at least prevent the disease from spreading to others. At The Tree Guy, our local arborists are experts at identifying and addressing diseased trees. Here are four common signs that a tree may be suffering from a disease. Discolored or Wilted Leaves One of the most noticeable signs of a tree disease is when the leaves start to discolor, wilt, or fall prematurely. Healthy leaves should be vibrant and robust throughout the growing season. If you notice yellowing, browning, or blotchy patches on leaves, it could be a sign of various diseases, including anthracnose. Cankers on the Trunk or Branches Cankers are areas of dead tissue on a tree’s trunk or branches and can indicate the presence of a fungal or bacterial infection. They often appear as sunken, darkened, or cracked sections of bark. Over time, cankers can expand, weakening the tree's structure and making it more vulnerable to further damage from pests, weather, or decay. If the cankers are extensive, the tree may be beyond saving and require removal. Fungal Growth on the Tree The presence of mushrooms or other fungal growth around the base of the tree or on the bark is a red flag that there’s internal decay. Certain fungi feed on decaying wood, indicating that parts of the tree are dead or dying. Fungal infections can weaken the tree's structural integrity, putting it at risk of falling, especially during storms or high winds. Dead or Dying Branches Healthy trees typically have full, lush canopies. If you notice dead or dying branches, especially in the upper parts of the tree, it may signal that the tree is battling a disease. Dead branches, also called "dieback," are often the result of root diseases, such as root rot, or stem diseases, like verticillium wilt. These dead branches can be a hazard, as they can fall unexpectedly, potentially causing injury or property damage.
