When disease strikes, tree health can decline quickly. Identifying the early signs of disease is crucial to prevent the problem from spreading and to protect your property. At Sawtooth Tree Service, our local arborists can identify diseased trees and then determine whether they can be treated or if they should be safely removed to prevent safety hazards. Here’s a look at five general signs of tree disease. Discolored or Wilting Leaves Healthy trees typically have vibrant, full leaves during the growing season. When a tree becomes diseased, the leaves often turn yellow, brown, or black. You may also notice wilting or drooping leaves, even when the tree has adequate water. These symptoms can indicate fungal infections, bacterial diseases, or other underlying health issues. Unusual Growths on the Bark or Trunk The presence of growths—like cankers, galls, or fungi—on the trunk is a strong indicator of tree disease. Cankers often appear as sunken, dead areas of bark, while galls are abnormal, swollen growths caused by pests or infection. Fungus growing at the base of the tree can suggest decay inside the trunk, which can weaken the tree’s structure. Premature Leaf Drop When trees shed their leaves before the end of the growing season, it’s often a sign that the tree is under stress. While premature leaf drop can occur due to environmental stressors, it is also a common symptom of diseases like anthracnose. Dead or Dying Branches Branches that appear brittle or have no leaves or suggest a potential problem. Disease can cause parts of the tree to die off as it struggles to maintain healthy growth. Dead branches not only indicate disease, but also pose a safety risk since they are prone to breaking and falling. Cracks or Peeling Bark The bark serves as a protective layer for a tree, and when it begins to crack or peel, it’s often a sign of disease. Bark damage can occur due to infections, decay, or pests that compromise the tree’s outer layer. Deep cracks may expose the tree to further infections and reduce its ability to transport water and nutrients, leading to further decline.
