diseases of trees

Diseases of trees are caused by fungi, bacteria, viruses, or pests that infect or harm the tree’s tissues. They can lead to symptoms such as wilting, discoloration, abnormal growth, leaf spots, or dieback. These diseases weaken the tree’s structure, reduce its ability to transport nutrients, and may ultimately cause death if untreated. Factors like weather, poor soil conditions, and wounds can increase susceptibility. Proper diagnosis and management—such as pruning, applying treatments, or improving growing conditions—are essential to protect tree health and longevity.
