Healthy trees enhance the beauty and value of your property. However, diseases can threaten their health, making trees more likely to topple over or drop large branches in high winds, creating serious safety hazards. Identifying the signs of a tree disease early can help you take action to restore the tree or decide if removal is necessary. At JSK Tree Care, we can identify diseased trees. Then, as needed, we can safely remove them. Here are five warning signs that a tree has a disease.

Discolored or Wilting Leaves

A common sign of tree disease is discoloration or wilting in the leaves. Fungal infections, like anthracnose, often cause leaves to turn brown or yellow prematurely and may lead to wilting. Wilting can also result from vascular diseases that limit water flow, such as Verticillium wilt. If your tree’s leaves look unhealthy out of season, this could be a sign of disease that needs immediate attention.

Unusual Growths on Bark or Branches

Fungus-based diseases often cause unusual growths on a tree’s bark or branches. Cankers—sunken, discolored areas on the bark—indicate fungal or bacterial infections that may spread and weaken the tree. Also, fungi growing on the trunk or roots often suggest decay and rot within the tree, which can compromise its structural integrity.

Excessive Leaf Drop

Deciduous trees typically lose leaves in fall, but disease can cause leaves to drop prematurely or in excessive amounts. If you notice significant leaf loss during the growing season, it may indicate a disease. Rapid defoliation weakens a tree by reducing its ability to produce energy through photosynthesis.

Cracks or Peeling Bark

Cracks or peeling bark can signify that a tree is under stress, often due to disease. As infections take hold, they can cause the bark to weaken, dry out, and peel away. Bark splitting can also be a response to a fungal infection or an insect infestation that spreads disease. 

Stunted Growth or Dead Branches

Diseased trees often struggle to absorb nutrients and water, causing growth to slow or stop altogether. Dead branches, especially in the crown, may signal a decline in the tree’s overall health due to disease or pest infestations.
