Blog How to Spot Signs of Disease in Your Trees Nov 27, 2025

Your trees are not just part of your landscape; they are vital elements that contribute to your property's aesthetic and environmental health. However, maintaining healthy trees requires vigilance, as diseases can silently invade and compromise their well-being. At Gray’s Tree Service Inc., we understand the importance of early detection to prevent minor issues from turning into costly problems. Here's how you can spot signs of disease in your trees and what to do about it.

First, examine the leaves. They are often the most visible indication of your tree's health. Watch for discoloration, such as yellowing, browning, or unusual patterns. Leaf spots can suggest fungal infections, while wilting might indicate insufficient water or root issues. Furthermore, excessive leaf drop during the growing season can also be a sign of trouble. Healthy trees should maintain a consistent canopy density, so any sparse foliage should be noted.

Next, take a closer look at the branches and trunk. Cracks, cankers, or lesions on the bark can indicate disease or pest infestation. Observe if there are areas where the bark is peeling away, which could reveal internal decay. Dead wood is another significant indicator; small branches may naturally die off, but numerous dead branches signal a deeper problem. Also, the presence of mushrooms or fungi growing on the trunk or at the tree base suggests the tree might be rotting internally.

Pay attention to the roots and the base of the tree. Although tree roots are largely underground, the area where the trunk meets the soil can show signs of disease. Look for soft areas, sawdust (a telltale sign of carpenter ants or termites), or lifting soil that might indicate root rot or instability. Ensuring proper drainage can help prevent root-related diseases, as waterlogged roots are more susceptible to pathogens.

Throughout the year, it’s vital to monitor the overall growth of your trees. Stunted growth or a decreased annual growth rate often suggests stress, disease, or poor soil conditions. Keep an eye out for unusual growths, such as witch’s brooms, which are dense growths of twigs caused by disease or infestation.

Another subtle yet significant sign of tree disease can be seen in the tree’s flowers and fruit. Malformations or changes, such as blackened flowers or shriveled fruit, can indicate specific diseases. Trees that fail to flower or produce fruit according to their usual schedule may also be experiencing health issues.

Once you've identified potential signs of disease, it's crucial to act promptly. At Gray’s Tree Service Inc., we recommend regular professional evaluations to accurately diagnose and treat tree diseases.
