Blog Spotting Tree Diseases Early: Signs to Watch Out For Nov 11, 2025

Caring for your trees is vital for maintaining a healthy and beautiful landscape. Trees offer shade, improve air quality, and add aesthetic value to your property, but they can also become susceptible to diseases if not properly cared for. Spotting tree diseases early is crucial as it helps in managing the issues before they escalate into more severe problems. In this guide, we'll explore the signs to watch out for, helping you keep your trees healthy with the expert assistance of Gray’s Tree Service Inc.

Early detection of tree diseases often starts with a keen eye for abnormal changes. One of the first signs to observe is discoloration in the leaves. Leaves turning yellow or brown prematurely can indicate a root issue or a disease affecting the foliage. For instance, if your oak trees develop yellowing leaves during spring or early summer, it might be a symptom of oak wilt, a serious fungal disease that can spread rapidly if not controlled.

Inspect your trees for signs of wilting or drooping leaves, as this could suggest water stress or the presence of vascular diseases like verticillium wilt. This disease blocks water flow, causing wilting and leaf drop. If left untreated, verticillium wilt can eventually kill the tree.

Another telltale sign of tree diseases is the presence of cankers. These are sunken, dead areas on the tree's branches or trunk. Cankers are often caused by fungi and bacteria, making them a significant concern. Look for discolored patches or sunken lesions, which could indicate a canker disease. Swift action is essential to prevent the disease from spreading to the entire tree.

Pay attention to unusual growths or damage on the bark. For example, bark may become loose or peeling, which is often a symptom of fungal infections like cytospora canker or anthracnose. These conditions commonly affect hardwoods such as sycamores and maples and can be detrimental if not addressed.

Pest activities, like increased insect presence, can also be a precursor to disease. Beetles, in particular, can introduce pathogens into trees, resulting in diseases such as Dutch elm disease or emerald ash borer infestations. Regularly check for boreholes, sawdust-like frass, or other signs of insect damage on your trees.

Additionally, monitoring the base of your trees for mushroom growth is crucial. Mushrooms growing around the base could mark the presence of Armillaria root rot, a condition that affects the roots and can compromise the structural integrity of the tree.

Managing these conditions requires vigilance and timely intervention. Partnering with a professional tree service, like Gray’s Tree Service Inc, can significantly benefit homeowners in early detection and management of tree diseases. Experts can provide tailored care, such as pruning affected areas, applying appropriate treatments, and even preventative care to keep your trees in peak health.
