Signs that a Tree Is Diseased & You Should Call the Local Arborist

Trees promote environmental health, while also adding beauty to our surroundings. However, just like any living organism, trees can fall prey to diseases that can harm or kill them. Identifying the signs of a tree disease early is crucial for giving infected trees the best chance of survival. At Mauricio’s Tree Service, our local arborists are experts at identifying diseased trees. Then, we can determine whether the tree can be saved or should be safely cut down. Here are five warning signs that a tree has a disease.
Leaf Discoloration
One of the most common signs of a tree disease is a change in the color of the leaves. Healthy leaves should have a vibrant and consistent color. If you notice unusual yellowing, browning, or blotches on the leaves, it may indicate a problem. For instance, sudden oak death can cause brown or black leaf spots in oak trees, while chlorosis results in yellowing leaves due to nutrient deficiencies.
Premature Leaf Drop
If your tree starts shedding its leaves well before the fall season, it's a sign that something might be wrong. While leaf drop is a natural process, excessive or premature leaf loss is a cause for concern. Trees with diseases such as Dutch elm disease or oak wilt may exhibit this symptom, as they can obstruct the flow of water and nutrients, leading to leaf wilting and dropping.
Fungal Growth
Fungi can be a major contributor to tree diseases, and their presence on a tree can be a telltale sign of trouble. Look for unusual fungal growths on the trunk or branches, as well as mushroom-like structures or cankers. Fungal diseases like anthracnose, root rot, and powdery mildew are just a few examples that can manifest as visible fungal growth.
Reduced Growth and Dieback
Stunted growth is a sign that a tree may be struggling with a disease. You might notice that the branches or twigs are not producing new growth as they should. In severe cases, there may be dieback, where entire branches or sections of the tree are no longer producing leaves or growing.
Pest Infestations
While pests themselves are not diseases, they can weaken trees and make them more susceptible to diseases. Look for an increased presence of pests, such as aphids, scale insects, or borers, as they can create wounds and provide an entry point for pathogens.
