What are the common indications that a tree has a disease?

Orange County Tree Service • 16 January 2024

Healthy trees make beautiful additions to landscapes. But when trees become diseased and their health worsens, they can become more prone to falling over in high winds, creating a major safety hazard. If you think that any trees on your property may be diseased, it’ll be best to have an experienced arborist come out to inspect them and determine whether the tree can be saved, or if it should be removed to eliminate a safety risk. At Orange County Tree Service, our local arborists are experts at identifying diseased trees. Then, we can determine the best course of action. Here are four signs that a tree is diseased.


Fungal Growth

Fungi can wreak havoc on a tree's health, and the presence of fungal growth is a clear sign of trouble. Mushrooms, conks, or slime molds growing on or around a tree can indicate internal decay. Fungi can weaken the structural integrity of the tree and compromise its ability to thrive. If you notice any unusual fungal growth, it's important to consult an arborist to assess the extent of the damage. Early intervention will give the best chance to save the tree from declining health.


Leaf Discoloration

Healthy trees typically exhibit vibrant green foliage, but when a tree is unwell, its leaves may turn yellow, brown, or even black. Discoloration can be attributed to various issues, including nutrient deficiencies, fungal infections, or pest infestations. 


Bark Abnormalities

The bark serves as the protective outer layer of a tree, and any abnormalities in its appearance may signal an underlying issue. Cracks, cankers, or lesions on the bark can be indicative of disease, pest damage, or environmental stress. Careful examination of the bark's texture and color can help identify potential problems early on.


Premature Leaf Drop

A healthy tree follows a seasonal pattern of shedding its leaves, usually in the fall. However, if a tree starts dropping its leaves prematurely, it is a cause for concern. Premature leaf drop can be a sign of stress, disease, or even root problems.
