5 Signs That It’s Time to Check Your Trees for Fungal Infection

Tree fungal infections can cause serious harm to trees and even lead to their death if not detected and treated promptly. You need to keep an eye out for the signs and symptoms of these infections as early detection and treatment can greatly increase the chances of saving the tree. It is especially important to check for tree fungal infections when the tree is actively producing new growth and during periods of stress. Regular tree maintenance like proper pruning and mulching can help prevent harmful fungi. Here are common signs that alert you to check your trees for fungal infections.

1. Discolored or Wilted Leaves

Discolored or wilted leaves are one of the most common signs of tree fungal infections. Look for changes in leaf color or a decrease in greenness, often accompanied by wilting or curling of the edges. Additionally, yellow, brown, or black spots can be an indication of fungal growth. With some types of fungal infection, the wilted leaves may become covered with a white, powdery substance.

2. Excessive Fruiting Bodies

Excessive fruiting bodies, such as mushrooms or toadstools, can also signify tree fungal infections. While some fruits are beneficial to trees, too many can be a sign of a fungal infection. Likewise, some types of fungi have unique fruiting bodies that are easily identified, like the bright orange and yellow bracket fungi. Remember, not all fruiting bodies are harmful, and it is important to get a professional diagnosis to determine the best course of action.

3. Cankers on the Trunk or Branches

Another sign of tree fungal infection is cankers on the trunk or branches. Cankers are discolored areas that often appear sunken or dead. They may appear as lesions, bulges, or dead patches of bark. The infection can also cause discoloration of the wood beneath the bark, resulting in a discolored spot on the trunk or branch.

4. The Tree Is Actively Producing New Growth

In addition to keeping an eye out for these signs of tree fungal infections, regularly inspect your trees during the growing season. This is when the tree is actively producing new growth and is, therefore, more susceptible to infection. This increased susceptibility can be compounded if the tree has experienced recent stress.

5. Periods of Stress

Lastly, inspect your trees during periods of stress, such as prolonged drought or extreme temperatures. During these times, trees are more likely to be affected by fungal and other infections, so it is important to keep an eye out for any signs of infection.
