What is Oak Wilt?
Oak Wilt is caused by a fungus that invades the vascular system of oak trees, restricting water flow and eventually killing the tree. Red oaks are especially vulnerable, often dying within weeks of infection. White oaks are more resistant but can still be affected.
How Does Oak Wilt Spread?
The fungus is primarily spread in two ways:
- Insects: Beetles that are attracted to fresh wounds on oak trees can carry spores from infected trees.
- Root Grafts: The fungus can also spread through underground root systems, especially in closely planted trees.
Symptoms of Oak Wilt
Look out for the following signs of Oak Wilt:
- Rapid leaf discoloration: Leaves turn brown or bronze, especially starting at the top of the tree.
- Leaf drop: Leaves may fall off even in spring or summer.
- Wilting branches: The canopy may appear wilted or thinning.
If you notice any of these symptoms, contact Tree Wise Men LLC right away. Early detection is key to managing Oak Wilt and preventing its spread.
Preventing Oak Wilt
Here are a few ways to help protect your oak trees:
- Avoid pruning oaks in spring and summer: This is when beetles are most active and can spread the disease.
- Seal wounds: If you need to prune or if the tree is damaged, apply wound paint immediately to prevent infection.
- Professional care: Have a certified arborist inspect your trees regularly for signs of Oak Wilt and other plant health issues.
