Oak wilt is a dangerous and deadly fungus that blocks the flow of water inside of trees, causing leaf browning, premature leaf drop, and tree decline. Anthracnose is a scary-sounding yet fairly harmless leaf disease that causes blotchy brown spots on leaves and makes leaves crinkle or curl up.
Why are the leaves on my oak tree curling?
- If the damage began in the hottest part of the summer, it may be drought stress. If the leaves began to curl or drop after a wet spring, it could be anthracnose. Look at the area around the tree. Damage from nearby salt spray can cause leaf edges to appear scorched.

Why are the leaves on my oak tree curling up?
Could this cause this? A: The late spring frost could have started the problem that later spread with a disease of Oak Anthracnose (Gnomonia species), which causes the leaf curl. This disease is found on fallen leaves during the winter. Then the heavy rain that followed the frost splashed the spores onto young leaves.
What does a diseased oak tree look like?
Conks are initially white or light-colored and turn black and crusty with age. Infected trees show symptoms of general tree decline including branch dieback, loss of leaves and yellowing or browning of leaves in summer. Trees weakened by drought stress, wounding or other injuries are most susceptible.
How can you tell if your oak tree is dying?

Watering Problems and Drought Stress Leaves may turn yellow and then brown before falling off the tree. This can occur both during summer heat and extended periods of dry winter cold. Davey Tree advises that drought stress can also cause leaf browning in oak species.
How do you treat a bacterial leaf scorch?
Bacterial leaf scorch has no known cure. A variety of management practices can successfully extend the longevity of infected trees. These include treatment with antibiotics and water stress reduction through mulching, irrigation, and growth regulation.
How do I get rid of oak wilt?
We recommend a trunk injection of Propizol. Propiconazole is a systemic fungicide that will suppress Bretiziella fagacearum. Because Oak Wilt is spread through root grafts and insect carriers, We recommend the treatment of non-infected oaks in close proximity to the infected trees to slow the spread of the disease.
Can a dead oak tree come back to life?
Identifying whether a tree is dead or living can sometimes be a very tricky task – especially in the winter time when every tree can look dead. While it is possible, yet sometimes difficult, to revive some sick or dying trees it is impossible to bring a dead tree back to life.

Can a tree with oak wilt be saved?
Once an oak tree is infected with the oak wilt fungus, the tree will die and there is no treatment to save the tree. When an oak wilt infection is confirmed treatment can be applied to the surrounding trees to prevent the spread of this disease.
What is wrong with my oak tree?
The oak wilt fungus invades the water-conducting tubes of oak trees, eventually causing leaves to wilt and die. All oaks are susceptible to the disease, but oaks in the red oak group, such a red, pin and shingle oaks are more susceptible than oaks in the white oak group, such as white, bur and swamp oaks.
