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.

What does a diseased oak tree look like?

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.
