I am looking for information about Sweet Gum tree diseases. I was told my Sweet Gum tree that is about 30 years old has an aneurysm. It has three holes about two inches deep about 24 inches from the dirt line. What can I do for this tree to save it?

Sweetgum may be attacked by canker diseases. These diseases cause sunken areas on the trunk and some cause profuse "bleeding". Infected bark and sapwood will be brown and dead. There is no chemical control for canker diseases. Severely infected trees will die. Prune cankers out of lightly infected trees. Maintain tree health by watering and fertilizing.
Leaf spots of various types may attack Sweetgum, causing premature defoliation, but are not serious. Rake up and destroy infected leaves to help control if there are no adjacent Sweetgum to add inoculum.
good luck.if this is not helpful call your county exten office in ph book.
