Why is my oak tree dripping black sap?
Answer: It sounds like your oak trees have slime flux or “wet wood,” which is a bacterial growth in your tree. This bacteria causes a buildup of carbon dioxide and pressure within the tree. This pressure buildup forces sap out of the tree, which is the yeasty smelling liquid which you see leaking out of the trunk.
What is the black stuff that falls from trees?
