Trees/red oak tree
Expert: Jim Hyland - 7/10/2011
Question
I have two recently planted red oak trees (April 2011) in my front yard. There is sap oozing from cracks in the trunk and some of the branches. This sap is attracting wasps and hornets. Is this harmful to the tree and what (if anything) should I do?
Answer
It sounds like a condition called slim flux.
Slime flux is the name given to the oozing or flowing liquid that is often seen during the heat of the summer on the trunk, large limbs, or basal roots of oak, elm, maple, apple, yellow- poplar, birch, hemlock, and willow. It is usually more common on large, older trees than younger ones.
