Title: Chinkapin oak (Quercus muehlenbergeii) weeping sap
Answered by: Nan Hampton

QUESTION:

Help, help! Our Chinkapin Oak is weeping sap along the trunk. There is no sign of damage. What can we do?

ANSWER:

Mr. Smarty Plants had a question of a similar nature several months ago and I consulted with Eric Beckers of the Texas Forest Service for his expert advice.  This is what he said:

"This sounds like wetwood, also known as slime flux, a bacterial disease that enters through a wound.  The pressure caused by the bacteria growing inside the tree usually produces a foaming weep that is very attractive to insects.  A healthy oak should be able to close the wound and shut down the bacterial ooze.  In the meantime, a periodic hosing down of the weep will cut down on insect activity and the pungent aroma."

It doesn't sound like a serious problem, but keep your eye on your Quercus muehlenbergii (Chinkapin oak).  If it begins to show obvious signs of stress, it might be a good time to call in a professional arborist.  Here is more information on wet wood or slime flux from the Univeristy of Illinois.

Thanks for stopping by to visit Mr. Smarty Plants at the Wildflower Center Plant Sale last week.
