Drippy oak or Drippy Acorns Disease

If you observe a brown sap-like fluid dripping from Live Oak acorns, leaves or twigs, you might be seeing Drippy oak or Drippy acorns (Erwinia quercina) disease. Not thought to be detrimental to the health of the tree, the dripping may cause a bit of a mess if affected branches overhang a driveway, seating, or play area. Dripping takes place when small insects inflict wounds on the Live Oak tree. A bacterial reaction takes place and the brown liquid is produced. Usually, the dripping does not last past a few weeks.
