Crape Myrtle Sticky Yellow Leaves: Honeydew from Insects + Drought Stress

Sticky leaves = honeydew from sap-feeding insects (aphids, scale, whiteflies) on this tree or one above it. Sooty mold may follow.

Steps

  1. Check leaf undersides and nearby trees for insects.
  2. Control insects (see honeydew publication: Honeydew & Sooty Mold).
  3. Yellow leaves + leaf drop = drought stress. Water deeply.
