Sooty Mold on Crepe Myrtle Indicates Aphid Infestation

Diagnosis

Black, fire-scorched bark look = sooty mold on aphid honeydew. Aphids suck sap, excrete sugar-rich honeydew.

Treatment

Scout for aphids at leaf-out (sticky, wet leaves).
Systemic insecticide for aphids (ask nursery).
Mold disappears after aphids controlled.

Key Takeaway

Sooty mold is a symptom; aphids are the cause. Systemic treatment clears both.
