Aphid Infestation

Very Common

Sooty Mold Secondary Infection

While not the primary cause of stickiness, sooty mold is a black fungus that grows directly on the honeydew left by sucking insects. This can make the leaves appear coated in dark, sticky soot.

Very Common

How to confirm: Check if a black, powdery substance is growing specifically on top of the sticky patches on the leaves.

Scale Insects
