Why does your Acer tegmentosum have sticky leaves? Diagnose the cause and fix it with our step-by-step guide.
Pet FriendlyAphids are small, soft-bodied insects that pierce the leaf tissue of Acer tegmentosum to suck out sap, excreting a sugary substance known as honeydew. This honeydew creates the characteristic sticky residue on the leaf surfaces and stems.
Scale insects attach themselves to the twigs and leaf petioles of the Manchurian Maple, feeding on phloem sap. Like aphids, they excrete honeydew which coats the surrounding foliage in a sticky film.
While not the primary cause of stickiness, sooty mold is a black fungus that grows specifically on the honeydew left by sap-sucking insects. The presence of dark, velvety patches on the leaves often accompanies the sticky sensation.
Treehoppers feed on the sap of Acer species and are prolific producers of honeydew. Their presence can lead to significant sticky buildup on the canopy of a Tiger Bark Maple.
