Acer cappadocicum Sticky Leaves - Causes & Fixes

Aphid Infestation

Aphids are sap-sucking insects that congregate on the tender new growth of Acer cappadocicum. They excrete a sugar-rich substance known as honeydew, which creates the sticky residue on leaf surfaces.

Very Common

Scale Insects

Scale insects attach themselves to the twigs and leaves of the maple tree to feed on sap. Similar to aphids, they produce honeydew as a byproduct of digestion, leading to sticky foliage and potential sooty mold growth.

Very Common

Sooty Mold (Secondary Infection)

While not the primary cause of stickiness, sooty mold is a black fungus that grows on the honeydew left by insects. It covers the leaves of the Cappadocian Maple in a dark, velvety layer, which can impede photosynthesis.

Common
