Why does your Ficus aurea have sticky leaves? Diagnose the cause and fix it with our step-by-step guide.
Scale insects attach themselves to the stems and undersides of Ficus aurea leaves, sucking sap and excreting a sugary substance known as honeydew. This residue creates the characteristic sticky film on the leaf surface.
Aphids are soft-bodied insects that congregate on new growth and leaf buds of the Golden Fig, feeding on phloem sap. Their excretion of honeydew causes leaves to become tacky and often leads to secondary sooty mold growth.
Mealybugs are related to scale and produce honeydew as they feed on the plant's vascular system. They are often accompanied by a white, cottony substance near the leaf axils of the Ficus.
While not the primary cause of stickiness, sooty mold is a black fungus that grows directly on the honeydew left by sap-sucking insects. It can coat the Ficus leaves in a dark, crusty layer, reducing photosynthesis.
