Why does your Hibiscus rosa sinensis Cheerleader Clear Pink have sticky leaves? Diagnose the cause and fix it with our step-by-step guide.
Aphids are sap-sucking insects that target the tender new growth of 'Cheerleader' Hibiscus. They excrete a sugary substance called honeydew, which creates the sticky film on leaf surfaces.
Scale insects attach themselves to stems and leaf petioles of Hibiscus, slowly feeding on phloem sap. Their waste product also results in a sticky honeydew coating that can attract sooty mold.
Whiteflies congregate on the undersides of Hibiscus foliage and suck plant juices. The resulting honeydew can coat entire leaves, making them feel tacky to the touch.
While not the primary cause of stickiness, sooty mold is a black fungus that grows specifically on the honeydew left by pests. It can make the leaves appear dirty and matte under the sticky residue.
