Why does your Kalanchoe Passion Dione have sticky leaves? Diagnose the cause and fix it with our step-by-step guide.
Aphids are sap-sucking insects that excrete a sugary substance known as honeydew, which creates the sticky residue on Kalanchoe leaves. They often cluster on the undersides of leaves or near new growth.
Scale insects attach themselves to the succulent stems and leaves of Kalanchoe, feeding on sap and secreting honeydew. Unlike aphids, they appear as small, immobile bumps or shells.
Mealybugs are soft-bodied insects that produce honeydew and are often accompanied by a white, cottony wax. They thrive in the crevices of Kalanchoe leaf bases.
Whiteflies are small flying insects that congregate on the undersides of Kalanchoe foliage and excrete honeydew as they feed.
