Why does your Kalanchoe Passion Acheron 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 characteristic sticky residue on Kalanchoe foliage. They often congregate on the undersides of leaves and tender new growth.
Scale insects attach themselves to the stems and leaves of Kalanchoe and secrete honeydew as they feed on plant fluids. This residue can accumulate on the leaf surfaces, making them feel tacky.
Mealybugs produce honeydew and are often accompanied by white, cottony masses in the crevices of the Kalanchoe leaves. Their feeding process results in a sticky coating on the surrounding plant tissue.
While not the primary cause of stickiness, sooty mold is a black fungus that grows specifically on the honeydew left behind by sap-sucking insects. The presence of black, velvety patches confirms an underlying insect problem.
