Why does your Kalanchoe Passion Amora have sticky leaves? Diagnose the cause and fix it with our step-by-step guide.
Aphids are common pests for Kalanchoe species; they pierce the plant tissue to suck sap, excreting a sugary substance known as honeydew that creates the sticky residue.
Scale insects attach themselves to the stems or leaf undersides of Kalanchoe; like aphids, they excrete honeydew as they feed on the plant's vascular fluids.
These pests produce a sticky residue and are often accompanied by white, cottony masses in the crevices of the Kalanchoe leaves or at the leaf bases.
While not the primary cause, sooty mold is a black fungus that grows specifically on the sticky honeydew left behind by sap-sucking insects.
