Aphid Infestation

Aphids are small, soft-bodied insects that pierce the succulent leaves of Kalanchoe to suck sap, excreting a sugary substance called honeydew. This residue creates the characteristic sticky film on the leaf surfaces.

Very Common

Very Common

These pests produce honeydew as they feed on the plant's sap. They are often accompanied by white, cottony masses in the crevices of the Rosalin Don Juan's fleshy leaves.

Common

Sooty Mold

While not a direct cause of stickiness, sooty mold is a black fungus that grows specifically on the honeydew left behind by sap-sucking insects. The stickiness is actually the food source for this mold.

Common
