Aphid Infestation

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

Very Common

Scale Insects

Scale insects attach themselves to the stems and leaf bases of Kalanchoe, feeding on plant fluids and producing honeydew as a byproduct. Because they are stationary and look like small bumps, they are often overlooked until the stickiness becomes apparent.

Very Common

How to confirm: Look for small, raised, brownish or tan bumps firmly attached to the stems or leaf petioles.

Sooty Mold Growth

While not a direct cause of stickiness, sooty mold is a fungus that grows on the honeydew left behind by pests. This presents as a black, powdery coating that can make the leaves appear dirty and reduce photosynthesis.

Common
