Why does your Kalanchoe Passion Artemis have sticky leaves? Diagnose the cause and fix it with our step-by-step guide.
Aphids are small, soft-bodied insects that pierce the succulent leaves of Kalanchoe to suck out sap. As they feed, they excrete a sugary, sticky substance known as honeydew.
Scale insects attach themselves to the stems or leaves of Kalanchoe and feed on plant fluids. Similar to aphids, they produce honeydew which creates a sticky residue on the leaf surface.
Mealybugs are sap-sucking pests that appear as small, white, cottony clusters. Their feeding process results in the production of honeydew that coats the leaves.
While not the primary cause of stickiness, sooty mold is a black fungus that grows specifically on the honeydew left behind by pests. It can coat the 'Passion Artemis' leaves, making them appear dark and grimy.
