Why does your Kalanchoe Passion Aris 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 sap, excreting a sugary substance known as honeydew. This sticky residue often attracts ants and can lead to the growth of black sooty mold on the foliage.
Scale insects attach themselves to the stems and leaves of Kalanchoe, feeding on plant fluids and producing sticky honeydew as a byproduct. Unlike aphids, they appear as stationary, bumpy, shell-like growths.
Mealybugs are sap-sucking pests that produce honeydew and are easily identified by their white, cottony, waxy coatings. They often hide in the tight crevices where the succulent leaves meet the stem.
Some Kalanchoe species possess nectar-secreting glands as part of their natural biology to attract beneficial insects. This is a physiological process rather than a pest issue, though it can mimic the appearance of honeydew.
