Why does your Kalanchoe Rosalina Don Bombero have sticky leaves? Diagnose the cause and fix it with our step-by-step guide.
Aphids are common pests for Kalanchoe species that suck sap from the undersides of leaves, excreting a sugary substance known as honeydew. This residue creates the characteristic sticky texture on the leaf surfaces.
Scale insects attach themselves to the stems and leaf petioles of Kalanchoe, feeding on plant fluids and producing honeydew as a byproduct. Unlike aphids, these pests often look like small, stationary bumps or shells.
Mealybugs secrete honeydew while feeding on the succulent tissues of the plant. They are often accompanied by a white, cottony substance in the leaf axils.
In certain environmental stresses or physical damage, Kalanchoe may exude sap directly from broken leaf tissues. While less common than pest-related honeydew, it can result in a tacky surface.
