Why does your Kalanchoe Rosalina Don Alano have white cottony spots? Diagnose the cause and fix it with our step-by-step guide.
These small, soft-bodied insects secrete a white, waxy, cottony substance to protect themselves. They congregate in the crevices of the Kalanchoe leaves and stems, sucking sap and causing leaf yellowing or deformation.
Similar to mealybugs, scale insects can appear as fuzzy or waxy patches on the succulent stems of Kalanchoe. They feed on plant fluids, which can lead to stunted growth and a sticky residue known as honeydew.
While typically presenting as gray fuzz, early stages of Botrytis in high-humidity environments can appear as pale, cottony patches on decaying floral or leaf tissue. This fungus thrives in the stagnant air often found around dense Kalanchoe foliage.
