Why does your Kalanchoe Rosalina Don Nando have white cottony spots? Diagnose the cause and fix it with our step-by-step guide.
These sap-sucking insects produce a white, waxy, cottony secretion to protect themselves as they feed on the succulent stems and leaves of Kalanchoe. They often congregate in the crevices between leaf nodes or near the base of the plant.
This fungal disease manifests as a white, flour-like coating on the leaf surfaces. While more common in humid environments, it can affect Kalanchoe if airflow is poor or if moisture lingers on the foliage.
In conditions of high humidity and low ventilation, Botrytis can create fuzzy, greyish-white patches on decaying plant tissue. This often starts at the base of the rosette or where leaves meet the stem.
