Why does your Haworthia limifolia have white cottony spots? Diagnose the cause and fix it with our step-by-step guide.
Mealybugs are small, sap-sucking insects that secrete a white, waxy, cotton-like substance to protect themselves. On Haworthia limifolia, they often cluster in the crevices between the fleshy leaves where moisture accumulates.
Similar to mealybugs, these scale insects produce white filaments that look like cotton. They attach to the base of the Haworthia leaves and can cause the plant to become stunted or lose its characteristic ruffles.
In conditions of high humidity and poor airflow, certain fungi can manifest as white, fuzzy patches on the leaf surface. This is often a sign that the Haworthia's environment is too damp for its succulent nature.
