Why does your Pereskia spathulata 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, cotton-like substance to protect themselves as they feed on the sap of the Pereskia leaves and stems. They are highly common in leafy cacti and can quickly spread through clusters of stems.
Similar to mealybugs, scale insects produce a white, felt-like coating over their bodies. On Pereskia spathulata, these may appear as stationary, fuzzy bumps on the undersides of leaves or along the succulent stems.
This fungal pathogen manifests as a fine, white powdery coating on the surface of the leaves. In high-humidity environments, this fungus can thrive on the broad, non-succulent leaves characteristic of this species.
While usually associated with gray fuzzy growth, early stages of Botrytis in humid conditions can appear as pale, fuzzy patches on decaying leaf tissue. This is particularly common if the Pereskia has poor air circulation.
