Why does your Haworthia cooperi truncata 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 substance that looks like cotton to protect themselves. They feed on the sap of the Haworthia, often clustering in the crevices between the leaf bases and near the roots.
Scale insects can produce a white, fluffy coating that resembles cotton. They attach themselves to the succulent leaves and drain nutrients, which can lead to the eventual collapse of the translucent windows.
In conditions of high humidity and poor airflow, certain fungal pathogens can manifest as white, fuzzy mycelium on the plant tissue. This is particularly common if the succulent's 'windows' have sustained physical damage.
