Why does your Othonna clavifolia 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. In Othonna clavifolia, they often cluster in the crevices between the succulent leaves or at the base of the stems.
Certain species of scale insects produce thick, white filaments that resemble cotton. They feed on the sap of the succulent leaves, which can lead to yellowing or shriveling of the finger-like structures.
While typically more fuzzy and gray, early stages of fungal rot in high humidity can appear as light-colored patches. This is common in Othonna if there is poor airflow around the dense succulent leaves.
