Why does your Pachypodium lamerei 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 while feeding on the sap of the Pachypodium. They often cluster in the crevices between the succulent stem and the leaf bases.
Certain species of scale insects produce white, filamentous filaments that resemble cotton. They attach to the stem of the Madagascar Palm and suck nutrients, which can lead to localized swelling or yellowing.
This fungal pathogen manifests as a white, dusty coating on the surface of leaves. While less common in the arid environments preferred by Pachypodium, it can occur if there is high humidity and poor air circulation.
