Why does your Monanthes polyphylla have white cottony spots? Diagnose the cause and fix it with our step-by-step guide.
These small insects produce a white, waxy, cotton-like secretion to protect themselves. They feed on the sap of Monanthes polyphylla, often congregating in the tight rosettes or near the base of the leaves.
In high humidity, fungal pathogens can create white, fuzzy mycelium on decaying leaf tissue. This often occurs when the dense rosette of Monanthes polyphylla traps moisture between leaves.
This fungal disease manifests as a white, flour-like coating on the leaf surfaces. While less common in succulents than in foliage plants, it can occur if airflow is restricted around the rosette.
