Mealybugs

These small insects secrete a white, waxy, cotton-like substance to protect themselves. In Frithia pulchra, they often hide in the crevices between the leaf rosette and the base of the plant.

Very Common

How to confirm: Use a toothpick to gently probe the white spots; if they move or are firmly attached to the plant tissue, it is likely an infestation.

Sclerotinia (Soft Rot)

Certain fungal pathogens can manifest as white, fuzzy mycelium on the surface of succulent tissues, especially if moisture is trapped in the rosette. This is often accompanied by tissue softening or mushiness.

Common

How to confirm: Check if the area under the white spots feels soft, slimy, or has a foul odor.

3 Repot the plant in a highly well-draining substrate, such as a mix containing perlite or clay pebbles, to prevent moisture from trapping in the leaves.

warning

Fungal Mold (Saprophytic)

In high humidity environments, common molds like Botrytis can grow on dead organic matter or decaying leaf tips of the Frithia. This usually occurs when airflow is restricted around the rosette.

Common

How to confirm: Inspect if the white spots are strictly on dead/browned leaf edges rather than living green tissue.

1 Remove any decaying leaf tips or dead organic matter from the rosette to eliminate the mold's food source.
