Mealybugs

These small, white, waxy insects cluster in the crevices of the Echeveria leaves and at the base of the rosette. They feed on plant sap, which can weaken the plant and cause leaf drop over time.

Very Common

3 Gently wipe away the white coating with a soft cloth and ensure the plant is in a well-ventilated area with bright, indirect light.

warning

Natural Farina (Epicuticular Wax)

Echeveria pulvinata is known for its heavy coating of farina, which can sometimes look like white patches or fuzz. This is a protective layer and is not a disease.

Common

How to confirm: Observe if the white texture is uniform across parts of the leaf and if it feels smooth or slightly powdery rather than clumpy.

1 Inspect the white spots closely; if they are part of the leaf surface and cannot be wiped off easily, they are likely natural farina.

2 Avoid touching or wiping the leaves, as removing this protective wax can make the plant vulnerable to sunburn and pests.

3 Check for actual pests like mealybugs by looking for moving insects or sticky residue; if found, treat with an organic insecticide.
