Two-Spotted Spider Mite Infestation

These microscopic arachnids thrive in the warm, dry conditions often favored by Echeveria. They pierce the succulent's cells to suck out sap, leaving behind fine silken webs and causing the dark purple leaves of the Black Prince to look dull or faded.

3 Improve airflow around the rosette and ensure the soil is not staying too damp, as high humidity can encourage mite activity.

warning

High Humidity/Condensation Webbing

While rare, if water is trapped in the rosette of a Black Prince Echeveria during cool nights, it can create a film that mimics fine webbing or promotes fungal hyphae growth. This is usually accompanied by leaf translucency or rot rather than just dry webs.

Common

How to confirm: Check if the 'webbing' feels sticky or damp and if the leaves underneath are softening or turning mushy.

1 Inspect the center of the rosette for any signs of mushy, translucent leaves or dark rot, and carefully remove any dead or decaying material to prevent fungal spread.

2 Improve airflow around the plant and ensure the rosette remains dry by avoiding overhead watering, especially during evening or cool hours.

3 If the plant shows signs of fungal growth, apply an organic fungicide to protect the healthy tissue.
