Troubleshooting
Silver Crown problems — and how to fix them
Silver Crown (Cotyledon undulata) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Farina damage and leaf marking
Water droplets, handling, or misting permanently damage the white powdery coating, leaving dark fingerprint-like marks. Always water at soil level and avoid touching the leaves unnecessarily.
Root rot from overwatering
Cotyledon undulata is highly susceptible to root rot if soil stays moist, particularly in cool or low-light conditions. Use gritty, fast-draining mix and allow thorough drying between waterings. Brown, mushy stem base indicates rot — remove and re-root healthy cuttings.
Mealy bugs
Soft white insects cluster at leaf bases or on roots. Treat with 70% isopropyl alcohol on a cotton swab at the first sign; a systemic insecticide drench can address root mealy bugs. Inspect regularly when repotting.
