Silver Crown Cotyledon problems — and how to fix them
Silver Crown Cotyledon (Cotyledon orbiculata var. oblonga) 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.
Root rot from overwatering
The most common fatal problem. Wilting despite moist soil, mushy stems at the base, and leaf drop all indicate rot. Remove from wet soil, trim rotted roots, allow to dry for several days, and repot in fresh, dry, gritty mix.
Mealybugs
White waxy clusters appear in leaf axils and under leaves. Treat with 70% isopropyl alcohol on a cotton swab, working carefully to preserve the farina. Repeat every 7–10 days for several weeks.
Farina damage
Water splash, handling, or misting leaves permanent finger marks on the white-coated leaves. Always water at soil level and handle plants from the base or pot.
