Troubleshooting
Velvet Cotyledon problems — and how to fix them
Velvet Cotyledon (Cotyledon velutina) 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.
Botrytis grey mould in leaf hairs
Trapped moisture in the dense indumentum creates ideal conditions for Botrytis in humid or poorly ventilated spaces. Improve airflow, water only at the base, and remove affected leaves promptly.
Root rot from overwatering
Roots are sensitive to prolonged wet conditions. If the plant wilts but soil is moist, suspect root rot — unpot, trim rotten roots, dust with sulphur, and repot in fresh dry mix.
Scale insects
Brown or tan disc-like bumps on stems and the undersides of leaves. Remove by hand or with a cotton swab dipped in isopropyl alcohol. Neem oil spray helps prevent reinfestation.
