Troubleshooting
Golden Barrel Cactus problems — and how to fix them
Golden Barrel Cactus (Ferocactus glaucescens) 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
The most common problem, caused by overwatering or poorly draining soil. Signs include a soft, discoloured base. Allow the medium to dry completely between waterings and ensure a free-draining mix.
Etiolation (stretching)
Pale, elongated new growth indicates insufficient light. Move to a brighter location with direct sun for several hours daily.
Corking
A natural browning of the lower body as the plant ages; this is normal and not a disease. Distinguish it from rot by the firm, cork-like texture.
Scale insects
Small brown or white bumps on the body. Remove with a cotton swab dipped in isopropyl alcohol or treat with neem oil solution.
Sunscorch
Pale yellow or white scarring on the sun-facing side when moved abruptly from low light to intense direct sun. Acclimatise gradually over 2-3 weeks.
