Troubleshooting
Indian Head Notocactus problems — and how to fix them
Indian Head Notocactus (Notocactus ottonis) 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
Caused by overwatering, especially in winter. The plant is particularly susceptible when temperatures are low; keep it almost completely dry from autumn to early spring.
No flowers
Requires a cool, dry winter rest and ample direct sunlight during summer to flower reliably. Ensure at least 4 hours of direct sun daily during the growing season.
Mealybugs at root
Root mealybugs are hard to detect until the plant wilts. Unpot, inspect the roots, wash off pests, and repot into fresh dry compost.
Etiolation
Elongated, pale new growth indicates insufficient light. Move to a sunnier window.
Scale insects
Brown bumps on the stem body. Remove manually and treat with neem oil dilution.
