Snowball Pincushion problems — and how to fix them
Snowball Pincushion (Mammillaria candida) 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.
Basal rot / soft brown base
The leading cause of death, from overwatering or poor drainage. Keep the mix gritty, water only when fully dry, and never let the body sit in damp soil, especially in winter.
Etiolation (elongated, pale body)
Insufficient light stretches the normally squat globe and thins the white spines. Move to the sunniest window; stretched growth cannot revert.
No flowers
Skipping a cold, dry winter rest is the usual reason. Provide cool (around 8-12°C), nearly dry dormancy to set the spring flower ring.
Mealybugs in the spine crevices
White cottony pests hide among the dense spines and at the base. Inspect regularly and treat with diluted isopropyl alcohol on a cotton swab or a suitable systemic.

Most snowball pincushion issues are care-mismatch, not bad luck. Dial in the basics:
