Huernia pillansii problems — and how to fix them
Huernia pillansii (Huernia pillansii) 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.
Rot (high susceptibility)
The soft bristly stems rot easily if kept damp. Water only when bone-dry, use a very gritty mix, and ventilate well; behead and re-root above any rot.
Fungal blemishes
Black or brown spotting on the tubercles in humid, still air. Improve airflow, reduce watering, and remove affected stems promptly.
Etiolation
Stems stretch and lose their dense bristly character in low light. Move to a brighter spot with gentle direct sun.
Mealybugs
White pests hide among the bristles and tubercles where they are hard to spot. Inspect closely and treat with dilute alcohol on a cotton swab.
