Troubleshooting
Hikuri problems — and how to fix them
Hikuri (Lophophora diffusa) 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.
Soft, discoloured, rotting body
Overwatering or cool, damp conditions causing rot, the leading cause of death. Use a mineral mix, water minimally, and keep dry in winter.
Etiolated, pale, soft growth
Insufficient light. Provide the brightest direct sun possible to restore compact form and colour.
Shrivelled, sunken crown
Underwatering in summer or natural winter contraction; a deep growing-season soak rehydrates it. Some winter shrinkage is normal and protective.
Mealybug infestation
Cottony mealybugs lodge in the wool and at the roots. Inspect when repotting and treat promptly by removal or an appropriate insecticide.
Prevent hikuri problems before they start
Most hikuri issues are care-mismatch, not bad luck. Dial in the basics:
