Troubleshooting
Huernia hystrix problems — and how to fix them
Huernia hystrix (Huernia hystrix) 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 stem rot
Soft, blackened, collapsing stems at soil level from overwatering or cold-wet conditions. Cut well above the rot, let cuttings callus, and replant in dry gritty mix.
Etiolation
Stems stretch thin and pale and flowering stops in low light. Move to a brighter spot with some direct morning sun.
Mealybugs
White cottony tufts hide in stem grooves and at the base. Dab with isopropyl alcohol and check the roots, where root mealybugs also lurk.
Shrivelled, puckered stems
Under-watering during the growing season, or rot has killed the roots. If the soil is dry, water; if wet, unpot and inspect for root loss.
