Huernia thuretii problems — and how to fix them
Huernia thuretii (Huernia thuretii) 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, darkened stems at soil level from overwatering or cold, wet conditions. Cut back to firm tissue, callus, and re-root in dry gritty mix; water more sparingly.
Etiolation
Thin, pale, stretched stems and reduced flowering in low light. Move to a brighter window with some direct morning sun.
Mealybugs
White cottony clusters in stem grooves and on roots. Treat with isopropyl alcohol and check the root ball for root mealybugs.
Shrivelling
Puckered, soft stems indicate under-watering or, if the soil is wet, root loss from rot. Match the fix to the soil's moisture state.
