Levy's Huernia problems — and how to fix them
Levy's Huernia (Huernia levyi) 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 from overwatering
The most common problem, particularly in winter or cool, damp conditions. Stems soften and collapse at the base. Remove all rotted tissue immediately with a clean blade, treat with sulphur, and re-root healthy stem sections in dry gritty compost.
Stem stress colouration
Reddish or purplish discolouration of stems indicates excessive direct sun exposure or heat stress. Relocate to a spot with bright but filtered light. The plant will recover normal green colouring once the stressor is removed.
Root mealybugs
Huernia levyi can harbour root mealybugs that are invisible without removing the plant from its pot. Signs include slow growth and unexplained wilting. Unpot, rinse roots, treat with insecticide, and re-pot in fresh, dry compost.
