Troubleshooting
Bearded Huernia problems — and how to fix them
Bearded Huernia (Huernia barbata) 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.
Stem and root rot
The most common and serious issue, caused by overwatering or cool, wet conditions. Stems turn soft and transparent at the base. Remove all affected tissue with a clean blade, dust with sulphur, dry out thoroughly, and re-root any healthy cuttings in dry gritty compost.
Red or purple stem discolouration
A stress response to excessive direct sun or heat. While not immediately fatal, it indicates the plant should be moved to a slightly shadier spot. Healthy stems are green; red stems are under stress.
Mealybugs
Mealybugs settle in stem crevices and at the root zone. Treat by dabbing with isopropyl alcohol on a cotton swab or applying a dilute neem oil solution; check at every watering as infestations spread rapidly in warm conditions.
