Troubleshooting
Orange River Climbing Onion problems — and how to fix them
Orange River Climbing Onion (Bowiea gariepensis) 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.
Bulb dehydration during prolonged dormancy
If kept too dry for too long in very hot, sunny conditions, the bulb may gradually shrivel. A single light watering in mid-dormancy (if the bulb looks visibly shrunken) can stabilise it; resume full watering only as autumn temperatures drop.
Fungal spotting on bulb surface
Brown or black spotting on the green bulb surface in high humidity conditions indicates fungal infection. Reduce ambient humidity, improve air flow, and apply a dilute copper fungicide; ensure the bulb neck does not sit in damp soil.
Slow growth or no vine emergence
A very small pot or depleted soil can limit vine production. Repot in fresh gritty mix in a slightly larger container at the start of the growing season. A brief cool, dry rest stimulates emergence more reliably than continuous warmth.
