Troubleshooting
Thorny Adenia problems — and how to fix them
Thorny Adenia (Adenia globosa) 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.
Root rot during winter dormancy
Even a single watering during leafless dormancy at cool temperatures commonly leads to fatal rot beginning at the caudex base. If soft spots develop, excise all affected tissue with a sterile knife, dust with sulphur or charcoal powder, allow to callus for 1–2 weeks in a warm, dry spot before replanting.
Spine and caudex surface damage from handling
The long, stiff spines can cause injury and the sap causes skin irritation. Always handle with thick leather gloves. Repot infrequently and disturb the root system as little as possible — Adenia globosa resents root disturbance.
Failure to produce leaves in spring
If the plant remains leafless into late spring with no bud swell, it may be too cool (below 18 °C) or the caudex may be exhausted from a previous rot episode. Move to a warm, bright location (above 22 °C) and apply a small amount of water to the soil surface to trigger growth.

Most thorny adenia issues are care-mismatch, not bad luck. Dial in the basics:
