Troubleshooting
Elegant Ball Cactus problems — and how to fix them
Elegant Ball Cactus (Parodia concinna) 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
More susceptible than desert cacti if kept wet in cool conditions. Ensure the substrate dries partially between waterings and the pot drains freely.
Crown rot
Water sitting in the slightly sunken crown can cause rot. Always water the soil rather than the plant itself.
Mealybugs
Cottony masses between ribs or at the soil line. Treat with isopropyl alcohol on a cotton swab; check for root mealybugs if above-ground infestation persists.
Sunscald
Bleached, papery patches on the top after sudden intense sun exposure. Acclimatise gradually when moving to brighter positions.
Failure to flower
One of the most reliable bloomers in the genus — if no flowers appear, suspect insufficient light or lack of a cool winter rest (10-15°C).
