Troubleshooting
Piaranthus punctatus problems — and how to fix them
Piaranthus punctatus (Piaranthus punctatus) 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.
Overwatering rot
Soft stems blacken and collapse from soggy soil, especially in cool months. Water only when fully dry, never in winter, and use a gritty open mix.
Mealybugs
White cottony clusters hide among the stems and on the roots. Spot-treat with alcohol or apply a systemic insecticide and inspect the root ball when repotting.
Failure to flower
Usually from too little light or no cool, dry winter rest. Provide brighter summer light and a dormant period to trigger the spotted blooms.
Sunscorch
Bleached or scorched patches on stems from abrupt exposure to strong direct sun. Acclimatise gradually and filter fierce midday light.
