Heart-leaved Pinellia problems — and how to fix them
Heart-leaved Pinellia (Pinellia cordata) 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.
Corm rot
Overwatering or poorly draining soil causes the corm to rot at the base. Ensure the pot has drainage holes and allow the top of the compost to partially dry between waterings. Reduce water significantly in autumn.
Leaf scorch
Direct afternoon sun bleaches and scorches the heart-shaped leaves. Move the plant to brighter indirect light or dappled shade. Ensure adequate soil moisture in warmer months.
Failure to re-emerge after dormancy
If the corm is kept too cold and wet over winter it may rot. Store dormant corms in barely moist, frost-free conditions (above 5°C/41°F). Check for firmness before replanting in spring.
