Troubleshooting
Pinellia ternata problems — and how to fix them
Pinellia ternata (Pinellia ternata) 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.
Invasive spread
Self-sows and drops leaf bulbils prolifically, colonising beds and lawns. Deadhead spathes and confine to a buried pot or bottomless container to control it.
Summer dormancy mistaken for failure
Foliage naturally yellows and dies back in heat; the tuber is alive. Mark the spot so you don't dig or replant over it.
Leaf scorch in dry sun
Hot, dry, sunny sites brown the foliage and force early dieback. Move to shade and keep soil moist.
Acrid-tuber poisoning risk
Raw tubers are dangerously irritant if chewed by curious pets or children. Site away from play and pet areas and clear stray bulbils.
