Lesser Theriophonum problems — and how to fix them
Lesser Theriophonum (Theriophonum minutum) 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.
Tuber rot from improper dormancy
If watered through the dry dormant season, the tuber rots rapidly. Cease all watering as leaves die back and resume only when new growth breaks in early summer.
Cold damage
This tropical species has no frost tolerance. Bring indoors or protect from temperatures below 18°C. Even brief cold snaps can kill the emerging growth or damage the tuber.
Failure to re-emerge after dormancy
If the tuber was too wet, too cold, or too stressed during dormancy it may fail to regenerate. Check tubers are firm and healthy before the monsoon season begins; discard any that are soft or shrunken.

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