Troubleshooting
Rodent Tuber problems — and how to fix them
Rodent Tuber (Typhonium flagelliforme) 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 poor drainage
Although this species prefers moist conditions, sitting in waterlogged soil causes rapid tuber rot. Ensure the growing mix is moisture-retentive but free-draining. Use containers with adequate drainage holes and never let pots sit in standing water for prolonged periods.
Leaf tip browning
Brown leaf tips indicate low humidity or dry air. Raise humidity with a pebble tray or humidifier, and keep away from heating vents or air conditioning units. Ensure soil moisture is consistent and the plant is not experiencing drought stress.
Propagation difficulty by conventional means
This species rarely sets viable seed in cultivation outside its native range, and tuber offset production can be slow. Division of tubers when replanting is the most practical approach. Tissue culture is used commercially for mass propagation but is not practical at home.
