Typhonium brownii problems — and how to fix them
Typhonium brownii (Typhonium brownii) 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 in dormancy
Overwatering the resting tuber is the commonest killer. Once leaves yellow, keep the medium nearly dry until new growth appears.
Leaf-edge browning
Low humidity or dry air scorches the thin blades. Raise humidity with grouping or a tray and keep out of heating-vent draughts.
Failure to emerge
Tubers held too cold or too wet over winter may rot or stay dormant. Store dormant tubers warm and barely moist.
Sudden dieback mistaken for death
Natural seasonal dormancy looks like failure; the tuber is alive underground. Don't discard the pot — resume watering when shoots return.
