MethodTray / container with water
The pot stands in a container of water. While the roots are weak — a layer of 1-2 cm, do not submerge it halfway. Change the water completely, do not just top it up

Acceptable, but not needed in semi-aquatic mode — water is supplied from below

Risks & warnings
- The tuber may rot from cold + overwatering in the awakening phase (no leaves = little evaporation)
- All parts are toxic if ingested (calcium oxalates) — keep away from children/animals
- Grows fast and gets big — needs pot volume and nutrition
Care notes
- •Bulb cutting is a tuber fragment, not a finished plant: plant it in warm, damp substrate and wait for a sprout (2-6 weeks)
- •Growing point (eye) up, cover with 2-3 cm; warmth of 22-26°C speeds up awakening
- •Do not repot until the roots are strong — ideally until they show from the drainage holes
- •Summer outdoors: pot in a container of water, container in the shade. It needs warmth, not sun — the task of the phase is to build up roots
- •Bring indoors before nights below 15°C (end of October); before bringing in, quarantine for 2 weeks — inspect leaf axils and the undersides of leaves
- •Heavy feeder and big drinker — keep the soil moist, feed per canister B
- •The dark coloration is brighter in bright light; full sun only for a mature plant with a developed root system, not for a tuber with a couple of leaves
- •Not as sensitive to salts as alocasia — RO is not required, but helpful
- •In winter it may go dormant (drop its leaves) — the tuber is alive, keep it warm and slightly moist
