Nephthytis is an easy plant to care for and grow as long as it is placed in a bright light situation. It will tolerate lower light levels, but be aware that it will become thin, weak and leggy in low light. Direct, hot sunlight can scorch the leaves of the plant or fade the variegation, so a north-facing window is best.
Water the plant until the soil is damp. Wait until the top of the soil is dry before watering it again. The plant begins to droop when water is needed but will perk up when hydrated. Over-watering will lead to root rot, which can kill the Nephthytis.
