Light

Tolerates low to bright indirect light but grows best in medium to bright, filtered light. Variegated varieties need more light to maintain coloration. Avoid direct sun which can fade colors.

Water

Water when top 1–2 inches of soil dry out. Keep soil moderately moist during growing season. Reduce watering in winter. Use room-temperature water. Overwatering causes root rot.
