Care tips
It prefers bright, indirect light; direct sunlight can scorch its delicate leaves. Keep the soil consistently moist but avoid waterlogging, allowing the top layer to dry out slightly between waterings. Use a well-draining, organic-rich potting mix. A common mistake is insufficient ambient humidity, which can lead to brown leaf tips; consider using a humidifier or misting its leaves regularly.
