Care tips
It requires bright, indirect light; direct sunlight can scorch its leaves. Water when the top inch of soil feels dry to the touch, avoiding waterlogging which can lead to rhizome rot. It prefers a well-draining, organic-rich substrate, such as an orchid mix or a peat-based mix with perlite. A common mistake is overwatering and low humidity, which can cause leaf edges to dry out or the plant to lose vigor.
