Care Requirements
LightBright, indirect light; tolerates medium light. Avoid harsh direct sun, which can fade and scorch leaves.
WateringWater sparingly and only when the top 1–2 inches of mix are dry. Bottom-water or use small, frequent sips to avoid root rot.
SoilA very airy, fast-draining mix: 40% fine bark or coco chips, 40% peat/coir, 20% perlite/pumice. Slightly acidic to neutral pH.
FertilizerQuarter-strength balanced liquid fertilizer monthly in spring–summer; none or very light feeding in fall–winter.
HumidityPrefers moderate to high humidity (50–70%), but adapts to typical indoor levels if watering is well managed.
