LightBright, indirect light to medium shade; tolerates lower light but avoid harsh afternoon sun.
WateringKeep evenly moist; water when top 1–2 in (2–5 cm) of mix is slightly dry. Reduce in winter and avoid waterlogging.
SoilLoose, airy, well-draining mix (e.g., 1/3 orchid bark, 1/3 peat or coco, 1/3 perlite); slightly acidic to neutral pH.
FertilizerFeed at 1/4 strength with a balanced fertilizer every 4–6 weeks in spring–fall; hold in winter.

Maintenance & Notes
PruningRemove yellowing or damaged fronds at the base; tidy spent fronds and wipe leaves to reduce dust.
