Care Guide

• Light: Provide bright, filtered light with gentle morning sun where conditions allow. Acclimate gradually and protect the leaves from harsh midday exposure.
• Water: Water thoroughly during active growth, then allow the open medium to approach dryness before watering again. Reduce frequency modestly when growth slows, but avoid prolonged drought.
• Humidity: Maintain moderate to high humidity with strong, consistent air circulation.
• Temperature: Grow in warm conditions and protect the plant from cold temperatures and chilling drafts.
• Growing medium: Use a sturdy basket or well-drained container with a coarse, durable orchid mix that gives the vigorous roots abundant air.
• Feeding: Fertilize regularly at a dilute concentration during active growth, flushing the medium periodically with plain water.

With bright filtered light, warmth, generous seasonal watering, and ample root space, Grammatophyllum scriptum can mature into a commanding specimen with an unforgettable floral presence.
