🌱 How to Care for Jewel Orchid to Prevent Gray Mold (Botrytis Blight)?

💧 How to Water

Water approximately once a week, allowing the top inch of soil to dry between waterings. Use lukewarm distilled or filtered water. Reduce watering in winter to every 2-3 weeks. Never let the plant sit in waterlogged soil as the rhizomes are prone to rot.

☀️ Lighting

Provide low to moderate indirect light. An east-facing window with gentle morning sun is ideal. Avoid direct sunlight, which will scorch the leaves and fade their striking coloration. This orchid naturally grows on the forest floor and tolerates shaded conditions well.

🪴 Ideal Soil

Use a well-draining orchid mix with peat moss or coco coir, perlite, and orchid bark. A slightly acidic to neutral pH (6.0-8.0) is ideal. Unlike epiphytic orchids, Ludisia discolor grows in soil and prefers a consistently moist but never waterlogged growing medium.
