Sunlight

Bright, indirect light is ideal. Direct sunlight can scorch the leaves. In its natural habitat, it grows in the upper canopy, receiving filtered light.

Watering

Water thoroughly when the potting medium is dry, reducing frequency in cooler months. Avoid waterlogged conditions, which can lead to root rot. Ensure good drainage.

Soil

Requires a very well-draining epiphytic mix, typically consisting of bark chips, charcoal, and sphagnum moss. Avoid heavy, water-retentive soils.

Temperature

Warm to intermediate temperatures are best, with a day range of 20-30°C and a slight drop at night.

Habitat

Greenhouse, Outdoor

Fertilizer

Feed with a balanced orchid fertilizer diluted to half strength every 2-4 weeks during the growing season. Reduce feeding in winter.
