Care Guide

1. Light:

• Requires bright, filtered light, ideally 50–70% sunlight.

• Can tolerate some direct morning sun; avoid strong midday sun to prevent leaf burn.

2. Temperature:

• Day: 75–85°F (24–29°C)

• Night: 60–70°F (15–21°C)

• Sensitive to frost and prolonged cold; keep above 55°F (13°C).

3. Humidity:

• Prefers 60–80% humidity.

• Mist regularly if air is dry, but ensure good air circulation to avoid fungal infections.

4. Watering:

• Water thoroughly, allowing roots to partially dry between watering.

• In summer or hot climates, water every 1–2 days; in winter, reduce frequency.

• Avoid letting roots sit in stagnant water.

5. Fertilizer:

• Use a balanced orchid fertilizer (20-20-20) at half strength every 1–2 weeks during active growth.

• Reduce feeding during dormancy or slower growth periods.

6. Mounting/Potting:

• Can be grown in hanging baskets, mounted on slabs, or in pots with coarse bark or charcoal media.

• Roots need excellent air circulation to thrive.

7. Flowering:

• Typically blooms in spring or summer.

• Flowers last 2–3 weeks and appear on upright spikes from the base of the stem.
