Care Guide 

1. Light:

• Prefers bright, indirect light.

• Can tolerate some morning sun but avoid harsh midday sun to prevent leaf burn.

• Indoors, a north- or east-facing window or filtered light works well.

2. Temperature:

• Day: 65–75°F (18–24°C)

• Night: 50–60°F (10–16°C)

• Tolerates cooler temperatures better than tropical Vandas; avoid frost.

3. Humidity:

• Prefers 50–70% humidity.

• Mist occasionally if indoor air is dry.

• Good air circulation is important to prevent fungal issues.

4. Watering:

• Keep roots slightly moist but not waterlogged.

• Water more frequently during the growing season, reduce during cooler months.

• Allow medium or mounting surface to dry slightly between waterings.

5. Fertilizer:

• Use a diluted orchid fertilizer (½ strength) every 2 weeks during active growth.

• Reduce feeding during winter or dormant periods.

6. Mounting/Potting:

• Grows well in small pots with sphagnum moss, bark, or mounted on cork/wood slabs.

• Ensure excellent drainage and airflow around roots.

7. Flowering:

• Blooms in late winter to early spring, producing small, delicate flowers along short spikes.

• Flowers last 1–2 weeks but can appear in successive waves if conditions are good.
