Grammatophyllum

Bulbophyllum orchids are a fascinating and diverse genus, but they do have some unique care requirements compared to more commonly grown orchids like Phalaenopsis or Dendrobium. Here’s a care guide to keep them thriving:

Bulbophyllum Orchid Care Guide

🔆 Light

• Indirect, filtered light is best.

• Avoid direct sun—too much light can scorch the leaves.

• Dappled shade mimicking forest understorey is ideal.

🌡️ Temperature & Humidity

• Warm to intermediate growers.

  • Day: 22–30°C (72–86°F)

  • Night: 15–20°C (59–68°F)

• High humidity: 60–80% is optimal.

• Ensure good air circulation to prevent fungal issues.

💧 Watering

• Bulbophyllums like to stay moist, not soggy.

• Water frequently, especially during active growth.

• Use pure water if possible (rain, distilled, or reverse osmosis), especially for sensitive species.

• Never let them dry out completely, especially those without thick pseudobulbs.

🪴 Potting & Media

• Use fine bark, sphagnum moss, or a mix depending on your environment.

• Repot every 1–2 years to avoid media breakdown.

🌱 Fertilizer

• Use a balanced orchid fertilizer  at quarter to half strength.

• Feed weekly during growing season, reduce in dormancy.

⚠️ Special Notes

• Bulbophyllum blooms can have a strong or unusual scent—some are fragrant, others smell like rotting meat to attract flies!

• Watch for rot, especially at the base—good airflow and proper watering habits help.

• Some species have creeping rhizomes—shallow, wide pots or mounts help accommodate them.
