Growing Conditions
Bulbophyllum facetum is cultivable with attention to its tropical preferences:
Light: Low to moderate, indirect light (1,000-2,000 foot-candles). It favors shade or filtered light, avoiding harsh sun.
Temperature: Warm, 65°F-85°F (18°C-29°C) during the day, with a slight drop at night. It’s not frost-tolerant.
Humidity: High, 70%-85%. It benefits from misting or a humidifier in dry climates.
Watering: Keep the medium (e.g., bark, sphagnum moss, or mounted on cork) evenly moist but well-drained. Overwatering can rot its fine roots.
Air Movement: Critical to prevent fungal issues and mimic its breezy forest habitat.
Fertilizer: Use a diluted orchid fertilizer (e.g., 1/4 strength) biweekly during active growth (spring-summer).
Care Tips
Mounting vs. Pots: It does well mounted on plaques (e.g., cork or tree fern) to showcase its creeping habit and ensure drainage. If potted, use a small container with a loose, airy mix. We grow in loosely packed sphagnum moss for drainage and moisture retention.
Root Sensitivity: Avoid overhandling—its fine roots dislike disturbance.
Pest Watch: Check for spider mites or scale, common pests in humid setups, though it’s not especially prone.
