(Thongchai Gold x Udom Yellow)

Description Type: Epiphytic orchid Growth Habit: Sympodial, with tall, upright pseudobulbs Leaves: Long, narrow, and leathery Flowers: Bright yellow to golden blooms, often with a contrasting lip, appearing along the upper portion of canes Blooming Season: Typically once or twice a year, depending on growing conditions �� Light Requirements Bright, indirect light is ideal. A few hours of gentle morning sunlight is beneficial, but avoid harsh midday sun to prevent leaf burn. Indoor growers can use east- or south-facing windows with sheer curtains. ��️ Temperature & Humidity Day: 25–30°C (77–86°F) Night: 15–20°C (59–68°F) Tolerates short periods of higher or lower temperatures. Humidity: 50–70% is ideal. Use humidity trays or a humidifier if grown indoors. �� Watering Water thoroughly when the potting medium is almost dry. Avoid waterlogging to prevent root rot. Reduce watering slightly during cooler or less active growth periods. Always allow for good drainage. �� Potting Medium Use a well-draining mix such as medium-grade orchid bark, charcoal, and perlite. Repot every 1–2 years, preferably after blooming or when the medium starts to break down. �� Fertilizing Use a balanced orchid fertilizer (20-20-20 or similar) every 2 weeks during active growth. During the blooming season or cooler months, reduce feeding to once a month or use a bloom-boost formula (higher phosphorus). ✂️ Pruning & Maintenance Remove spent flower spikes once fully dried. Trim dead or yellowing leaves with sterile scissors. Keep air movement around the plant to prevent fungal or bacterial issues. �� Blooming Tips Provide a slight drop in nighttime temperatures in the fall to trigger blooming. Maintain consistent light and avoid moving the plant frequently once a flower spike appears.
