Vegetative Growth
1-2 yearsPseudobulbs elongate, thin grass-like leaves develop, plant gradually increases in size and vigor
Maintain consistent watering and humidity; ensure excellent air circulation with a small fan; apply diluted orchid fertilizer every 1-2 weeks during active growth
Pre-Flowering
4-8 weeksMature pseudobulbs develop and harden; flower spikes begin to emerge from leaf axils
Reduce water slightly to encourage blooming; maintain bright light; apply phosphorus-rich fertilizer to support flowering; ensure cool night temperatures (10-15°C difference from day)
Flowering
4-8 weeksDelicate, star-shaped white or pale pink flowers bloom, typically fragrant (especially evening fragrance); flowers are long-lasting
Do not repot during blooming; maintain consistent conditions; support flower spikes with gentle ties if needed; enjoy the fragrance, especially in evening
Post-Flowering Rest
4-6 weeksFlowers fade and drop; plant prepares for next growth cycle; pseudobulbs mature
Reduce watering and fertilizing frequency slightly; maintain bright light and good air circulation; allow a brief (2-3 week) cool, dry rest period to trigger next flowering cycle
