Seedling/Young Plant
3-6 monthsTiny plantlets with minimal roots and 1-2 small leaves developing from seed flask or nursery pot
Keep in high humidity (70-80%) under bright shade. Use fine, moisture-retentive orchid mix. Repot carefully when roots emerge. Avoid direct air movement initially.
Vegetative Growth
12-18 monthsPlant develops multiple pseudobulbs and a fan of strap-like, olive-green leaves; compact rosette formation
Maintain warm temperatures (65-80°F day, 55-65°F night). Feed with diluted orchid fertilizer (1/4 to 1/2 strength) every 1-2 weeks during growing season. Ensure good air circulation.
Bud Formation
4-8 weeksSmall flower spikes emerge from leaf axils or base of pseudobulbs; tiny green buds appear along the spike
Provide slight temperature drop in winter (cooler nights around 50-55°F) to trigger blooming. Reduce watering slightly but maintain humidity. Avoid moving plant once buds form.
Flowering
6-12 weeksDelicate, olive-green and cream-colored flowers open on arching or upright spikes; flowers are fragrant and often spotted or striped
Maintain stable conditions; avoid temperature swings. Continue moderate watering and humidity. Flowers last 6-12 weeks. Support spikes if needed with small stakes.
Post-Bloom Rest
8-12 weeksFlowers drop and spike remains on plant or dries; plant focuses energy on root and pseudobulb development
Cut spent spikes at base once flowers fade. Reduce watering slightly and resume normal fertilizing. Prepare for next growth cycle with cooler winter rest.
