Vegetative Growth
2-3 yearsDevelopment of mature pseudobulbs (2-4 per plant), sturdy upright growth, and increasing foliage size
Maintain warm temperatures (70-85°F day, 60-70°F night). Provide ample bright light and good air circulation. Fertilize regularly during active growth (spring-summer) with orchid fertilizer (1/2 to 1/4 strength).
Pre-flowering/Dormancy

Reduce watering slightly. Maintain cooler nights (55-60°F) to trigger blooming. Provide maximum light. Reduce fertilizer.
Flowering
3-4 weeksLarge, showy pink to magenta flowers with frilly labellum and sweet fragrance; 1-3 flowers per spike
Maintain temperature and humidity. Avoid moving plant once buds appear. Do not allow medium to dry completely. Support flower spikes if needed. Enjoy blooms for 3-4 weeks.
Post-flowering/Recovery
2-3 weeks then ongoing growthFlowers fade and drop; plant returns to vegetative growth with new shoot emergence from base
