Dormancy/Rest
2-3 monthsPlant enters semi-dormant phase, typically in winter; growth slows significantly and pseudobulbs may appear slightly shriveled
Reduce watering; maintain cooler temperatures (55-65°F at night); provide bright light; withhold fertilizer
Active Growth
4-6 monthsNew shoots and pseudobulbs emerge; plant shows vigorous growth; green, upright growth canes develop
Water regularly and thoroughly; fertilize weekly with diluted orchid fertilizer (1/4 strength); maintain warmth (70-80°F); ensure high humidity
Budding & Flowering
4-8 weeksFlower buds appear along the canes; buds elongate and develop color; characteristic curved petals unfold
Continue regular watering; reduce nitrogen fertilizer; apply bloom-promoting fertilizer (higher phosphorus); maintain warmth and bright light; avoid moving plant once buds appear
Blooming
2-4 weeks per bloom cycleFlowers fully open, displaying cream or yellow petals with reddish-brown markings and long, horn-like sepals and petals; fragrant scent present
Maintain consistent conditions; water moderately; avoid water on flowers; enjoy blooms; flowers last 2-4 weeks
Post-Bloom
2-4 weeksFlowers fade and drop; plant may rest briefly before entering another growth cycle or dormancy
Cut spent flower spikes just above a node if reblooming desired, or remove completely; resume regular feeding if new growth emerges
