Dormancy/Rest Period
October-DecemberPlant appears inactive with little to no new growth; pseudobulbs may appear slightly shriveled; flower spikes begin developing
Reduce watering dramatically; provide cooler nighttime temperatures (55-60°F); maintain bright light; this 2-3 month period is crucial for flower initiation
Early Growth & Flowering
January-MarchNew shoots emerge from base; tall flower spikes develop with buds forming; pseudobulbs begin swelling
Increase watering and humidity as growth accelerates; provide bright light; support tall spikes with stakes if needed; maintain warm temperatures (65-75°F)
Peak Flowering
February-AprilMultiple fragrant flowers open sequentially; blooms display yellow-green to purple coloring with patterned lips; long-lasting flowers
Maintain consistent moisture and humidity; continue bright light; enjoy fragrance typically strongest in morning hours; protect from drafts
Post-Flowering & Active Growth
April-AugustFlowers fade and drop; new leaves emerge vigorously; pseudobulbs develop and thicken significantly
Increase watering and fertilizing; provide warm temperatures (70-80°F) and high humidity; apply balanced orchid fertilizer every 1-2 weeks
Late Growth & Preparation for Dormancy
August-OctoberGrowth rate slows; pseudobulbs mature and harden; plant gradually transitions toward dormancy
Begin reducing watering in late September; reduce nitrogen fertilizer; maintain warm temperatures but allow slight nighttime cooling; move to brighter light
