Dormancy/Rest
3-4 months (typically winter)Plant enters cool, dry rest period with reduced leaf growth; foliage may appear less vibrant
Provide cooler temperatures (55-60°F), reduce watering, and lower humidity slightly; critical for flower bud initiation
Active Growth
4-6 monthsNew leaves and pseudobulbs emerge; rhizome extends with visible growth points
Increase watering and humidity; apply balanced orchid fertilizer every 2-3 weeks; maintain warm temperatures (65-75°F)
Bud Development
2-3 monthsFlower spikes emerge from the base of pseudobulbs; buds form along the spike
Maintain consistent temperatures and humidity; avoid moving plant; support spikes with stakes if needed; continue regular fertilizing
Flowering
6-12 weeksFragrant, patterned flowers open progressively along spike; blooms are long-lasting and aromatic
Maintain cooler nights (55-60°F) to extend bloom duration; reduce nitrogen fertilizer; continue regular watering
Post-Bloom Recovery
4-8 weeksFlowers fade and drop; plant begins new growth cycle
Gradually shift toward rest period with cooler temperatures and reduced watering; prepare for next dormancy cycle
