Dormancy/Rest
2-3 months, typically winterPlant is semi-dormant with minimal new growth; pseudobulbs are plump and firm
Reduce watering and feeding; maintain cool, dry conditions (60-70°F); maintain good air circulation
New Growth/Vegetative
3-4 monthsTiny pseudobulbs and leaves emerge; plant shows signs of new rhizome growth
Increase watering and humidity; apply diluted orchid fertilizer weekly; provide bright, filtered light and good air movement
Budding/Flowering Preparation
1-2 monthsSmall flower buds form at the base of pseudobulbs; buds are extremely tiny and may be easily overlooked
Maintain consistent moisture and humidity; continue weekly fertilizing; provide cooler nighttime temperatures (55-65°F) to trigger blooming
Blooming
2-4 weeks per flower; multiple blooms possible over 4-6 weeksMiniature, fragrant flowers open; blooms are often purplish, reddish, or yellow with intricate markings; individual flowers may last weeks
Maintain humidity and air circulation; avoid getting water on delicate petals; reduce nitrogen fertilizer, increase phosphorus; provide bright light to sustain blooms
Post-Bloom/Recovery
1-2 monthsFlowers fade; plant returns to vegetative growth; older pseudobulbs may shrivel slightly as energy redirects to new growth
Return to regular watering and feeding; provide ample light and air circulation; prepare for next growth cycle
