Growing Conditions
Soil
Growth Stages
New Growth / Vegetative
4-6 monthsEmergence of new shoots and pseudobulbs from the rhizome; leaves unfold progressively and develop mature coloration
Maintain consistent warmth (65-75°F), provide bright light, increase watering and humidity; apply balanced fertilizer weekly at half-strength
Maturation
2-4 monthsPseudobulbs reach full size and harden off; new leaves mature completely; plant builds energy reserves
Maintain warm temperatures, provide excellent drainage, continue fertilizing but gradually reduce frequency; ensure good air movement
Flowering Initiation
4-8 weeksFlower spike emerges from base of mature pseudobulb; spike elongates and develops buds along its length
Provide slight temperature drop (60-70°F nights optimal for bud development); reduce nitrogen fertilizer, increase phosphorus and potassium; maintain consistent watering
Flowering
6-12 weeks (successive blooms)Blooms open progressively, displaying large fragrant magenta, purple, or pink flowers with contrasting lip; blooms may last 2-4 weeks per flower
Maintain 60-75°F temperatures, bright light, and good air circulation; avoid overhead watering; do not move plant frequently; reduce fertilizer
Post-Flowering / Rest
4-8 weeksFlowers fade and drop; plant enters a brief rest period before resuming new growth cycles
Reduce watering slightly (but do not allow drying out); maintain temperatures around 60-65°F nights; pause fertilizing for 4-6 weeks; prepare for next growth cycle
