Establishment
4-8 weeksYoung plantlet or recently potted specimen with minimal root development and few leaves
Keep humidity very high (60-70%), maintain warm temperatures (70-80°F day, 65-70°F night), provide bright indirect light, water sparingly to avoid rot as roots establish
Vegetative Growth
6-12 monthsCane-like pseudobulbs elongate, producing lance-shaped leaves along the stems; plant develops a fuller structure
Increase watering as new growth appears, apply balanced orchid fertilizer (20-20-20) weakly and frequently during active growth, maintain warm temps and high humidity, provide bright light without direct sun
Pre-Flowering
4-8 weeksPseudobulbs mature and harden off; leaf production slows; flowering buds begin to form at leaf axils
Gradually reduce winter temperatures (65-70°F nights) to trigger blooming, reduce watering slightly, shift to lower-nitrogen fertilizer (e.g., 10-20-10), maintain high humidity
Flowering
4-8 weeks per bloom cycleLong-petaled, creamy white flowers with yellow/green centers open in clusters; blooms are typically 2-3 inches across and sweetly fragrant at night
Provide gentle air circulation to support flower longevity, maintain consistent warmth and humidity, avoid moving plant while buds are developing, enjoy nighttime fragrance, water carefully around flowers
Post-Flowering & Rest
2-4 weeksFlowers fade and drop; plant may enter a brief rest period with slower growth
Remove spent flower stems if desired, maintain intermediate to warm conditions, gradually return to regular fertilizer schedule, allow brief drying between waterings, prepare for next growth cycle
