Dormancy/Rest
October-DecemberPlant drops leaves in fall-winter; pseudobulbs appear shriveled as the plant directs energy to blooming and root development
Reduce watering significantly but do not let medium dry completely; maintain cool nighttime temperatures (50-55°F) to trigger flowering; reduce fertilizer
Flowering
December-MarchLarge white flowers with yellow center and sometimes pink spotting on lip emerge from leaf axils; blooms are fragrant, especially in morning
Maintain cool nights to prolong bloom duration; provide bright indirect light; avoid moving plant during bloom; use orchid bloom booster fertilizer sparingly
New Growth/Vegetative
March-JuneFresh green leaves emerge from pseudobulbs; new shoots and roots develop; plant appears vigorous and active
Increase watering and fertilize every 2 weeks with balanced orchid fertilizer; maintain warm temperatures (65-75°F daytime, 55-60°F nighttime); ensure high humidity and air circulation
Pseudobulb Maturation
June-SeptemberPseudobulbs swell and harden; leaf growth completes; plant stores energy reserves
Continue regular watering and monthly fertilizing; provide bright light; maintain humidity; monitor for pests as new tender growth attracts insects
Pre-dormancy Transition
September-OctoberLeaves yellow and drop naturally as plant prepares for rest; pseudobulbs begin to shrivel slightly
Gradually reduce watering; lower nighttime temperatures; cease or reduce fertilization; allow leaves to drop naturally without intervention
