Dormancy
2-3 monthsPlant enters deciduous dormancy in late fall-early winter, dropping leaves from pseudobulbs; pseudobulbs appear bare and withered
Drastically reduce watering; provide cooler temperatures (55-60°F); minimal fertilization; maintain humidity but allow medium to dry out more
Budbreak & Flowering
4-8 weeksNew flower spikes emerge from base of pseudobulbs in late winter-early spring; fragrant flowers open in succession
Resume moderate watering as buds form; maintain warmth (65-75°F); provide bright light; do not move plant during this critical phase
Vegetative Growth
4-6 monthsNew leaves and tall pseudobulbs develop through spring and summer; plant is lush and actively growing
Water regularly; fertilize every 2 weeks with diluted orchid fertilizer; maintain warmth (70-80°F) and humidity; increase light gradually
Maturation
2-3 monthsPseudobulbs reach full size and foliage matures; plant begins to slow growth in late summer-fall
Maintain consistent care but reduce fertilizer gradually; provide slight temperature drop (5-10°F cooler nights); continue adequate watering
Preparation for Dormancy
2-3 weeksPlant begins dropping leaves; growth slows significantly; pseudobulbs firm up and mature
Gradually reduce watering; stop fertilizing; provide cooler temperatures and drier conditions; reduce watering frequency to prepare for dormancy
