Dormancy (Winter Rest)
October-January, typically 3-4 monthsPlant enters semi-dormant state with minimal growth; existing canes remain evergreen but no new growth emerges
Reduce watering by 50%, maintain cool temperatures (50-60°F nights), provide bright light, minimize fertilizer. This cold period is essential for flower bud initiation.
Bud Break & Early Growth (Late Winter-Early Spring)
January-March, 6-8 weeksFlower buds emerge along canes, typically starting at the base and progressing upward; new growth may also begin
Maintain cool to moderate temperatures (55-70°F), increase light, resume regular watering, apply dilute orchid fertilizer every 2-3 weeks. Do not disturb buds.
Flowering
February-April, 4-8 weeks per flower spikePink or rose-colored flowers open sequentially along canes, producing a long display of fragrant blooms; flowers are long-lasting
Maintain temperatures between 60-75°F, provide ample bright light, reduce nitrogen fertilizer (use phosphorus-rich bloom formula), maintain consistent moisture without waterlogging, ensure good air circulation
Post-Bloom Growth (Spring-Summer)
April-September, 5-6 monthsNew canes develop after flowers fade; plant enters active vegetative growth with emergence of new leaves and shoots from base
Resume regular watering and feeding with balanced fertilizer (10-10-10 or similar), maintain warm temperatures (65-80°F daytime, 55-65°F night), provide ample bright light, monitor for pests during active growth
Cane Maturation (Late Summer-Early Fall)
August-October, 6-8 weeksNew canes reach full height with complete set of leaves; canes begin to harden and mature in preparation for dormancy
Gradually reduce watering and fertilizing frequency, provide cooler night temperatures (starting late August), maintain bright light, ensure good air movement to harden canes and promote bud set for next season
