Dormancy/Rest Period
2-3 months (typically fall/winter)Plant appears inactive with minimal new growth; canes may appear wrinkled or dull; leaves are fully mature
Reduce watering significantly; provide cooler temperatures (55-65°F nights) and lower light; this cold/dry dormancy triggers flowering
Bud Formation
4-8 weeksSmall flower buds emerge from nodes along the canes; buds gradually swell and elongate
Maintain cool nights; continue reduced watering; ensure bright light to support bud development; avoid moving plant
Flowering
4-8 weeksBlooms open in succession along the flower spike; flowers are waxy, symmetrical, and highly colorful; peak display lasts 4-8 weeks
Increase watering gradually; maintain bright light; support tall spikes with stakes if needed; avoid direct sun that may fade blooms; keep temperatures moderate
Post-Bloom/Active Growth
3-4 monthsOld flowers drop; new shoots and roots emerge from base of pseudobulbs; plant enters vigorous vegetative phase
Resume regular watering and feeding; increase humidity; maintain warm temperatures (70-85°F); provide bright, indirect light; repot if needed after flowering
Cane Maturation
2-3 months before returning to dormancyNew canes develop fully; leaves are vibrant green; mature canes may produce side shoots or keikis (baby plantlets)
Maintain consistent warmth and humidity; water regularly; feed bi-weekly with orchid fertilizer; watch for keikis to propagate
