Growth Stages
Dormancy/Rest Period
6-8 weeks (typically fall/winter)Plant appears inactive with no new growth; existing leaves remain healthy and green
Reduce watering; maintain temperatures 55-65°F at night to trigger blooming; reduce fertilizer frequency to monthly
Spike Development
4-6 weeksFlower spike emerges from leaf axil; small nodes visible along the developing spike
Stake spike loosely if needed; maintain humidity 50-70%; continue cool nights; do not disturb spike or plant location
Budding
3-4 weeksMultiple buds form along spike; buds swell and develop color
Maintain consistent temperature (70-80°F daytime); increase humidity to 60-80%; provide bright light; fertilize every 2 weeks with orchid formula
Flowering
8-16 weeks (flowers last 2-3 months)Elegant, moth-shaped flowers open sequentially along spike; flowers range in color from white and pink to yellow and burgundy
Maintain 65-75°F nights; avoid temperature fluctuations; water when bark is nearly dry; do not move plant; mist nearby (not directly on flowers)
Post-Bloom & Growth
4-8 weeks before next rest cycleFlowers fade and drop; new leaves develop; plant may develop secondary spikes from nodes
