Dormancy/Rest
2-3 monthsPlant enters winter dormancy (November-January) with reduced growth and leaf yellowing on older canes
Reduce watering significantly; maintain cool nighttime temperatures (50-60°F); provide bright light; cease fertilizing
Bud Development & Flowering
4-8 weeksFragrant golden-yellow flowers emerge from nodes along pseudobulbs; blooms appear in clusters
Maintain cool nights (55-65°F) to trigger flowering; ensure bright light; reduce watering but don't allow complete drying; provide high humidity
Active Growth
4-6 months (spring-summer)New shoots and pseudobulbs develop from base; fresh green leaves emerge from growing canes
Water regularly and generously; apply balanced orchid fertilizer weekly; ensure warm days (70-80°F) and high humidity; improve air circulation
Maturation
2-3 months (late summer-fall)Pseudobulbs reach full size and harden off; foliage becomes darker green and more leathery
Continue regular watering and feeding; maintain bright light; gradually reduce moisture as autumn approaches to promote flowering
Regeneration
OngoingAged canes and pseudobulbs remain viable for multiple years; plant maintains basal vigor
Do not remove old canes immediately as they can produce additional flowers; monitor for new growth from base and lateral buds

Harvest Tips
Cut flower sprays for arrangements with a sterile sharp knife when blooms are fully open; cut at the base near the pseudobulb. Flowers last 4-8 weeks on the plant and 2-3 weeks in a vase with proper care. Leave old canes intact for several years as they may rebloom from lateral buds.
