Growth Stages

1

Dormant/Rest

4-8 weeks (typically winter)

Plant reduces active growth, pseudobulbs mature and harden. Minimal new growth visible.

Reduce watering and fertilizer; maintain cooler temperatures (55-65°F nights); provide bright light; this rest period is essential for flowering

2

New Growth

6-8 weeks

Emergence of new shoots and pseudobulbs begins; fresh green growth visible at base of plant.

Resume regular watering and feeding with balanced orchid fertilizer; maintain warmth (65-75°F nights); ensure good air circulation

3

Pseudobulb Development

8-12 weeks

New pseudobulbs expand and mature, developing characteristic shape and texture; leaves elongate and harden.

Continue regular watering and weekly dilute fertilizer application; support tall growth with staking if needed; maintain high humidity

4

Flowering

4-8 weeks (blooming period)

Flower spikes emerge from base of mature pseudobulbs, developing buds that open into large, fragrant blooms with vibrant coloring.

Provide cooler nights (10-15°F drop from day temperature) to trigger blooming; reduce nitrogen fertilizer; do not move plant once buds appear; maintain consistent watering

5

Post-Bloom

2-4 weeks

Flowers fade and drop; new vegetative growth may begin or plant enters dormancy depending on season.

Allow spent flower spike to dry naturally before removing; continue appropriate watering schedule; gradually transition to dormancy if entering rest period
