Growth Stages

1

New Growth & Sprouting

4-6 weeks

Emerges from dormancy with new leaf buds along the pseudobulb; fresh green shoots develop in spring

Gradually increase watering as new growth appears; provide bright light and warm temperatures (65-75°F nights); begin fertilizing at half-strength weekly

2

Vegetative Growth

6-8 weeks

Pseudobulbs elongate and produce 4-6 lanceolate leaves; plant establishes foliage for the season

Maintain consistent watering; provide high humidity; use balanced orchid fertilizer (10-10-10) weekly; ensure good air circulation; support new canes if needed

3

Dormancy/Flowering Preparation

8-12 weeks

Plant enters autumn dormancy; foliage matures and plant conserves energy; flower buds begin forming along the canes

Reduce watering significantly—allow substrate to dry between waterings; lower nighttime temperatures to 55-60°F to trigger blooming; reduce fertilizing; maintain high light levels

4

Blooming

4-8 weeks (typically January-March)

Spectacular clusters of large white flowers with contrasting dark centers appear along the canes; blooms are highly fragrant, especially in morning and evening

Maintain dormant conditions; water sparingly; provide bright light; avoid moving plant; enjoy fragrance; flowers can last 4-6 weeks; stop fertilizing

5

Post-Bloom Rest & Recovery

2-4 weeks

Flowers fade and fall; plant may produce some new basal growth while still in dormancy before full spring growth resumption

Gradually increase watering; raise temperatures to 65-75°F; resume regular fertilizing; prune any dead or weak pseudobulbs; repot if needed
