Growth Stages

1

New Growth

4-6 weeks

Emergence of new shoots from the base of pseudobulbs with developing leaves

Maintain consistent warmth (70-85°F), humidity, and bright light. Begin regular feeding with diluted orchid fertilizer every 1-2 weeks

2

Vegetative Growth

3-4 months

Rapid development of new pseudobulbs and leaves; plant builds energy reserves

Continue warm temperatures and frequent watering. Apply balanced orchid fertilizer (20-20-20) weekly. Ensure good air circulation with a small fan

3

Maturation

2-3 months

Pseudobulbs fully developed and leaves mature; plant prepares for flowering

Reduce watering slightly and provide cooler temperatures (60-70°F nights) for 4-6 weeks to trigger blooming. Switch to bloom-promoting fertilizer (lower nitrogen)

4

Flowering

6-12 weeks

Flower spikes emerge from pseudobulbs and develop into clusters of elegant blooms lasting 6-12 weeks

Maintain high humidity and bright light. Reduce watering slightly but do not let medium dry completely. Avoid moving the plant during spike development

5

Post-Bloom Rest

4-8 weeks

Flowers fade and drop; plant enters dormant or semi-dormant phase

Significantly reduce watering frequency. Maintain cooler temperatures (55-65°F) for 4-8 weeks. Reduce feeding or stop entirely. This rest period is crucial for next year's blooms

Harvest Tips
