Growth Stages

1

Establishment

2-4 weeks

Plant adjusts to new conditions with initial root development; small new growth appears at the base

Maintain high humidity (50-70%), avoid repotting for 2-3 weeks, provide bright indirect light, and water conservatively

2

Vegetative Growth

4-8 months

New pseudobulbs develop with 2-3 leaves each; plant builds strength and size with multiple growths emerging

Increase watering frequency as growth accelerates, apply monthly orchid fertilizer at half strength, maintain warmth (70-80°F day, 60-70°F night), and provide bright light

3

Bud Development

3-6 weeks

Flower spikes emerge from the base of new pseudobulbs; buds begin to swell and show color

Maintain consistent watering, continue fertilizing, provide cool nights (55-65°F) to encourage budding, avoid moving the plant, and ensure 12-14 hours of light

4

Blooming

6-10 weeks

Flowers open fully, displaying deep purple coloration with distinctive markings; blooms are delicate and long-lasting

Reduce nitrogen fertilizer, switch to higher phosphorus formula to extend bloom, maintain humid conditions, ensure good air circulation, and keep plant away from ethylene sources

5

Post-Bloom Dormancy

4-6 weeks

Flowers fade and drop; plant enters a rest period with minimal new growth

Reduce watering significantly, decrease fertilizer frequency to monthly, provide cooler temperatures (60-70°F), and maintain bright light to promote next growth cycle
