Growth Stages

1

Establishment

2-4 weeks

New plant develops root system and acclimates to growing conditions; may appear dormant initially

Avoid repotting immediately; let roots establish first. Maintain consistent warmth (65-75°F) and humidity. Water moderately.

2

Vegetative Growth

6-9 months

Plant produces new pseudobulbs and foliage; green shoots elongate from base

Provide bright light and warm temperatures (75-85°F daytime, 60-65°F nighttime). Fertilize every 2 weeks with balanced orchid fertilizer. Water regularly as growth is active.

3

Bud Formation

4-6 weeks

Flower spike emerges from base of mature pseudobulb; buds form along spike

Maintain bright light and slightly cooler nights (55-60°F) to promote flowering. Reduce nitrogen; increase phosphorus/potassium with bloom fertilizer. Keep humidity high.

4

Flowering

4-8 weeks

Large, fragrant burgundy-red flowers open sequentially on spike; blooms last 4-8 weeks

Avoid moving plant or changing light conditions. Provide excellent air circulation. Reduce watering slightly but maintain humidity. Enjoy fragrance, especially in morning and evening.

5

Post-Bloom Rest

2-4 weeks

Flowers fade and drop; plant enters brief dormancy before next growth cycle

Reduce watering frequency slightly. Maintain warm temperatures and bright light. Resume regular feeding to support next growth cycle after 2-3 weeks.
