Growth Stages

1

New Growth

4-8 weeks

Young shoots emerge from pseudobulbs; tender light green foliage unfurls

Maintain consistent moisture and warmth (65-75°F); provide bright indirect light; mist regularly

2

Vegetative Growth

Several months to 1 year

Pseudobulbs and leaves mature; plant develops full foliage; new growths continue intermittently

Regular watering, weekly orchid fertilizer at quarter-to-half strength during active growth; ensure good air circulation

3

Flowering Preparation

4-6 weeks

Pseudobulbs mature and harden; flower spikes begin to emerge near base of new growth

Slightly reduce watering; maintain cool nights (50-60°F) to trigger blooming; reduce nitrogen fertilizer, increase phosphorus

4

Flowering

2-4 weeks

Deep red to maroon flowers with contrasting yellow lips open along spike; flowers are fragrant

Maintain consistent conditions; do not move plant; continue careful watering; flowers last 2-4 weeks

5

Post-Bloom Rest

3-8 weeks

Flowers fade and drop; plant enters semi-dormant period

Reduce watering slightly; maintain cooler temperatures; resume regular feeding when new growth appears
