Growth Stages

1

Seedling

6-12 months

Tiny plantlets emerge from seed with minimal roots and first true leaves developing

Provide high humidity, bright indirect light, and consistent moisture; keep in humid propagation environment; use fine orchid media

2

Vegetative Growth

12-18 months

Plant develops pseudobulbs and multiple leaves; forms small rosettes of foliage

Maintain warm temperatures (65-75°F); ensure high humidity; fertilize weekly with diluted orchid fertilizer; increase light gradually

3

Pre-flowering

2-3 months (typically autumn)

Mature pseudobulbs develop; plant shows signs of dormancy preparation with slight temperature/light changes

Provide cooler nights (10-15°F drop) to trigger blooming; reduce watering slightly; maintain bright light

4

Flowering

December-February (winter)

Arching inflorescences emerge with multiple small, scarlet-red fragrant flowers; blooms are delicate and graceful

Maintain stable conditions; avoid handling inflorescences; provide bright indirect light; continue regular watering; flowers last 3-4 weeks

5

Post-flowering Rest

4-6 weeks

Flowers fade; plant enters recovery phase with reduced metabolic activity

Reduce watering frequency slightly; maintain humidity; continue bright light; resume regular fertilization after blooms drop
