Growth Stages

1

Seedling/Young Plant

6-12 months

Tiny plantlets with 2-3 leaves, developing root system

Keep in humid environment (70%+ humidity), provide dappled light, use fine-grade bark mix, water gently but frequently

2

Vegetative/Cane Development

6-18 months

Plant develops characteristic pseudobulbs or canes with multiple leaves spaced along stem

Increase light gradually, maintain warm temperatures (65-75°F nights, 75-85°F days), fertilize bi-weekly with dilute orchid fertilizer, ensure good air circulation

3

Dormancy/Rest Period

4-8 weeks (typically autumn-winter)

Growth slows or stops, leaves may yellow slightly, plant appears less vigorous

Reduce watering significantly, lower temperatures (55-65°F nights), reduce fertilizer, maintain bright light, allow 4-8 week rest period to initiate flowering

4

Flowering

2-4 weeks bloom development, flowers last 2-12 weeks depending on species

Flower buds emerge from leaf axils or stem nodes; buds swell and open over 1-3 weeks into full blooms

Maintain consistent temperatures, avoid moving plant, increase humidity, provide bright light, use low-nitrogen fertilizer or stop feeding, water less frequently but don't dry out completely

5

Post-Bloom

Variable, typically 2-4 weeks before growth resumes

Flowers fade and drop, plant resumes vegetative growth or enters dormancy

Remove spent flower stems above the first or second node to encourage branching, resume regular watering and feeding, maintain good light levels
