Growth Stages

1

Seedling/Juvenile

6-12 months

Tiny plantlets with minimal root development and 1-2 small leaves developing

Keep in high humidity (70-80%), provide bright indirect light, maintain warm temperatures (65-75°F), fertilize weakly and frequently

2

Vegetative Growth

1-2 years

Plant develops multiple small leaves arranged in clusters, root system expands, pseudobulbs begin to form

Maintain consistent moisture and humidity, provide warm conditions, increase air circulation, fertilize every 2 weeks with diluted orchid fertilizer

3

Pre-Flowering/Maturation

6-12 months

Plant reaches adult size with established pseudobulbs, foliage becomes darker and more robust, flower buds initiate

Provide slight winter cooling (60-65°F) to induce flowering, reduce watering slightly, maintain high humidity, continue regular fertilizing

4

Flowering

4-8 weeks per flower; sequential blooming may extend season

Distinctive star-shaped flowers emerge with long, hair-like sepals and complex patterning; flowers may appear sequentially

Maintain consistent temperatures and humidity, avoid moving plant, mist around (not on) flowers, continue gentle watering, reduce fertilizer

5

Post-Flowering/Rest

2-4 weeks

Flowers drop, plant may enter brief rest period before new growth initiates

Reduce watering slightly for 2-3 weeks, maintain warm temperatures and humidity, resume regular fertilizing as new growth appears
