Growth Stages

1

Young Plantlet

6-12 months

Small orchid with 2-3 leaves and developing pseudobulbs; minimal growth

Maintain high humidity (70-80%), provide bright indirect light, water moderately when medium surface dries, ensure excellent drainage

2

Vegetative Growth

12-24 months

Plant develops new pseudobulbs and leaves; full-sized plant with mature foliage

Maintain warm temperatures (65-80°F day, 60-70°F night), fertilize bi-weekly with balanced orchid fertilizer, provide bright light and good air circulation

3

Bud Initiation

4-8 weeks

New flower spikes emerge from the base of pseudobulbs; small green buds appear

Cooler nights (10-15°F temperature drop) trigger flowering; maintain humidity and bright light, reduce nitrogen fertilizer, do not disturb spikes

4

Flowering

4-8 weeks

Cascading sprays of small, golden-yellow flowers open progressively along spikes; multiple spikes may be present

Maintain 60-80% humidity, provide bright indirect light to preserve color, avoid moving plant, water carefully to not wet flowers, enjoy blooms which can last 4-8 weeks

5

Post-Flowering & Rest

4-8 weeks

Flowers fade and drop; plant enters semi-dormant period

Gradually reduce watering slightly, maintain cooler temperatures if possible (50-60°F nights), allow brief dry period between waterings, prepare for next growth cycle

Harvest Tips

Cut flowering spikes at the base with sterile pruning shears once flowers have faded completely. Some spikes may rebloom from latent buds if cut above a node, but cutting all the way to the base encourages plant energy toward next blooming cycle. Enjoy cut spikes in a vase filled with room-temperature water for 2-3 weeks indoors.
