Growth Stages

1

Seedling/Young Plant

3-6 months

Tiny plantlets with minimal roots and 1-2 small leaves developing from seed flask or nursery pot

Keep in high humidity (70-80%) under bright shade. Use fine, moisture-retentive orchid mix. Repot carefully when roots emerge. Avoid direct air movement initially.

2

Vegetative Growth

12-18 months

Plant develops multiple pseudobulbs and a fan of strap-like, olive-green leaves; compact rosette formation

Maintain warm temperatures (65-80°F day, 55-65°F night). Feed with diluted orchid fertilizer (1/4 to 1/2 strength) every 1-2 weeks during growing season. Ensure good air circulation.

3

Bud Formation

4-8 weeks

Small flower spikes emerge from leaf axils or base of pseudobulbs; tiny green buds appear along the spike

Provide slight temperature drop in winter (cooler nights around 50-55°F) to trigger blooming. Reduce watering slightly but maintain humidity. Avoid moving plant once buds form.

4

Flowering

6-12 weeks

Delicate, olive-green and cream-colored flowers open on arching or upright spikes; flowers are fragrant and often spotted or striped

Maintain stable conditions; avoid temperature swings. Continue moderate watering and humidity. Flowers last 6-12 weeks. Support spikes if needed with small stakes.

5

Post-Bloom Rest

8-12 weeks

Flowers drop and spike remains on plant or dries; plant focuses energy on root and pseudobulb development

Cut spent spikes at base once flowers fade. Reduce watering slightly and resume normal fertilizing. Prepare for next growth cycle with cooler winter rest.
