Growth Stages

1

Seedling/Young Plant

6-12 months

Tiny plantlet with 1-3 small leaves; very delicate and slow-growing

Keep in humid, shaded conditions with minimal fertilizer. Use distilled water. Repot carefully when roots begin emerging from medium.

2

Vegetative Growth

2-3 years

Plant develops multiple aerial roots and new leaves along the monopodial stem; stem elongates upward

Apply balanced orchid fertilizer (e.g., 20-20-20) weekly at half strength during active growth. Maintain warm temperatures (70-85°F day, 65-75°F night). Provide bright light and high humidity.

3

Pre-flowering/Maturity

2-4 months

Plant reaches 12-24 inches tall with multiple leaves spaced along the stem; visible flower spikes begin to emerge

Shift to slightly higher phosphorus fertilizer (e.g., 6-30-30) to encourage blooming. Ensure 10-15°F temperature drop between day and night. Reduce nitrogen to promote bud set.

4

Flowering

4-8 weeks

Arching flower spikes emerge with multiple waxy, fragrant flowers in white with pink or purple-tinged lips; blooms last 4-8 weeks

Continue bright light and high humidity. Maintain consistent moisture but avoid water on open flowers. Support heavy flower spikes with stakes if needed. Fragrance is strongest in morning and evening.

5

Post-flowering/Rest

2-4 weeks

Flowers fade and drop; plant enters a brief rest period before resuming vegetative growth

Reduce watering slightly and lower fertilizer frequency. Maintain warm temperatures. New growth typically resumes within 4-8 weeks.
