Establishment
2-4 weeksYoung plant adjusting to growing environment with 2-4 thin leaves and minimal root development
Keep humidity moderate (50-70%), maintain consistent warm temperatures (65-75°F), and water sparingly until new roots emerge. Avoid fertilizing
Vegetative Growth
6-12 monthsPlant develops 4-8 slender, reed-like leaves and establishes a robust root system; no flowers present
Maintain bright indirect light, regular watering schedule, and begin weak weekly fertilization (quarter-strength orchid fertilizer). Support humidity at 50-70%
Pre-Flowering
2-4 weeksPlant reaches mature size with 8-12 leaves; flower spikes begin to emerge from leaf axils
Provide cooler night temperatures (55-60°F) to trigger blooming; reduce nitrogen and increase phosphorus in fertilizer to promote flowering
Flowering
8-16 weeks (can reflower with proper dormancy)Multiple cascading spikes of small, delicate pink flowers bloom; spikes may branch and produce dozens of individual florets
Reduce fertilizer to every 2-3 weeks; maintain humidity and bright light without direct sun; avoid moving the plant to prevent bud drop
Post-Flowering & Rest
4-8 weeksFlowers fade and drop; plant enters a brief rest period with reduced vigor
Cut spent flower spikes above dormant eye nodes if desired to encourage secondary flowering, or remove entirely. Reduce watering slightly and maintain cooler temps (60-70°F) for 4-6 weeks
