Growth Stages

1

Establishment

4-8 weeks

Young plant with small rosette of 4-6 thin, linear leaves; roots beginning to develop

Maintain high humidity (70-80%); provide bright indirect light; avoid disturbing roots; monitor for acclimation stress

2

Vegetative Growth

6-12 months

Plant develops additional leaf pairs, creating a fuller rosette; aerial roots become more prominent and visible

Continue consistent watering; fertilize weekly at half strength with orchid fertilizer; maintain warm temperatures (70-75°F daytime); ensure good air circulation

3

Maturation & Flowering Preparation

2-4 months

Plant reaches adult size with established rosette; may show increased root development; cooler winter period may trigger blooming cycle

Provide slight temperature drop in winter (65-70°F); reduce watering slightly; maintain bright light; reduce nitrogen fertilizer in favor of phosphorus

4

Flowering

2-4 weeks per flowering cycle

Produces tiny, fragrant white flowers in loose terminal inflorescences; flowers are delicate with long, thin petals; blooms typically last 2-4 weeks

Maintain consistent humidity and temperature; avoid moving plant; continue regular misting; do not fertilize heavily to avoid dropping flowers; enjoy fragrance, especially in evening

5

Post-Flowering & Rest

2-6 weeks

Flowers fade and drop naturally; plant enters brief rest period before resuming growth or repeat blooming

Reduce watering slightly; maintain humidity; resume regular fertilizing; remove spent flower stems; plant may rebloom within weeks or months
