Seedling/Young Plant
6-12 monthsTiny plant with 2-3 small leaves; minimal root development
Maintain high humidity (70-80%); use very fine, moisture-retentive orchid medium; keep warm (65-75°F); provide bright, filtered light; avoid direct sun
Vegetative Growth
12-18 monthsPlant develops 4-6 leaves in monopodial pattern; aerial roots emerge; plant gradually increases in size
Continue high humidity; water regularly; provide bright light; fertilize biweekly with balanced orchid fertilizer (1/4 strength); ensure good air circulation
Pre-flowering
1-3 monthsPlant reaches sufficient maturity; leaf color may deepen; inflorescence buds begin to form at leaf axils
Maintain consistent warm temperatures (70-80°F day, 60-65°F night); provide slight winter cooling if possible; reduce water slightly; continue feeding with lower-nitrogen orchid fertilizer
Flowering
3-4 weeks per flower; successive flowers over 6-8 weeksDelicate white flowers with crystalline, translucent petals and pale pink lip appear on slender inflorescences; typically 3-8 flowers per stem
Maintain humidity and air circulation; provide optimal light; water carefully to avoid water on blooms; reduce fertilizer or switch to bloom-promoting formula; protect from temperature swings
Post-flowering & Rest
Several months to next bloom cycleFlowers fade and drop; plant continues vegetative growth; may produce seed pods if pollinated
Resume regular feeding schedule; continue warm, humid conditions; remove spent inflorescences; allow brief cool period (55-60°F nights) in winter to encourage reblooming
