Dormancy/Rest
2-3 monthsPlant enters semi-dormancy with minimal new growth and requires cooler, drier conditions
Reduce watering frequency by 30-50%; maintain temperatures 55-65°F at night; provide high humidity (50-60%). This typically occurs in winter months.
New Growth/Vegetative
3-4 monthsEmerging pseudobulbs and leaves indicate active growth; new shoots and root tips visible
Increase watering frequency; apply diluted orchid fertilizer weekly (1/4 strength); maintain warm temperatures (70-80°F daytime). Ensure bright light to support healthy leaf development.
Maturation
1-2 monthsPlant develops full-sized pseudobulbs and mature leaves; growth rate slows as plant approaches blooming readiness
Maintain consistent watering and humidity (50-70%); reduce nitrogen fertilizer, increase phosphorus and potassium to encourage flowering. Continue bright light exposure.
Flowering
3-6 weeksInflorescences emerge with characteristic small, intricate flowers in reds, yellows, browns, and combinations with spotted or striped petals
Maintain moderate watering; do not fertilize during peak bloom to extend flower longevity (3-6 weeks). Keep temperatures consistent; avoid temperature fluctuations.
Post-Bloom
2-4 weeksFlowers fade and drop; plant begins gradual transition toward dormancy or continued vegetative growth if conditions support it
Remove spent flower spikes at base; resume regular fertilizer schedule; gradually reduce watering if dormancy period approaches.
