Dormancy/Rest
4-8 weeks, typically winterPlant appears inactive with minimal growth; pseudobulbs are plump but no new shoots emerge.
Reduce watering and fertilizing. Provide cooler nighttime temperatures (55-60°F) for 4-6 weeks to trigger flowering. Maintain bright light.
Growth/Vegetative
3-4 months, spring to early summerNew pseudobulbs and leaves develop; plant becomes more active. Green growth is vigorous.
Resume regular watering and fertilizing every 2 weeks at half-strength (balanced orchid fertilizer 20-20-20). Increase humidity and provide good air circulation.
Bud Formation
2-4 weeksFlower spikes emerge from the base of new pseudobulbs; tiny buds appear along the spike.
Do not move the plant; maintain consistent light, temperature, and humidity. Reduce nitrogen fertilizer; shift to bloom-promoting formula (higher phosphorus/potassium, e.g., 10-30-20).
Flowering
4-8 weeks or longer depending on conditionsDelicate red flowers with spotted patterns open in succession along sprays. Each flower lasts 2-4 weeks.
Maintain cool nighttime temperatures (55-65°F) to extend bloom longevity. Continue watering carefully at root level to avoid wetting flowers. Reduce fertilizer or use 0-10-10 low-nitrogen formula.
Post-Bloom
2-3 weeksFlowers fade and drop. Plant enters decline phase before dormancy or transitional rest period.
Continue watering and light. Once spike becomes brown/woody, it may be cut off at the base or left for secondary spikes. Gradually reduce watering to prepare for dormancy.
