Pseudobulb Sprouting
2-3 weeksNew growth emerges from pseudobulb base; young shoots appear with first true leaves unfurling
Maintain warm temperatures (70-85°F), consistent moisture, and bright indirect light; mist regularly to encourage growth
Vegetative Growth
4-8 weeksMultiple leaves develop from pseudobulb; plant establishes robust foliage; new pseudobulbs begin forming
Provide regular fertilization (balanced orchid fertilizer at half strength), maintain humidity, ensure good air circulation
Inflorescence Development
3-4 weeksFlower spikes emerge from leaf axils; buds form along spike; plants may produce multiple spikes simultaneously
Support spikes with stakes if needed; maintain consistent watering; apply high-phosphorus fertilizer to promote flowering
Flowering
6-10 weeks per spike cyclePurple flowers with yellow centers open sequentially along spike; blooms are long-lasting, often 2-3 weeks per flower
Reduce fertilizer slightly; maintain cool nighttime temperatures (60-70°F) to extend bloom duration; ensure good air circulation to prevent fungal issues
Rest/Dormancy
2-4 weeks between bloom cyclesFlower spikes fade and can be removed; plant may slow growth temporarily; new vegetative growth resumes
Remove spent spikes at base; reduce watering slightly; provide cooler temperatures (65-75°F) for 2-4 weeks to encourage reflowering
