Increase watering and humidity as growth resumes. Begin fertilizing at half strength weekly. Keep warm (65-75°F).
Vegetative Growth
8-12 weeksPseudobulbs enlarge with 2-3 long, lanceolate leaves; plant builds stored energy.
Maintain consistent moisture and humidity. Feed weekly with orchid fertilizer. Provide bright light but protect from intense sun.
Bloom Preparation
4-8 weeksFlower spikes begin to emerge from leaf axils or base of pseudobulbs, elongating slowly.
Maintain strong indirect light and warm temperatures (60-75°F). Continue regular watering and feeding.
Flowering
2-4 weeks per spikePendulous spikes display 4-8 fragrant white flowers with brown or tan markings and a prominent lip; blooms last 2-4 weeks.
Reduce fertilizer; use diluted blooming formula. Maintain 60-70°F nights. Keep humidity high but avoid wetting flowers.
Post-Bloom Rest
