Growing Conditions
Soil
Growth Stages
Dormancy/Rest
December-February (post-flowering)Plant enters dormancy after flowering, with minimal new growth. Foliage remains green but growth slows significantly.
Reduce watering slightly but maintain humidity. Provide cooler nighttime temperatures (55-60°F) to encourage next season's blooms. Limit fertilizer.
Growth Phase
March-JuneNew shoots and pseudobulbs emerge as temperatures warm in spring. Leaves unfurl and root development accelerates.
Resume regular watering and fertilizing every 2 weeks with diluted orchid fertilizer. Maintain high humidity and bright light. Support new growth if needed.
Maturation
July-SeptemberPseudobulbs mature and harden; new leaves fully expand. Plant develops the structure needed to support flowering.
Continue regular watering and feeding. Provide bright light but avoid direct sun. Ensure airflow to prevent fungal issues.
Flowering
October-February (peak December-February)Flower spikes emerge from the base of new pseudobulbs, developing multiple fragrant blooms. Flowers are typically deep purple-burgundy with white-striped lips.
Maintain warm temperatures (70-75°F days, 65-70°F nights). Water carefully to avoid getting flowers wet. Reduce fertilizer; switch to phosphorus-rich formula to support blooming.
Bloom Longevity
4-8 weeks total bloom seasonIndividual flowers last 4-6 weeks; multiple blooms open progressively over several weeks, extending the display.
Maintain consistent conditions. Provide indirect light to prevent petal fade. Good air circulation extends bloom life. Remove spent flowers at the base.
