Dormancy/Emergence
2-3 months (late winter to early spring)Plant appears mostly dormant with visible pseudobulbs at soil level; new shoots begin emerging in spring
Reduce watering and allow light drying between waterings; maintain temperatures above 60°F; ensure good air circulation
Vegetative Growth
4-6 weeksNew shoots and leaves develop vigorously; multiple stems emerge from pseudobulbs; foliage grows tall and upright
Water regularly, maintain high humidity (60-70%), fertilize bi-weekly with balanced orchid fertilizer (1/4 strength), ensure bright indirect light
Budding & Flowering
6-12 weeksTall flower spikes emerge from base of plant with multiple buds along the rachis; primrose-yellow flowers with pink/red centers open sequentially
Maintain warm temperatures (70-85°F), ensure consistent moisture, increase humidity to 60-70%, reduce nitrogen fertilizer, support tall spikes with staking if needed
Post-Flowering
3-4 weeksFlowers fade and drop; spent flower spikes may persist or be removed; plant energy redirects to pseudobulb formation
Cut spent flower spikes just above the lowest node if desired for reblooming potential, or remove entirely; continue regular watering and fertilizing
Pseudobulb Maturation
8-10 weeksNew pseudobulbs develop and enlarge as plant stores energy; older leaves may yellow and drop naturally
Maintain warm growing conditions, continue moderate watering and fertilizing, reduce frequency toward fall/winter dormancy period
