New Growth
4-6 weeksFresh green shoots emerge from the base of pseudobulbs in spring and summer
Increase watering and fertilizing (every 1-2 weeks at half-strength). Provide bright light and good air circulation.
Vegetative Development
6-8 weeksPseudobulbs enlarge and new leaves develop; plant builds energy reserves
Continue regular watering and weekly dilute fertilizer. Ensure consistent warm temperatures (65-80°F daytime, 55-65°F nighttime).
Dormancy/Cooling Period
4-6 weeks (late summer to early fall)Growth slows in late summer; plant enters a rest phase to trigger flowering
Reduce watering slightly. Maintain a 10-15°F temperature drop between day and night to initiate flower buds.
Blooming
3-4 weeks (autumn to early winter)Tall inflorescences emerge with 3-5 large rose-purple, fragrant flowers per stem
Do not move plant while blooming. Maintain moderate watering. Flowers last 3-4 weeks or longer.
Post-Bloom Rest
2-4 weeksFlowers fade and fall; plant enters brief rest before resuming growth
Reduce watering and fertilizing. Repot if needed (every 2-3 years after flowering). Gradually increase care as new growth appears.
