Dormancy
4-8 weeks (winter, typically)Plant rests with minimal growth; pseudobulbs may appear wrinkled or slightly shriveled
Reduce watering significantly but do not allow complete drying. Maintain cooler temperatures (55-65°F nights). This rest period triggers blooming.
Growth Phase
4-6 monthsNew pseudobulbs and leaves emerge; plant shows active vegetative growth
Water regularly, maintain humidity, provide bright light, and resume normal feeding schedule. Support new growth with weak liquid orchid fertilizer (1/4-1/2 strength) every 1-2 weeks.
Bud Development
2-4 weeksFlower buds emerge from the sheath at the base of the newest pseudobulb or develop at leaf nodes
Maintain consistent temperatures, avoid moving the plant, ensure stable humidity (60-70%), and provide excellent air circulation. Continue light feeding.
Flowering
4-8 weeksLarge, showy blooms open in shades of purple, pink, white, red, or yellow; flowers are often fragrant
Do not move the plant or alter conditions abruptly. Maintain consistent watering and humidity. Flowers last 4-8 weeks with proper care. Enjoy the fragrance.
Post-Flowering
2-4 weeksFlowers fade and fall; plant transitions back to rest or growth phase
Allow a brief rest period (cooler nights, slightly reduced watering) before resuming regular care. Repot if needed after blooming cycle completes.

Harvest Tips
Cattleyas are not harvested in the traditional sense; instead, cut flower spikes for display when blooms are fully open. Use sterile scissors or pruners to cut stems at the base of the spike, just above a node. Blooms typically last 4-8 weeks in a vase with fresh water changed every 2-3 days. The fragrance is often strongest in morning hours.
Fun Facts
