Dormancy/Winter Rest
2-3 months (typically November-January)Plant shows minimal growth; older pseudobulbs may lose leaves; little or no new growth is visible
Reduce watering and feeding; provide cooler temperatures (55-65°F nights) to initiate flowering; maintain bright light
Flower Initiation & Bud Development
4-8 weeksFlower buds emerge from sheath at base of new pseudobulbs; buds swell and show color as they develop
Do not disturb plant; maintain consistent temperatures; increase humidity slightly; avoid moving plant; continue reduced watering
Flowering
4-8 weeks or longerLarge, fragrant flowers open in various colors (pink, purple, white, yellow, bicolors); flowers can last 4-8 weeks per bloom
Maintain stable conditions; avoid temperature fluctuations; provide good air circulation; reduce watering slightly during bloom
Post-Flowering & Active Growth
4-6 months (February-June)Flowers fade and drop; new shoots and leaves emerge vigorously from pseudobulb base; plant enters growth phase
Resume regular watering and feeding; provide warm temperatures (70-85°F days); ensure high humidity; repot if needed in spring
Maturation
2-3 months (July-September)New pseudobulbs develop fully; leaves mature and harden off; plant accumulates energy for next flowering cycle
Maintain consistent watering and feeding schedule; provide bright light; begin to cool temperatures slightly in fall to prepare for dormancy

Harvest Tips
Cattleya orchids are grown for ornamental blooms rather than harvest in the traditional sense. Cut flowers with sharp, sterile scissors when blooms are fully open; they last 2-4 weeks in a vase. Flowers are often cut at the base of the flower spike for arrangements. Leave the pseudobulb and leaves on the plant to support future flowering.
Fun Facts
- 🌱 Cattleya orchids are named after the 19th-century British plant collector William Cattley, and they became status symbols among Victorian orchid enthusiasts, often commanding extremely high prices at auction.
- 🌱 Some Cattleya species produce fragrances that mimic pheromones of female bees, attracting male bees as pollinators in a remarkable example of plant deception in nature.
- 🌱 Cattleya orchids can live for 50+ years and will produce flowers reliably for decades, with some specimen plants being passed down through families as heirlooms.
