Growth Stages

1

Dormancy/Rest

6-8 weeks (typically October-November)

Plant enters winter dormancy with reduced leaf growth; pseudobulbs are fully formed and firm

Reduce watering significantly; provide cooler nighttime temperatures (55-65°F) and bright light to trigger flowering; minimal fertilizer

2

Bud Formation & Flowering

8-12 weeks (typically December-February)

Flower spikes emerge from base of pseudobulbs; multiple large buds develop and open into fragrant blooms

Do not move plant during bud development; maintain cool nights; mist air roots; minimal watering to prevent bud drop; provide bright indirect light

3

Bloom

3-8 weeks per flower; multiple flowers bloom sequentially

Flowers are fully open, large (up to 4-6 inches), lavender-pink or white, with fragrance most pronounced in morning and evening

Enjoy flowers; maintain stable conditions; continue reduced watering; avoid temperature fluctuations; provide good air circulation

4

Post-Bloom & New Growth

Spring through early summer (3-4 months)

Spent flowers drop; new shoots emerge from base of pseudobulbs; fresh green leaves develop on new growth

Resume regular watering and feeding with orchid fertilizer (diluted); maintain warm, humid conditions (60-80°F); increase light gradually

5

Vegetative Growth & Maturation

Summer through early autumn (4-5 months)

New pseudobulbs develop and enlarge; plant builds energy reserves; leaves are full-sized and firm

Maintain warm growing conditions; regular watering and weekly diluted fertilizer; high humidity (50-70%); provide bright light; repot if needed in spring

Harvest Tips

Cattleya orchids are grown for ornamental flowers, not harvest. Cut flowers for display by cutting the spike above the node with a sterile knife when blooms are open; flowers last 3-6 weeks in a vase with orchid preservative and fresh water. Leave 2-3 nodes on the plant for potential future reblooming. For propagation, divide pseudobulbs (with 3-4 bulbs per division) only after flowering in spring; use sterile tools and orchid-specific medium.
