Cattleya Orchid

Overview

Cattleya, the classic corsage orchid, has ruffled, perfumed blooms and was the best-known orchid for a century before Phalaenopsis took over the supermarkets. Big fragrant blooms in impossible colors, a tougher constitution than its glamour suggests, and one non-negotiable demand: real light. (Cattleya.)

Origin & Natural Habitat

Tree branches of Central and South America (Brazil, Colombia especially) in bright, breezy, seasonally dry forest.

Appearance

Pseudobulbs with leathery leaves, 15-60 cm by type; blooms 8-20 cm (ruffled lips, jewel colors, many richly fragrant) lasting 2-6 weeks, once or twice a year.

Why People Grow It - Qualities & Benefits

• The most spectacular, fragrant blooms in common orchid keeping
• Tough, forgiving pseudobulb constitution
• Compact modern hybrids fit windowsills
• The classic connoisseur step after Phalaenopsis

Care

Light: The crux: bright light with some gentle sun (east or lightly shaded south window) - leaves should be light apple-green, not dark. Dark-green happy-LOOKING plants never bloom.

Water: Soak thoroughly, then dry fully - pseudobulbs store water; soggy roots kill. Roughly weekly, less in winter.

Potting medium: Coarse bark chunks or basket culture - maximum air at the roots; never soil, never moss-packed.

Temperature & Humidity: 18-29°C days, cooler nights (5-8°C drop helps trigger bloom); 50%+ humidity appreciated.

Feeding: Weakly weekly balanced orchid feed in growth; flush pots monthly.

Rest & rebloom: Many rest after new pseudobulbs mature - water less until new roots/spikes show. Learn your plant's annual rhythm; the reward is the flush.

Propagation

Division at repotting: 3-4 pseudobulbs per division, each with a live 'eye'. Repot ONLY when new roots start - cattleyas resent ill-timed disturbance.

Common Problems & Pests

• No blooms = not enough light, always, basically
• Rot in dense wet media
• Scale insects hiding under pseudobulb sheaths
• Wrinkled bulbs = under-watering OR dead roots: check which

Toxicity & Safety

Orchids are non-toxic to cats and dogs - one of the safest flowering houseplant families.

Pros & Cons

FAQ

Why won't my cattleya rebloom?

Light, 95% of the time - move it to where leaves turn light yellow-green with gentle sun. The plant should look slightly 'stressed' by houseplant standards to flower.

When do I repot?

Only when new roots emerge (usually after bloom) - potting at the wrong phase sets them back a year. Coarse bark, snug pot.
