Corsage Orchid (Cattleya) – Care Guide for Fragrant, Showy Blooms

Corsage Orchid (Cattleya)

Native to Central and South America, this attractive species prefers warm temperatures and medium light. Best kept on a windowsill (south, east, or west).

Flowering

Largest flowers up to 5 inches across, in all colors, with strong fragrance. Typically blooms once a year; flowers last 2–3 weeks (some hybrids 5–6 weeks). Requires filtered direct sun and cool evenings (55°F) to initiate flowering.

Foliage

Long leaves attached to large pseudobulbs connected by a horizontal rhizome. Pseudobulbs store water and energy. A bloom sheath emerges where pseudobulb meets leaf—flowers appear there. When pseudobulb matures, its outer layer (sarong) turns brown/white; peel it off to prevent bugs. Old pseudobulbs brown and shrink after a few seasons; remove at next repotting.

Displaying and Growing

Beautiful in clay pots (best for watering), bright rooms, windowsills. Display different colors together.

Cattleya Care Instructions

• Temperature: 55°F night to 90°F day. Can go outdoors in summer. Evening temperature drop required.
• Light: No direct sun (damages leaves). Medium/filtered light; south/east/west room. Morning direct sun okay, not afternoon summer sun. Artificial lighting works for pros.
• Watering: Let dry between waterings. Established: 7–10 days; young: 5–7 days. Best method: soak pot in water 10–15 min (clay pots). For plastic pots, place in empty bowl, slowly add water, soak 10–15 min. Or run tepid water in sink for 1 min.
• Soil: Soilless mixes: bark, rocks, perlite (roots need air). Epiphytes in nature—cling to trees/rocks. Wet soil kills them.
• Fertilizer: Balanced orchid fertilizer weekly.
• Humidity: 40–70%. Pot on pebbles in water tray for evaporation humidity.
• Propagation: Spring after blooming. Divide plant; each division needs ≥3 shoots.
• Pruning: After flowers die, cut spike at base of pseudobulb.

Potential Problems

• Light: Too little → no bloom, old bulbs die, new ones weaken. Too much → leaf burn. Mimic natural habitat.
• Overwatering: Causes root rot.
• Pests: Scale and mealybugs common. Treat with Pest Oil.
