Provide support staking as plant grows taller. Fertilize bi-weekly with diluted orchid fertilizer (higher nitrogen). Maintain warmth (65-75°F daytime, 55-65°F night).
Bud Formation

Reduce nitrogen fertilizer; switch to higher phosphorus formula. Maintain consistent watering and humidity. Provide cooler nighttime temperatures (10-15°F drop) to encourage blooming.
Flowering
6-10 weeksLarge, elegant orchid flowers open with pink, purple, or white petals and prominent yellow centers; flowers typically fragrant
Maintain humid conditions and consistent moisture. Avoid moving plant. Support flower stems if needed. Flowers typically last 1-3 days each, with successive buds opening over several weeks.

Fun Facts
- 🌱 Sobralia decora flowers typically last only 1-3 days, but successive buds on a plant can create continuous blooms over several weeks—a characteristic known as 'sequential blooming.'
- 🌱 The name 'Sobralia' honors Vicente Sobral, an 18th-century Spanish apothecary, while 'decora' means 'ornamental' or 'beautiful' in Latin, reflecting the plant's showy nature.
- 🌱 Unlike many epiphytic orchids, Sobralia species are terrestrial, naturally growing in moist forest floors and streambanks, which is why they require consistently moist (not dry) conditions compared to typical orchid care.
