Light: Bright to Very bright
Cattleya percivaliana requires bright light conditions. They need nearly full sun to thrive and flower to their maximum. Remember, in habitat clear days are rare in summer, but clear weather occurs frequently in winter, when Cattleya percivaliana receives almost full sun. Air movement should be provided at all times to prevent sunburn and plants need protection from midday sun.
Temperature: 58˚F (14˚C) to 78˚F (26˚C)
In summer days, average around 74-78˚F (23-26˚C) and nights average around 58˚F (14˚C). In winter days, average 72-74˚F (22-23˚C) and nights average 54-56˚F (12-13˚C). Cattleya percivaliana can withstand low temperatures to around 41˚F (5˚C) for brief periods in winter.
Water: Let the medium dry between watering
Cattleya percivaliana should be watered frequently from spring through to autumn, but the roots must dry rapidly after watering. Water must be reduced when plants are actively blooming.
Humidity: 80% year round
Humidity is around 80% year round as rainfall is generally high year round in the climate where this orchid grows. Always provide constant air movement to prevent stagnant air, which could lead to pest infestations and fungal problems.
An easy orchid to care for recommended for beginners. These orchids are found in Venezuela and Colombia, where they grow on trees and rocks, in nearly full sun. They are usually found near rivers or streams at 1400–2000 m. Plants hold around 3–4 flowers per inflorescence, while the attractive, nicely shaped flowers, may be up to 12 cm across. They are often short lived and blossoms have a curious, somewhat musty odor which many find unpleasant.
When feeding this orchid, half the recommended amount of fertilizer should be used. Generally a balanced to high nitrogen fertilizer is used in spring to midsummer and a fertilizer higher in phosphates is used in late summer to autumn.
These orchids are generally grown is shallow pots, filled with a course, open medium with fast drainage. Undersized pots which allow 1-2 years growth should be used because the medium in larger pots remains wet too long after watering. This will therefore reduce the chance of root rot, as the medium will dry allot faster promoting healthy root growth.
