Pot the cattleya orchid in a soil medium that drains quickly. Remember, these are air plants so you need a medium that allows the roots to dry out and get air between watering times. For good cattleya orchid care, don't let the roots stay wet too long.
Water the cattleya regularly, but let the roots dry out between watering.
Provide humidity for a cattleya orchid. These plants originated in rain forests, so adequate humidity is important to proper cattleya orchid care. Keep the relative humidity between 50 and 80 percent. Misting as part of the orchid care helps with humidity.
Allow the orchid to get plenty of bright light, but shield it from intense light. Midday and summer sun can be too intense for a cattleya orchid.
Feed a cattleya orchid regularly to provide it with consistent orchid care. Fertilize every other week during the growth season and cut back to once a month when the plant stops blooming.
