Light
Cattleya orchids are considered high light orchids, requiring some direct sunlight in the mornings or evenings when grown indoors. When grown outside, bright, indirect light may be sufficient. The more light you can give your Cattleya orchid without damaging it (burning it or bleaching out the leaves) The better it will grow and bloom for you.
Water
Cattleyas like to dry out a bit between watering. How often you water is dependent on how quickly the potting mix dries out. Terracotta or un-glazed clay pots will dry out much faster than plastic or glazed ceramic pots.
When you water, completely drench the roots and allow the pot to drain. Never allow your plant to set in water for more than an hour. If in doubt, don't water! Cattleyas store water in their stems for times of drought.
Fertilizers and Supplements
Cattleyas do not require a lot of fertilizer. We recommend a well balanced fertilizer once a month at half or quarter strength the manufacturers recommended concentration.
Potting
Cattleya orchids like a very 'open' mix where their roots have good air movement and will dry out quickly. We use a medium size bark mix which includes hard wood chips, coconut husk chips, and sponge rock. The sponge rock provides open air pockets in the mix and can be substituted with anything from charcoal, to styrofoam peanuts.
