Light

Cattleya plants need a good amount of light to grow and flower well. A good guide to whether or not a plant is getting the proper light is the colour of the leaves. They should be a medium green, rather than a dark lush green. The pseudobulbs should be straight and upright, without needing support. Micro-mini and Mini types typically require less light, and can be grown very well under fluorescent lights, an average east or west window or filtered south window. Compact and standard catts may require more light to bloom, especially if they are unifoliate. Unifoliate means that they never have more than one large leaf at the top of the pseudobulbs. Bifoliates (2 or more leaves at the top) have a lower light requirement. If you find that your larger cattleyas aren't blooming, then try a brighter east or west window, or less filtered south window. You might also verify that your fertilizer does not contain too much nitrogen, which could suppress blooming.

Temperature

The best temperature range for growth and flowering is 27 ° C during the day, and 16 ° C at night. However, these plants are very resilient and can tolerate a wider range of temperatures if the humidity and watering are adjusted. A good rule of thumb is to increase humidity and watering at higher temperatures, and reduce both of them at lower temperatures. Lower temperatures will give brighter and more uniform coloration of the orange and red mini-catts, because of the Sophronitis in their backgrounds. At higher temperatures, especially night temperatures, your red cattleya could produce blooms that are more orange in coloration.

Watering and Humidity

Cattleya plants have evolved water storage organs to withstand periodic drying in their native habitats. For this reason, it is recommended that plants in cultivation be allowed to go nearly dry between waterings. Mature plants generally need to be watered about once per week, smaller plants perhaps every 4-5 days during most of the year. At cooler times of the year, plants may be left a little longer between waterings. When in doubt, wait a day to water. Always water thoroughly, allowing water to drain well through the drainage holes in the bottom of the pot.
