Cattleya trianaei is as easy to cultivate as most cattleya hybrids and it will grow well in any medium you use for them. If you start C. trianaei growing early in the spring, right after it finishes blooming, it will complete its first growth by early summer, and rush into a second growth that will be completed in late summer. Be certain not to dry the plant off after the first growth is completed, however, or it may not start the second growth. Both growths should produce flowers in late December through February, after its autumn rest. If you want to produce the best flowers, avoid repotting the plant as long as possible, and only repot when new roots emerge from the lead pseudobulb. Like other Cattleya species, C. trianaei should have lots of sun and air and the leaves should be a light green color. Do not let the leaves get warm to the touch, however, because this is too much sun and may burn the leaves. Always keep C. trianaei slightly dry during its rest period to avoid rotting the roots, and start the plant growing right after flowering with frequent light sprays of water on sunny days.
