Cattleya dormaniana should be watered regularly throughout the year, but they must dry rapidly after watering. Make sure that the plants never stay dry for long periods of time, however. Give mounted plants a daily misting in summer with a thorough soaking of the entire plant and slab twice a week in summer, or three times a week in extremely hot weather (adjust for your climate). Water should be reduced somewhat in winter, but plants should never stay dry for long periods. Grow Cattleya dormaniana in an open fast draining medium such as coarse bark nuggets. It can also been grown mounted on cork. When mounting, do not use sphagnum moss between the mount and the plant because it retains too much moisture and promotes rot. Divide, repot, or remount only when new root growth is just starting. This lets the plant become established in the shortest possible time with the greatest success. Easy to grow.
