Sufficient lighting is a must for successful cultivation. Cattleyas prefer either an east or a lightly shaded south-facing window. West windows should be used with caution. Depending upon the location of the home, the west window may become very hot during the late spring through early fall. The foliage on the plants may burn.


Cattleyas adapt to a wide range of temperatures. Provide nighttime temperatures 55 to 60°F and daytime temperatures 70 to 90°F. Plants can tolerate temperatures of up to 100°F, if shading, humidity and air circulation are increased.


Depending upon the temperature, Cattleyas should be watered about once or twice a week. During the summer, the plants may need to be watered every 4-5 days. The rule of thumb for watering should be as followed : More heat more water, less heat less water.

Cattleyas may be allowed to dry out between waterings. Try to water the plants early in the day, so that the foliage will be dry by nightfall. To prevent bacterial and fungal disease use Physan 20 once a month.


Cattleyas prefer 40-60% humidity. Humidity Trays may be needed.


Cattleyas must be fertilized on a regular basis! For best results, use Norman~s Optimal Orchid Nutrients every other week. It is recommended to pre-water plants before applying the diluted nutrient solution if the potting media is dry.


Cattleyas should be grown in Medium Orchid Bark. The bark mix should be moderately coarse to allow for free drainage. Cattleyas should be repotted once every two years. Ideally, Cattleyas should be repotted in the spring.
