However, make sure that the pot is elevated above the water level in the saucer. You should water Cattleyas when the potting mix feels dry almost to the bottom of the pot. This situation generally occurs every week or so from the previous watering. If in doubt, don't water. Wait another day or two.
Small plants can dry out quicker than large ones.
Plants should never stand in water. Cattleyas are generally large and fragrant flowers. The average flowering period for a Cattleya is 3 to 6 weeks depending on the environment. Make sure to water more often when Cattleyas are about to bloom, and throughout the blooming period. Once done blooming, Cattleyas will drop their flowers.
