My preferred method for watering orchids is to gently submerge the grower pot In a pail of lukewarm tap water for several seconds, covering the soil and roots, but not the leaves. Remove the plant, allowing all the water to drain completely from the pot. I've had many questions regarding the Ice cube method of watering. I hand water to ensure the plant is completely irrigated. Melted ice cubes can leave dry pockets that stress the root system.
