how much water for christmas cactus

Christmas cactuses should be watered regularly during the growing season, which is typically from spring to autumn. Water them thoroughly until the soil is completely saturated, and then allow the soil to dry out slightly between watering sessions. During the winter months when the plant is dormant, you should reduce the frequency of watering to prevent the roots from rotting. It's best to water the plant only when the soil is dry to the touch.
