Establishing a proper watering schedule is crucial for the health of your built-in indoor cactus garden. Cacti are desert plants and have adapted to survive in arid conditions. They store water in their fleshy stems and do not require frequent watering. Allow the soil to dry out completely between waterings, and then water thoroughly until it drains out of the bottom of the pot. During the winter months, reduce watering frequency to prevent overhydration.
