Over watering a plant does significant damage to the health of the plant and is a common way that beginners unintentionally kill plants. The amount of water required by a plant and how often it is needed varies depending on the species and environment of the plant.
Some plants require a dry period between waterings. Research specific plants to determine the proper amount of water for each of them, and avoid under watering and over watering. Consider an irrigation drip system or other automated watering system using timers. Soil that has become too dry allows the roots to break loose and leads to the plant becoming unstable. Soil that is over saturated with water drowns the roots without proper drainage.
