How often should low maintenance houseplants be watered? The https://gardyna.net/atering needs of low maintenance houseplants vary depending on the plant species, season, temperature, and humidity levels. In general, most low maintenance plants should be watered only when the top inch of soil feels dry to the touch. Plants such as Snake Plant and ZZ Plant may need water only once every two to three weeks, while others like Peace Lily may require slightly more frequent watering. Over watering is one of the most common mistakes in indoor gardening and can cause root rot, yellow leaves, and poor plant health. It is always better to check the soil before watering rather than following a strict schedule
