How often should I water my yard??? This is a frequently asked question, with an answer that changes as quickly as our Texas weather! David recommends an app called WaterMyYard.org. This program, sponsored by Texas A&M Agrilife Extension, is a great tool to take the guess work out of watering your lawn. Sprinklers are not a "set-it-and-forget-it" type of device. Careful management will save water and money, as well as prevent disease in the turf and landscape. Rely on local weather data and weekly watering tips from a reliable source.
