Follow the weekly lawn watering guide and find out how many times per week you should water according to conditions for your county. The guide takes extensive data and simplifies it into how many days per week to water in each county. (Microclimates may require adjustments to your watering schedule.)
Install a water-saving smart irrigation controller and qualify for a money-saving rebate. Smart irrigation controllers take the guesswork out of how often and how long to water. These devices connect to WiFi and access weather data and adjust the watering schedule to account for rain, temperature, humidity, UV index and even evapotranspiration.
Don’t water when it’s windy or raining.
Don’t water between 10 a.m.- 6 p.m. (Or 8 a.m.-8 p.m. in Southern Utah.) The one and ONLY exception to this rule: If it’s windy every night, pick a time that’s less windy (even if it’s during the day). You could save more water by watering during the day because the loss to wind can be more than evaporation so make adjustments as needed.
Prioritize your watering to water the most valuable plants in your landscape first: Trees, shrubs, perennials, annuals then grass. Grass is the toughest and will enter dormancy during times of drought and high temperatures and recover when conditions improve.
Mow your lawn higher. Set blades to 3-4 inches. Taller grass means deeper roots that can access water that is deeper in the soil. Tall grass also shades roots and soil to reduce evaporation loss.
Place a rain gauge in your backyard to monitor rainfall and irrigation.
Remember that not all brown spots in your lawn are caused by a lack of water. If you have distinct irregularly shaped brown spots, the symptoms are most severe in late summer, and the section of dead turf can be pulled up easily, the problem is probably grubs, a beetle larva. They feed on your turf’s root system and kill it. If you question what is causing your turf problem, contact your USU Extension County Office or a local nursery professional. They will probably want to see a sample of your turf.
Water brown spots in your lawn with a hose instead of increasing the irrigation time on your timer.
Place children’s water toys on any dry spots on your lawn.
Apply as little fertilizer to your lawn as possible. Applying excess fertilizer increases water consumption and actually creates more mowing for you! Use iron-based fertilizers to simply “green up” your lawn instead.
Water your lawn only when it needs it. If you leave footprints on the grass, it is usually time to water.
