Tips to reduce water use on lawns and yards

Lawns, yards and other landscapes account for about half of domestic water use. Here are some tips on ways to conserve water applied to landscapes.
– Harden or toughen lawns by watering less frequently but deeply. This encourages deeper root growth, which makes lawns more drought resistant. For more information, contact your local Cooperative Extension office or visit http://www.ext.colostate.edu/PUBS/GARDEN/07202.html.
– Do not apply all the water the landscape needs during a short period of time. Water applied too quickly may run off the land and be lost in ditches or gutter systems.
– Use a soil probe or shovel to determine a lawn’s average root depth. Water the lawn until the soil is moist to that level.
– Water lawns overnight between 10 p.m. and 8 a.m. when conditions are less windy, cooler and more humid. Evening watering helps reduce the amount of water lost to evaporation.

– Make sure that sprinkler systems are working properly. Don’t water sidewalks, streets or parking lots. Proper sprinkler system maintenance is a must.
– Mulch flowerbeds and gardens. Mulch conserves water because less moisture is lost to evaporation and promotes healthier plants.
– Leave a little more length on lawns when mowing them this summer. Longer grass blades shade the soil and reduce water loss.
– Use lawn sprinklers that deliver large droplets of water instead of a fine mist, which is more easily lost to evaporation.
