Yard care and water savings tips
If you wash dishes by hand, fill one half of the sink with soapy water and the other with clean water instead of letting the water run.
Cut irrigation to two to three days per week.
Add 2” to 3” of mulch around trees, plants and gardens to reduce evaporation and control water-stealing weeds.
Look for sprinklers that produce droplets, not mist, or use soaker hoses or trickle irrigation for trees and shrubs.
