Water use guidelines
For the week of May 24-May 30, precipitation was .48 inches and turf grass in the area used 1.009 inches of moisture, according to WSU AgWeathernet data. Home irrigators should run spray type systems 3 times for 7 minutes and rotor type systems 2 times at 40 minutes this week. Calculations are based on average precipitation rates, please adjust for local conditions.
Yard care and water savings tips
Practice smart watering for healthier plants and make every drop count. Some easy ways to lower water bills and get more water to plants include:
Build your soil with compost and mulch to hold water and prevent evaporation.
Choose low water use water plants. Once established they can often thrive just on rainfall.
Use soaker hoses or drip irrigation on beds — they save 50 percent or more water compared with sprinklers.
Use a timer that screws onto the faucet (available at garden stores) to water just the right amount.
Water lawns separately from other plantings. Ensure sprinklers are not watering the pavement, too.
When soil is dry or compacted it won’t absorb water quickly. If water puddles, stop watering a while and then restart, so the water has time to soak in.
Water in the early morning or evening — if you water at mid-day, half the water just evaporates.
