● Remember to adjust your watering minutes based on rainfall, types of grass and plants, and on sunny or shady locations.
NOTE: IN SANDY SOIL, WATERING IS MORE EFFECTIVE IF TURF IS WATERED TWICE, ON EACH OF THE ALLOWED THREE DAYS, AT HALF THE TIME SHOWN ABOVE.
NOTE: IF TURF STAYS HEALTHY, TRY REDUCING TIME BY 1-2 MINUTES PER ZONE PER DAY.
Please adjust your minutes to suit your landscaping situation:
Most lawns will not require three days of water a week; the allowed three days give you flexibility in designing your water schedule. To best manage your watering, you will want to avoid both using more water than your lawn needs, and using less. Many factors influence how much water to apply and how it’s applied: soil type, organic material, sun vs. shade, slope. For example, sandy soil needs frequent, short waterings; soils with lots of clay must be watered slowly and infrequently. Sunny areas dry out quickly; slopes lose more runoff. Xeric plants require less water than bluegrass. Visit www.denverwater.org for detailed information on managing your irrigation.
