Today’s irrigation systems include sophisticated controllers that allow you to easily adjust
watering schedules to fit different needs.
• Get in the zone. Schedule each individual zone in your irrigation system to account for type
of sprinkler, sun or shade exposure, and soil in that section. Different zones will almost
always need different watering schedules.
• Consider soil type. Type of soil determines how quickly water can be absorbed without
runoff. Watering more than soil can absorb causes runoff and waste.
• Don’t send water down the drain. Set sprinklers to water plants, not your driveway,
sidewalk, patio or buildings.
• Water only when needed. Saturate root zones and let the soil dry. Watering too much and
too frequently results in shallow roots, weed growth, disease and fungus.
• Water at the best time. Watering during the heat of the day may cause losses of up to 30
percent due to evaporation. Prevent water loss by watering when the sun is low or down,
winds are calm and temperatures are cool — typically between the evening and early
morning.
• Water more often for shorter periods. For example, setting your system to run for three,
5-minute intervals lets soil absorb more water than watering for 15 minutes at one time,
reducing runoff.
• Adapt watering to the season. Familiarize yourself with the settings on your irrigation
controller and adjust the watering schedule regularly based on seasonal weather conditions.
Or invest in a smart controller so your system can make these changes automatically.
