Ways to Water: Efficient Overhead Irrigation

Efficient Watering

Efficient watering wets only the root zone and does not allow water to run off. If you are seeing water running off from your landscape, you are watering too much.

Always water on an “as needed” basis. Too much water (overwatering) can cause root rot, weed growth, pests, and diseases, and many other problems in your lawn or garden.

  • Note: Too frequent waterings can promote shallow root systems, which lead to vulnerable turf and garden plants.

Learn how to calibrate your sprinkler system.

Amount v Frequency

The amount of water should never change, but the frequency should change as the seasons change.

  • Meaning: if your plants need more water, DO NOT add more water.

Turf

Turf needs more water during its growing season, typically mid-March to mid- October, so aim to water 3/4 of an inch per watering.

  • Meaning: set your system to deliver that amount of water each time!

If your turf needs more water than that, up the frequency of waterings, not the amount of water per application, as the watering restrictions will allow.

When to Water

So, when do you water? Check the soil, is it dry? If so, it is recommended to water the landscape 3/4 of an inch per event.

  • The best time to water is in the early morning before the sun rises, if possible. Less water is lost to evaporation due to the temperature, sun, and wind. If you water during the day, you’re likely to lose 40%-60% of water (and money) due to evaporation.

Remember, the amount of water per event should remain the same, only the frequency of waterings should change. For more information, read this publication.

Watering Restrictions

Always keep an eye out for watering restrictions from the Water Management District, click here for more information, or your local city or County ordinances, which might be more restrictive than what the Water Management District dictates.
