Today’s irrigation systems include sophisticated controllers that allow you to easily adjust watering schedules to fit different needs. Here’s your guide to staying water-wise with your lawn all season long.

How can I save water when watering my lawn?

Be sure to set your sprinklers to water plants, not your driveway, sidewalk, patio or buildings. Keep in mind that different zones will almost always need different watering schedules, so be sure to schedule each individual zone in your irrigation system to account for:

  • The type of sprinkler used
  • Sun or shade exposure
  • Soil in that section

What happens if I water my lawn too much?

The type of soil you have will determine how quickly water can be absorbed without runoff. Exceeding that limit will cause runoff and water waste. Watering too much and too frequently can also result in shallow roots, weed growth, disease, and fungus, so try to only water when it’s needed. 

When is the best time to water my lawn?

To prevent water loss, water your lawn when the sun is low or down, winds are calm and temperatures are cool — typically between the evening and early morning. Watering during the heat of the day may cause losses of up to 30 percent due to evaporation.

What is the most efficient way to water my lawn? 

Water more often for shorter periods. For example, setting your system to run for three, 5-minute intervals lets the soil absorb more water than watering for 15 minutes at one time, reducing runoff.

Always adapt your 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.

What is a Smart Controller and why do I need it?

A smart controller, like Toro’s EVOLUTION series irrigation controller, allows for unprecedented control and ease-of-use when managing your irrigation system and water usage.

When paired with a Smart Connect® wireless weather sensor and the associated wireless accessories, the Toro EVOLUTION controller helps you better manage your water usage by using live temperature and solar measurements as well as historical weather data for a particular location to calculate the right amount of water needed from the irrigation system.
