Proper lawn irrigation is critical to having a healthy and attractive lawn. No matter who treats your lawn, or what products are used, without an effective and consistent watering program, your lawn will not look good. Every yard is different, but here are a few basic guidelines to follow:
What time of the day should you water? 

Water your lawn between the hours of 3 AM and 7 AM to prevent unnecessary evaporation and lower the chances of lawn diseases and fungal outbreaks. Avoid watering in the afternoon or evenings, as this is a surefire way to develop disease and fungal issues. Stick to the designated early morning hours for watering to keep your lawn healthy and thriving.

How much water does your lawn need?

Your lawn needs between 1” and 2” of water during the growing season. In extremely hot weather, you might need to increase the watering, but if your area experiences frequent rainfall, consider turning off the irrigation system. Remember, too much water can be just as harmful as insufficient water. Finding the right balance is essential for a healthy lawn. 


  • March - May = .5” - 1” of water per week. 

  • June - August = 1” - 2” of water per week. 

  • October - First Frost = .75” - 1.5” of water per week.

How often do you need to water?

Please avoid watering your lawn every day. Instead, opt for watering every 2-3 days, as this helps mimic natural rainfall. Deep and infrequent watering proves to be much more advantageous for your lawn’s health, as it allows the water to penetrate the plant’s root system effectively. It might sound amusing, but watering your lawn can be considered an art. By monitoring the weather forecast, you can adjust your watering schedule accordingly. For instance, you can apply more water before a heatwave to protect your lawn or conserve water if rain is predicted in the near future.

How can you determine the amount of water being applied to your lawn?

The simple answer is to use sprinkler measuring devices. These small measuring cups can be strategically placed around your yard, enabling you to calculate the water volume applied within a specific time frame. For best results, we recommend placing 2-3 of these devices in your watering zone for 15 minutes. Afterward, check the accumulated water in the cups. This approach will provide you with a much clearer understanding of how frequently and for how long you should run your irrigation system.
