The Best Time to Water Grass for a Greener Lawn, and Less Water Waste

A well-maintained lawn is a source of pride for many homeowners, and one of the essential aspects of lawn care is proper watering. However, watering your lawn efficiently requires more than just turning on the sprinklers.

The Best Time to Water Grass

It involves understanding the best time to water, as well as the most effective methods to promote a greener lawn while minimizing water waste. In this article, we will explore the optimal time to water your grass, the periods when watering should be avoided, and the best practices for watering your lawn.

When You Shouldn’t Water Your Lawn

Watering your lawn at the wrong time can be counterproductive and wasteful. Here are a few instances when you should refrain from watering your lawn:

  1. Midday: Avoid watering your lawn during the hottest part of the day, typically between 10 a.m. and 4 p.m. During this time, the intense heat causes rapid evaporation, meaning much of the water will simply be lost to the air instead of nourishing your grass.
  2. Windy conditions: Watering your lawn on windy days can lead to uneven water distribution. The wind can blow the water off-target, leaving some areas oversaturated while others remain parched. It’s best to wait for calmer weather to ensure the water reaches its intended destination.
  3. Rainy days: It may seem obvious, but it’s important to mention that watering your lawn during or right after rainfall is unnecessary. Take advantage of nature’s irrigation system and allow the rainwater to do its job before resuming your watering routine.

The Best Way to Water Your Lawn

Now that we’ve covered when you shouldn’t water your lawn, let’s focus on the most effective methods to ensure your grass receives the proper hydration it needs.

  1. Early morning is key: The best time to water your lawn is in the early morning, preferably before 10 a.m. Watering during this time allows the grass blades to dry before evening, reducing the risk of fungal diseases. It also takes advantage of the cooler temperatures and calmer winds, resulting in less water loss due to evaporation and drift.
  2. Deep and infrequent watering: Instead of frequent shallow watering, it’s better to water your lawn deeply but less frequently. This encourages the grass roots to grow deeper, making them more resilient to drought and promoting a healthier lawn overall. Aim for around one inch of water per week, including rainfall.
  3. Use proper irrigation techniques: There are various irrigation methods to choose from, such as sprinklers, soaker hoses, or drip irrigation. Sprinklers are popular for large areas, but they can be inefficient due to evaporation and wind drift. Soaker hoses and drip irrigation systems provide a more targeted approach, delivering water directly to the roots with minimal waste.

In addition to these practices, consider monitoring the moisture levels of your lawn. You can do this by sticking a screwdriver or a soil moisture meter into the ground. If it slides in easily, the soil is adequately moist. If not, it’s time to water.

By following these guidelines and adapting your watering routine to suit your specific lawn and climate conditions, you can achieve a greener, healthier lawn while conserving water.


the best time to water your grass for a greener lawn and to minimize water waste is early in the morning, before 10 a.m. Avoid watering during midday when evaporation rates are high, and refrain from watering on windy or rainy days. Remember to water deeply but infrequently, and choose the most suitable irrigation method for your lawn. By implementing these practices, you can maintain a lush and vibrant lawn while being mindful of water conservation.
