How Long to Water Your Lawn

How long to water your lawn is a question that many homeowners face. It can be tough to determine how long to water your lawn. You don’t want to underwater it, but you also don’t want to overwater it. The answer, of course, depends on a variety of factors, including the type of grass you have, the time of year, and the weather conditions. In this guide, we will discuss how long to water your lawn and provide some tips on how to achieve healthy and beautiful turf.

What to consider?

How long you water depends on a few things. If you have sandy soil, you need to water more frequently, but for less time, than if you have loam or clay-rich soil. This is because sandy soil can’t hold on to moisture and nutrients as well as clay and loam, so during hot and dry weather, it needs more watering, but they need to be shorter so that the soil doesn’t dry out too quickly.

It sounds obvious, but how much sun your lawn gets also determines how often and how much it needs to be watered. A lawn in the full sun needs more water than a lawn in partial shade.

How much rain you get also plays a role in determining how long to water your lawn. If there’s been a good rainfall recently, you don’t need water as often or as long as it’s been dry for a while.

Different varieties of grass have different watering requirements. Kentucky bluegrass, Bermuda grass, ryegrass and St. Augustine grass are some common varieties that require different amounts of water and thrive in different climates. Your local garden center should be able to tell you about the best types for your area.

How long do you water your lawn?

To get an idea of how long to water your lawn, check the moisture level in your soil before and after you water. The best time to do this is in the morning, before the heat of the day sets in. Use a garden trowel or soil probe to check the moisture level at different depths in your lawn.

A good rule of thumb is this: water long enough and deep enough to soak the soil 3 to 4 times. This will encourage deeper roots and make your lawn more tolerant of heat and drought.

If you’re not sure how long to water your lawn, it’s better to err on the side of too little than too much. Overwatering your lawn can do more harm than good, so start with shorter watering times and increase as needed.

When you’re figuring out how long to water your lawn, keep in mind that overwatering can create a lush, green yard that’s susceptible to disease. And under watering makes the grass more vulnerable to stress from heat, drought and pests.

Watering in the early morning is best because it gives the grass time to dry off before nightfall, which reduces the risk of fungal diseases. It’s also a good idea to avoid watering in the heat of the day, as this can cause evaporation and wastewater.

When you begin to notice the color of your lawn start to fade from green to blue-green or a bluish-gray, it means the grass plants are beginning to suffer from moisture stress.

At this point, increase your watering time by 15 minutes every other day until you notice the color improving and the turf taking on a healthy green appearance.

What not to do when watering?

  1. Don’t water your lawn every day. This can actually do more harm than good, as it encourages shallow root growth and makes your grass more susceptible to drought and disease.
  2. Avoid using a sprinkler system that sprays water onto your lawn’s leaves. This can cause fungus and other diseases. Instead, use an irrigation system that delivers water directly to the roots of your grass.
  3. Don’t water your lawn for more than an hour at a time. This will help prevent runoff and soil erosion.


Final thoughts

Watering your lawn is an important part of keeping it healthy and looking good. How long you water your lawn depends on a variety of factors, but following these tips will help you achieve beautiful turf that’s resistant to disease and pests.
