Although it may seem simple enough, knowing how to water your lawn the right way can make all the difference in maintaining a healthy lawn.

1. Know what type of soil you have

Generally, the frequency and amount of water you apply to grass will vary depending on the soil, type of grass, and weather conditions. It is therefore ideal to know what type of soil you are dealing with. If you have sandy soil, it will absorb water quickly and require frequent watering. On the other hand, if your soil is clay-based, it absorbs water slowly, retaining water much longer, so it doesn’t require as much watering.

2. Water at the right time

Although you may be tempted to water your dry lawn as much as possible, it should be done at the right time. Experts advise that the best time to water your lawn is early morning or late evening when it’s cooler. If you water during the hottest parts of the day, most of the water will evaporate and not be absorbed by the lawn. “Avoid the urge to water if it’s wet,” advises Craig Elworthy, founder of Lawnbright. “You may think giving your lawn some water will help – but your lawn is actually fine. When it’s dry, there’s an imbalance in the water between your lawn and the air, but in humid air there is no imbalance and the water in the soil is retained, so don’t water unless your lawn needs it.

3. Soak the lawn with a sprinkler system

Be sure to soak the lawn thoroughly until you see small puddles of water on the surface. “The best way to water your lawn in hot weather is to use a sprinkler system and really soak the lawn,” agrees gardener Jonathan McQuire. “It takes a lot of water to keep grass healthy in the heat, and you’re sometimes better off using water from your flower beds, as the flowers are less hardy and often more expensive. Even if your grass looks like straw, it will recover.There are many affordable sprinkler systems like this GOLDFLOWER garden sprinkler ($14, Amazon (opens in a new tab)) to best water your lawn.

4. Avoid water runoff

If you apply more water than the lawn can absorb, the excess will flow into the gutters or elsewhere. To avoid wasting water, which is especially important if you are in a drought-stricken area, it is advisable to water in short intervals of around 10 to 15 minutes. Turn off the water or move the sprinkler to allow water to properly penetrate the lawn before turning it back on for another 15 minutes.

5. Leave your grass long

Despite the desire to mow your lawn for these summer gatherings, leave your lawn for a long time during heat waves. “One way to keep your lawn healthy is to anticipate warmer weather and avoid mowing your lawn too short. Longer grass is tougher and more likely to survive the heat,” says McGuire. You can also leave some of the grass clippings on top of the lawn to form a fine mulch that will protect the roots and help retain moisture.However, make sure the grass is not totally covered, because it can kill it.” Long grass also establishes deeper roots for a healthy lawn.

How often should I water my lawn during a heat wave?

Experts recommend watering twice a day under drought conditions. However, it is always best to monitor your lawn and make any necessary adjustments, as no lawn is the same. “Check for signs of heat stress. The grass will take on a silver hue before it browns and goes dormant,” suggests Elworthy, “if you see a silver hue on your lawn, be sure to hit it with water, because she is under heat stress and will soon fall asleep.” Also, if the lawn doesn’t seem to dry out quickly between waterings, you can lengthen the intervals between waterings.

If you live in an area with water restrictions or have a high water bill, you may not be able or willing to water your lawn as often. In this case, it is better to replace the grass with drought-resistant plants. Be sure to check out our other water saving tips to learn how to use less water and lower your bill.

How much water should I use?

Try not to overwater your lawn, as this can promote weed growth and the risk of mold and disease. “Make sure you get between 1 and 1.5 inches of water on the lawn each week,” advises Elworthy. “A simple rain gauge is all you need. Some even use a coffee mug and a ruler. It doesn’t need to be too accurate.” Another way to check this is to probe the ground with a stiff metal rod. The stem should move easily through moist soil, then stop once it reaches dry soil.
