Watering Lawn & Summer: 9 Tips to Keep Your Grass Green Now!


You need to water your lawn enough in the Summer to keep it alive and thriving but if you apply too much you can quickly ruin your lawn. I show you the best tips to water your lawn you will have a great lawn during these insanely hot Summers.

1. What is the Best time of day to water (new or established lawns)?


In Hot weather, it is best to water your lawn in the early morning before the hot sun dries it out. For the best results try watering before 8 AM if your lawn gets full sun early in the morning.

If you have a tree in your yard then you may be able to stretch it out to 10 AM if a fair portion of your lawn is shaded.

This gives the water a chance to soak into the soil to a depth of 8+ inches.

Keep in mind: If you have sandy soil then water will more easily reach the 8″ deapth than it would with clay soil loam.

With Mild temperatures, you should water in the morning but can also water later in the day.


2. What is Best Way to water your lawn?


Water 2 times per week. Don’t water every day because your grass’s roots will be shallow since they won’t have to grow deep to get water.

Give them a good soaking 2 times per week and you will have a strong and green lawn throughout the entire year.


A. Go with pulsating sprinklers. Pulsating sprinklers hooked up to a garden hose are a great option for homeowners who do not have an existing sprinkler system installed in their lawn. You will have greater directional control than if you used rainbow sprinklers that go up and down.

  • They often water your roof, trees and other objects that you are not trying to waste water on.

B. Set up the sprinkler. Turn it on.

C. Set up a rain gauge 20 feet out from the sprinkler to catch water. You can use a pan or square container. Don’t use a round bowl as you want to have as accurate a collection of water as possible.

  • Time how long it take the sprinkler to fill up the pan with 1/2” of water. Make sure your sprinkler heads are clean and water is being evenly applied to your lawn (for that zone).

Lawn getting rain? Let your soil dry out…you read that right. Your soil needs to dry out so the grassroots will have to grow deeper. If you watered 2 consecutive days then the soil would not dry out enough.

No Rain? During a hot, dry spell with no rain – go for 3 waterings / week with 1/2″ for each time.


D. Get a sprinkler timer and enter the time in so you know when to move the sprinkler to the other end of the yard.

E. No timer? Set up the rain gauge and test your sprinkler so you know if it will take 30 or 35 or 45 minutes to get that 1/2″ of water. You can set your alarm and then move the sprinkler once it goes off.

3. Growing grass from seeds?
Water is critical to the success of grass but essential for new grass to develop and thrive

  • New grass will begin to sprout within 6 8 days after you apply it. Make sure to keep the soil moist for at least 2 weeks.
  • Don’t oversoak the grass.
  • It should have proper drainage.
  • You want to make sure it is damp at all times.
  • After the grass germinates lower the amount of water you apply but still apply it daily so the grass will establish deep roots.

4. Is it better to water your lawn in the morning or at night?

It is better to water your lawn in the morning. It is usually cooler and will help your lawn prepare for a long, hot day. Lawns often get dew during the night so they get some water. If you don’t water in the morning then your grass will often go 24 hours without a drink. In the hot Summer, this can quickly lead to dry lawns if they are not adequately watered.

5. Should I water my lawn during a heatwave?

Yes. You need to water 3 times per week up to 1/2″ of water for your lawn. The hotter the Summer gets the more you will have to be aware of the extreme heat your lawn is experiencing.

A Summer heatwave doesn’t mean that you don’t have to water your lawn. You just have to water a smart time (early morning or late evening).

Morning is best but you may want to water when you water your plants for convenience sake.

6. What does an overwatered lawn look like?

An overwatered lawn is – wilted and does not stand up straight. Also, if you consistently overwater your lawn it will not have very deep roots.

If you then stop watering it for some reason it will quickly fade from light green to a grey-brown color.

It is best to be consistent with the amount of water your application on your lawn and how often you water it.

Your goal is for your grass to have deep, healthy roots that can take a heatwave as well as disease which may come afterward.

7. Should you mow lawn in extreme heat?

Ideally, you should mow twice per week – in the morning when it is not too hot outside. Don’t mow in the middle of the day when there is extreme heat. This will help to keep your grass low enough that it will not grow too high. Extreme heat is bad for grass and causes it to slow its growth.

8. Can you water a lawn by hand?

Ha. Yes you can but it will take a long time and many cans of water. If you have a really small lawn this would be a possibility. Most lawns are at least 20′ x 30′ which requires a sprinkler or 40 cans of water.

9. How do you water your lawn efficiently?

1. Make sure your sprinkler is set up to water the area you intend on watering. 

2. Test it to make sure water is not getting on your driveway or is not spraying into your garden mulch or hitting your house. This will just waste water. If the water is not hitting your lawn you should change your sprinkler settings to a limited area. You can do this by narrowing the swivel of the end stopper.

3. Reposition the sprinkler so it only waters your lawn – or to a location where you won’t waste that much water and time.

4. Watch. Make sure to watch your sprinkler for a few minutes so you know that pattern and the overspray is not too much….so you don’t waste water. . 

5. Get a water timer. These little guys are great for limiting water and can save you a lot of money if you forget to change your sprinkler location. Life happens and we forget sometimes.
