Best Time to Water Grass

What is the best time to water grass? The best time to water grass is in the morning before 10 am. In the early morning, winds tend to be calmer, so water can quickly soak into the soil and be absorbed by the grassroots before it can evaporate.

Best Time to Water Grass

Water is an essential part of healthy grass. It is essential, however, that you make sure you water it properly. If you use Sprinkler at night, for example, it sets the right conditions for disease. If you water lightly, the grassroots will not grow deep enough, which will put your grass in trouble during hot weather.

When to Water the Grass

If you find that your grass has taken grey concrete or appears dull green, it tells you that it needs water. You can also check your grass by walking on it: If your steps do not disappear quickly, the grass blades do not have the necessary moisture to spring back.

While it may seem like you can go out and water grass at any time during the day, your grass needs extra care. Morning watering is the best time for your grass; it is cold, and the winds are often calmer so that water can seep into the soil and absorb the roots of the grass before evaporation.

If you have to water in the evening, try between 4 to 6 pm, which should give the grass time to stop before evening. Over time, when you water, there is a greater chance of disease becoming more common in your grass.

However, it would be best to be careful that you do not have to water your grass. The grass is resilient. Well-established and well-maintained grasses can survive for weeks without water by dormant and then recover when the rain returns.


Try to water the grass in the early morning. and in the evening try to water between 4 pm-6 pm.

How Much Water to Use

When watering a grass, it is usually recommended to water up to 6 to 8 inches of wet soil. To soak the soil, most grasses need 1 to 1.5 inches of water per week, either rain or watering. That amount of water can be used during single watering or divided into two watering during the week. Just make sure you don’t overwater your grass.

How to Tell If You’ve Watered Enough in the grass

:small_blue_diamond: Check the Soil

To see how long it will take to immerse the soil, look at it every 15 minutes during your first watering using a screwdriver to check how deep the water has moved. Note the time when the soil has been soaked to a depth of at least 6 inches, which is why you will need to water your grasses each time next.

:small_blue_diamond: Do the Math

This is the easiest way to have a spray system because the flow rate (litres per minute) will be available from the manufacturer. Just multiply the square photograph of your grass by 0.62 gallons (equivalent to 1 inch of water per square foot), and divide by the spraying flow rate. This will tell you the number of minutes to use your spray system.

:small_blue_diamond: Measure with Cans

Place empty, clean tuna cans in different areas around the grass and estimate how long it takes to collect 1 to 1.5 gallons of water per hole. Since spray coverage patterns can vary across the grass, use the average time to fill all the tins.

:small_blue_diamond: Use a Flow Timer (or water timer)

Choose a timer that measures the flow of water in hundreds of gallons. Multiply the square images of your grass by 0.62 gallons (equal to an inch of water per square foot) to get the total number of gallons needed for all grass.

When watering your grass, you may begin to notice that your grass does not absorb water as quickly as it should. If you find that puddling occurs whenever you water, try watering in short cycles until the required time to enter the required amount of water. For example, 10 minutes on, 10 minutes off, 10 minutes on, etc.


You’ll know that you have watered enough in the grass if you can easily stick a screwdriver 6 to 8 inches into your soil.

Watering Different Types of Grasses

Do not rely solely on Mother Nature for watering during the first year of growing your grass, whether it is newly sown, sown, sprigged, or grafted grass. Additional water should be provided regularly.

When watering freshly planted grass, the important is to keep the top half of the soil moist but not soggy. You will need to treat the sown area once or twice a day. When the seeds begin to germinate, continue to keep the top two inches of soil until the new grass reaches a height of three inches. After that, start to reduce the amount of irrigation twice a week and immerse the soil to a depth, about 6 to 8 inches to encourage grassroots to grow deeper into the soil.

:small_blue_diamond: Warm Season Grasses

Warm-season grasses such as oysters and bermudagrass grow best when the air temperature is above 80 degrees. They decrease when daytime temperatures start to drop, but they still need moisture to stay healthy. Continue watering as long as the grass grows and needs regular mowing. Fall is not the time to plant grass for the warm season. Wait until spring, when the active growing season begins.

:small_blue_diamond: Cool Season Grasses

Cool-season grasses, such as bluegrass, fescue, and rye, thrive in autumn, recovering from summer dormancy. Cool temperatures keep evaporation levels low, but these grasses still need water and a half-inch of water every week until the frost stops growing season. Cool-season grass is usually ripe in the fall, and watering after composting is vital to wash the manure at grass levels down to the soil.


Cool-season grasses need water only every three weeks or so if there has been no rain. Warm-season grasses require regular watering to maintain a healthy root system during their midyear high-growth season.

Typical Mistakes When Watering Your Lawn

The idea of watering the grass may sound like a no-brainer, but in reality, there are many mistakes you can make along the way that can prevent the grass from looking good. Fortunately, there are some practical tips for watering grass that can help you become a watering expert.

:small_blue_diamond: An “Any-Sprinkler-Will-Do” Attitude

No grass is created equal, which is why Gilmour sprays are also different. Save water by sprinkling only where needed. It is essential to consider the size and shape of the grass. Then choose the best sprayer for the space.

First, get the grass footage with the Gilmour Lawn Size Calculator. Just connect your address, use the tool to measure the area to be irrigated, and decide from there whether spraying a small, medium, or ample space is required. Next, consider the condition of the grass. The sprayer should cover the shape and size of the yard.

For example, the Adjustable Pattern Master Circular Sprinkler suits round or irregular spaces with a custom spray pattern. Be a water spray designer; pull the anchors to reduce spray access or press down to increase the distance.

:small_blue_diamond: Ignoring Your Grass’ Needs

Taking the grass age into consideration, it is essential. Full-grown grass can handle more powerful spray, and freshly planted grasses need less contact. If you have a small area of freshly planted seeds, Stationary Square Sprinkler works best with small watering. At the same time, the Adjustable Length Wind-Resistant Rectangular Sprinkler can cover a large area.

To spray growing weeds and grass, try the Circular Sprinkler Spike with a switch on/ off switch. The diffuser pin allows for custom-sprayed power, from a constant shower of fresh grass to a more powerful stream on mature grass.

:small_blue_diamond: Watering at the Wrong Time

Timing is essential to water well. Between 6 am and 10 am, early morning watering during the day leads to wasteful evaporation. Night watering makes the drops cling to the grass all night, increasing the chances of grass diseases.

The Dual Outlet Electronic Water Timer will look helpful in those mornings when you are away or want to sleep. Just set the start time, frequency, and irrigation duration, and let the timer take care of the rest. The dual outlets make it easy to connect two pipes simultaneously and arrange different schedules for different parts of the yard.

:small_blue_diamond: Watering the Wrong Amount

Watering the wrong amount is a common mistake. It can be one of the most dangerous. Unless you irrigate newly planted grass seeds, do not water every day.

Regular, slow watering wastes water and money. It also leads to many grass problems, including disease, pest infestation, and heat and cold damage. On the other hand, long-term irrigation, often “deep watering,” produces deep roots that mean that grass can thrive in times of drought. A good irrigation program is once or twice a week, about 25 to 30 minutes each time.

Caring for the grass does not have to be tedious, time-consuming. Once all the tips and tricks are in your backpack, it will be easy to develop a plan that leads to a beautiful green lawn.


Typical mistakes when watering grass is: watering the lawn in the hot sun, Watering every day at the wrong time, using the wrong type of sprinkler, and watering the wrong amount.

Frequently Asked Questions

Following is mentioned some frequently asked questions related to “best time to Water Grass,”; which are answered briefly.

1. Is it better to water the lawn at night or morning?

Well-watered, time is everything. Early morning water, between 6 am and 10 am watering during the day, leads to wasting steam, while night watering makes the drops cling to the grass all night, increasing the chances of grass diseases.

2. How many times a week should you water your lawn?

You should water your lawn once or twice a week, giving your lawn 1 to 1.5 inches of water each time. The exact number of minutes for each irrigation will vary from grass to grass, depending on factors such as the size of your lawn, the type of spray you have, and its settings.

3. Should you water the grass every day when it’s hot?

For best results, water your grass three times a week if it is not raining. In hot, dry climates, water plants and flowers every day. The grass should be wet and more frequent than treating it lightly every day. Use a rain gauge to make measuring an inch of water more accessible.

4. Is 4 am a good time to water your lawn?

Wintel has more than ten years of experience in installing and maintaining spraying systems. He says four o’clock in the morning is a good time to water the grass. The soil can absorb most of the water at once. Wintel says that late afternoon and evening are still the worst time for irrigation, so get a timer.

5. Is it bad to water grass at night?

To water grass at night is a good condition for fungal growth. As well as cutting very short grass, watering at night is the worst thing you can do on the grass. As a general rule, you should rinse long enough to moisten the soil to about six inches, which is about the same depth as the root system of healthy grass.

6. Should you water grass after mowing?

No, you should not water grass after mowing. While it is perfect for irrigating after mowing the lawn, you should avoid watering before mowing. The wet grass will only clump up when you mow, clogging your mower and being a pain. That’s why you should not mow if it’s raining recently.

7. What does an overwatered lawn look like?

Dying patches of grass can also indicate problems with irrigation. Other symptoms include many weeds such as crabgrass and nutsedge, thatch, and fungal growth such as mushrooms. Runoff after watering is one of the signs, along with the yellowing grass.

8. How do you water grass in extreme heat?

Try to irrigate deeply and regularly. Deep watering means watering the entire root system. Irrigation often means watering only when the grass is dry. Try watering early in the morning when your lawn can get the full benefit of hydration before the sun sets during the day.

9. What does Epsom salt do to lawns?

Epsom salt is an organic compound full of beneficial minerals in the grass. The iron in Epsom salt, for example, helps the grass to grow stronger and healthy. In the meantime, Epsom magnesium salt measures the pH level of your grass so that it is less acidic.

10. Can you water the grass at 5 am?

The best time to water your lawn is from 4-6 in the morning. At that time, the heat of the day can evaporate your water by 30-50%. When it comes to the 4–6 am window, the sun’s position is also advantageous because it is not so low that the soil is cool and does not absorb moisture anymore.


Best time to water grass; watering the right amount, and watering at the right time will help your grass flourish. Watering 1 inch per week and at the correct times will keep your grass healthy and green. The next step is to apply fertilizer and mowing at all times.

Grass watering tips

:ballot_box_with_check: Irrigation during the day is a waste of your time and water because the sun is hot and rapid evaporation will automatically turn water into gas even before the soil absorbs it.

:ballot_box_with_check: Evening watering can have serious side effects. Lack of sunlight will leave wet grass all night, which is suitable for the ■■■■■■ to grow. You should also avoid watering when there is wind to reduce evaporation. Watering only when it is windy can waste your water. This will rinse your roadways instead of your grass.

:ballot_box_with_check: Deep watering your grass will help the roots stay apart and absorb more nutrients, moisture and oxygen. The rule you need to irrigate your grass deeply by providing at least one and a half inches of water per week (including rain) to irrigate the soil sufficiently, depending on the type of grass. Adequate moist grasses will improve deep root systems that help your grass grow and avoid the risk of drought, disease, weeds and other issues.

:ballot_box_with_check: To test, you water your grass enough, you can do a “screwdriver test”. Just take a screwdriver and press it into the ground; if it moves six to eight inches from the ground quickly, then water your grass enough.

Watering systems

Nowadays, we usually do everything we do by hand, and that works by watering your lawn. Homeowners have now invested in irrigation or underground spraying systems to keep their grass well.

:small_blue_diamond: Impact sprinkler

It is recommended that you use a pulsating spray if you have mature grass. The rotating head shoots water in drawing water with a powerful flow to produce a very heavy spray of water. It is not suitable for freshly planted grass as it can flood the seeds. However, it is better to use in large areas. When placed in a stagnant triangular pattern, it can accurately distribute water and has adjustable screws and oars that separate the jet stream and disperse the water.

impact sprinkler

:small_blue_diamond: Oscillating sprinkler

If you have new grass, you can use an oscillating sprinkle. This spray delivers water to a rectangular pattern and then stores more water near the spray head, allowing water to fall slightly into the grass with minimal impact on the seed.

You can compare different types of sprays and choose the one that best suits the size and shape of your grass. You can also install your sprinkler by checking online videos as a guide. You need to make sure you know all the gas lines, power lines and TV cable lines and check the current water restrictions in your local municipal area before you start digging. Make sure you call your service companies if you need help.

How Much Water Do You Use When You Water Your Lawn?

:small_blue_diamond: You should water your grass thoroughly two or three times a week.

:small_blue_diamond: Your lawn needs 1 - 1 ½ inches of water per week.

:small_blue_diamond: To measure the time it takes to get that amount of water, you can put an empty tuna, about 1 inch long, under your spray and see how long it will take to get half the water. This usually takes about 30 minutes.

:small_blue_diamond: Irrigation for 30 minutes, three times a week, means that your grass will get 1 ½ inch of water. You can also do 20 minutes, three times a week, to get 1 inch of water per week.

:small_blue_diamond: However, we recommend that you experiment to find the right time required depending on the type of irrigation system you have, the type of soil, the height of your grass and the weather in your region.

:small_blue_diamond: Always make sure that all the grass gets the same amount of water. And remember that you need more water during the hot summer months to keep your grass moist.

Understanding Water Needs for Established Grass

:small_blue_diamond: Grass management is a year-round process, and it is important not to underestimate the value of water in the established grass.

:small_blue_diamond: Grass need 1-2 inches of water per week. At certain times of the year, Mother Nature can provide enough rain to keep your grass growing. However, dry spells are usually present for several weeks or more.

When the grass is not getting enough water, you will often notice the following symptoms:

  • The colour changes from strong green to blue-green (and later, brown).

  • After traversing your lawn, you can see the footprints on the grass that will not stand back up.

:small_blue_diamond: Established grasses can withstand a few weeks without rain or irrigation, and it is common for grasses to fall asleep as a response. When the grass starts to get water again, the grass will start to grow again, and the colour has to come back. However, don’t be completely surprised if your lawn doesn’t return to normal. As you begin to irrigate your lawn, you may see small areas or ■■■■ areas where the moisture has not been present for a long time.

:small_blue_diamond: Although grass may emerge during short-term droughts, there are long-term consequences of not having enough water on the grass. As grass areas become weaker and thinner, weeds will quickly fill in the gaps. Weeds will grow and take up large areas simply because the grass did not always get water.


Understanding the best time to water your grass, especially on a hot summer day, is essential for maintaining your grass. However, it is always good to get a reminder of the basics.

How to avoid water runoff

There can be a complete book written on all methods of combating wastewater and water runoff. But we will try to wrap the novel into a few valuable points.

:ballot_box_with_check: Be aware that your problem areas (i.e., slopes, sunny areas, areas along sidewalks, and under trees) will need more water and help than other areas.

:ballot_box_with_check: Allow your grass to grow longer, and do not cut it shorter during the hot months. Avoid cutting more than one-third of a piece of grass at a time.

:ballot_box_with_check: Annually aerating your grass and applying a thin layer of compost will help improve soil quality in more compacted grass. The most common occurrence is in Denver clay soil.

:ballot_box_with_check: Assume that shady areas, lowlands, and areas that receive the flow of your neighbours will not require much water. Knowing those areas will allow you to adjust your spray system accordingly.

:ballot_box_with_check: Measure your spray system to work long enough to irrigate each area at least an inch. Also, allow the spray heads to separate the areas slightly to ensure adequate watering.

:ballot_box_with_check: You can use tuna cans to measure how long it takes for each area to irrigate a full inch. Track the timing of each location and set the timer to work for that long in each zone.

:ballot_box_with_check: It is also a good idea to set aside space for your irrigation twice a week. Add five inches of water each time.
