Q: I notice neighbors’ sprinklers running at all hours of the day. What’s the best time to water grass, and how much water is enough?

A: When to water your lawn is no longer just a question of how to get the greenest, most pristine grass in the neighborhood (though it remains a factor). With many communities experiencing drought in recent years, it’s more important than ever to heed common-sense guidelines when watering a lawn. Doing so correctly can save resources while keeping you out of hot water with your homeowners association and even your city. In areas where HOAs and municipalities enforce strict rules, wise watering can save you from fines as well.

Early in the morning is the best time to water grass.

Watering grass during the day, preferably at sunrise when everything is cooler, will ensure optimal water absorption. Watering grass at night or later in the day—particularly if it’s bright, warm, and breezy—means that the wind and heat of the sun and soil will rob your grass and other plantings of precious hydration. Water is less likely to evaporate in morning’s lower light and temperature, so you waste less. If you get the job done at dawn, you’re giving the water a greater chance of reaching the roots and being fully utilized. So set those sprinklers accordingly.

Water newly planted grass seed twice daily to help it take root.

Grass seeds require constant moisture and tend to grow best in temperatures ranging from 59 to 69 degrees Fahrenheit. These conditions help them germinate. Depending on the variety of grass seed planted, germination takes 5 to 30 days.

The goal with watering grass seed is to keep the top 1.5 inches of soil moist, but not soggy, all the time. The right amount of water is crucial for helping the sprouts take root. Not enough water dries out the sprout and kills it, whereas too much water can puddle or run and wash away the seed, creating clumps or bare spots. In general, water grass seed twice a day for 5 to 10 minutes, once in the morning and once in the afternoon after the hottest part of the day has passed.

The amount of water you use is also critical.

It might seem smart to set your sprinkler or irrigation system to the highest setting and drench the area as rapidly as possible, but if you water too quickly, you can experience runoff. This robs the lawn of ample absorption and wastes water in the process. So keep an eye on the edge of your lawn to make sure you’re not literally letting precious water run down the drain when it could be helping your grass grow.

Cool-season and warm-season grasses have different watering needs.

Cool-season grasses are often found in cooler, northern climates or planted in the off-season of warmer ones. These grasses start growing when the soil temperature reaches about 40 to 60 degrees Fahrenheit, with peak growing seasons in the spring and fall. When watering a lawn of cool-season grasses, you typically need about 1 inch of water per week. This can be achieved by watering three times each week at regularly spaced intervals.

Warm-season grasses make their home in warm, southern climates. These types of grasses start growing when the soil temperature hits between 60 and 65 degrees Fahrenheit, reaching their peak growing season in the summertime. As a result of their heat tolerance, warm season grasses develop deep roots. When watering a lawn of warm weather grasses, only give them only ½ to 1 inch of water per week. These types of grasses only need to be watered once, maybe twice, each week.

Follow the general rule of one inch of water every week.

More than an inch of water a week can drown your grass, depleting it of oxygen and causing it to die, so measure your output and wait about 3 days between each watering session to give it a chance to breathe. To ensure you’re hitting the mark, place a few coffee mugs around your yard and test the sprinkler system to see how long it takes to fill each cup to the ⅓- or ½-inch mark.

Then, set the system for that same amount of time every 3 days or so. Watering daily is almost always too frequent, while once a week is rarely enough. So aim down the middle and watch your lawn flourish.

Water your mature lawn one to three times per week.

Your lawn-watering schedule depends on whether you have warm-season grasses or cool-season grasses. The extensive root systems of warm-season grasses grow deep into the soil and require less frequent watering. You want to water these grasses as infrequently as possible.

Cool-season grasses, on the other hand, have a shallow root system, and therefore require constant moisture. Watering up to three times each week can help the roots obtain the nutrients they need to grow.

Keep an eye out for dryness.

Grass that’s discolored or curled over at the top is likely suffering from a lack of moisture. The same is true of a lawn that still shows your footprints after you’ve trod a path across it, with the grass blades refusing to bounce back up. If you notice these signs of dryness, adjust your lawn watering schedule to start earlier in the day and allow for slightly longer sessions, or perhaps fine-tune your watering days to occur a bit more frequently.

Watch out for overwatering, too.

If the ground feels particularly sponge-like and your feet sink in as you walk across it, or if you see a thatch of extra vegetation taking hold of your topsoil when you run your hand over the blades, you’re watering a lawn too much. However, when modifying your frequency, don’t do so abruptly. Take a few weeks to slowly adjust your lawn watering schedule to keep the shock of change from further ruining your lawn.

Looking to cut back on water use? Consider xeriscaping or native landscaping.

Xeriscaping involves landscaping that requires no or minimal watering, often using sand, pebbles, mulch, or rock gardens where grass would otherwise be found. Native landscaping involves grasses and plants that thrive naturally with typical local rainfall, reducing or eliminating the need for extra watering. You also can check with local sources to find grasses native to your area and grow a small patch for kids and dogs to enjoy.

Both xeriscaping and native plants are attractive and effective ways to cut back on your water bill, and some homeowners choose to combine the two for a beautiful, eco-friendly landscape that demands little upkeep. Plus, you don’t have to worry about the best time to water grass in summer heat or winter conditions; instead, you’ll have a landscape well suited to the elements in your region year-round. Whichever approach you choose, best of luck with your outdoor space!

Final Thoughts

The best time to water grass is in the early morning, which gives the water time to absorb before midday heat, and helps deliver the nutrients and oxygen the grass needs to thrive. Do the research to find out more about your lawn and the type of grass you have to provide the care it requires. Understanding the needs of your grass or grass seeds will help you determine how much water you need.

Be sure to water thoughtfully, which better manages your water resources, and helps your lawn grow. Take care to avoid overwatering, which can push essential nutrients out of reach of the roots, along with underwatering, which can create dried-out patches on your lawn.

With the right amount of water delivered at the best time of day, your lawn is sure to see an improvement.

FAQs About the Best Time to Water Grass

Learning and implementing the best time to run sprinklers in your yard makes a big difference to your grass. To gain a better understanding of how to help your grass grow, and how to water it properly, here are some frequently asked questions and answers about the best time to water grass.

Q: Does watering grass in the sun burn it?

A common misconception about watering grass in the sun is that the water droplets act like a magnifying glass, burning the grass beneath it. Dry spots on your lawn form when they receive insufficient water. Watering in the heat of the day causes the water to evaporate faster, so your lawn isn’t getting as much moisture as you think it is, which is why the best time to water grass is early in the morning.

Q: Should you water grass after mowing?

You should only water your grass after mowing if you notice that your grass is in dire need of moisture. If your mowing schedule coincides with your early morning watering schedule, by all means, water your grass after mowing. For those who prefer to mow their lawn during the day, wait to water the grass until the next morning.

Q: How often should you water grass seed?

Grass seed needs to be watered at least twice a day to help the seeds germinate. This process takes 5 to 30 days depending on the variety of grass, so follow the grass supplier’s instructions. The goal is to keep the top of the soil consistently moist to help the seeds germinate and sprout into grass.

Q: How deep do grass roots grow?

The depth of grass roots depends on the variety of grass you are using. Many grass roots are found close to the surface, as little as a few inches deep. With mature lawns that have time to grow and establish themselves, grass roots can be as deep as 3 feet.

Q: What’s the best time to water grass seed?

The best time to water grass seed is in the early morning and in the afternoon after the hottest part of the day has passed. In warmer or drier climates, you may have to water more often. Grass seed requires constant moisture in the top 1½ inches of soil to help the seed germinate.

Best Time to Water Grass

Green and lush lawns can be hard to maintain and care for. And when your lawn isn’t growing as green or as thick as you would like, it can be hard to know why. Often, the grass might be struggling because it’s not getting enough water or not getting water at the right time. Or maybe your grass looks fine, but you want to know how long to water turfgrass or the best time of day to water your lawn to help save water. Read on to learn about the most common watering mistakes you might be making with your lawn, the best time to water grass, and how to remedy them to help your lawn grow healthy and strong.

Watering the Right Amount

Many people water too much or too little. How much water does your lawn actually need? You might think that the amount of water each lawn needs varies, but it actually doesn’t vary much. Your lawn needs about 1 -1 ½ inches of water each week to grow healthy and strong. More water than that can cause your yard to get saturated, which is one of the leading causes of disease, fungal growth, and soil compaction, all of which can result in unattractive, unhealthy grass. Too little water will dry your grass out and turn it yellow and parched. The key is to try and give your yard about that ideal inch of water each week – even during the winter. Watering the lawn is a year-round project.

The good news is that if you live in a wet environment, you may not need to use sprinklers at all. If your lawn gets 1 -1 ½ inch of precipitation a week, then you don’t need to water your lawn yourself. Most people don’t need to water their lawn in the winter because the natural rainfall or snow acts as the weekly precipitation the lawn needs.

Best Time to Water Grass

Some people aren’t sure when the best time to water grass is, and they end up watering at the wrong time. When is the best time of day to water lawns? You might see sprinklers in your neighborhood going at all hours of the day and wonder who is watering at the right time. If you’re wondering when to water grass, the best time to water grass lawns is in the early morning between 4 AM and 9 AM. Watering in the cool morning will reduce the amount of evaporation that occurs while you’re watering, so your grass can soak up more water in less time. This trick will save you on your water bill. Avoid watering at midday, (when water evaporates too quickly) and late at night (which can lead to fungal growth). Also, watering during the heat of the day can cause the water to evaporate before it even reaches the roots, so your

Additionally, watering in the early morning gives your lawn enough time to dry before dark. Lawns that are still wet at nightfall regularly can experience lawn fungus and disease. Watering in the early morning will prevent this from happening. The best time to water grass is in the early morning during cooler temperatures, but if it’s impossible to water in the early morning, it’s better to water it at some point during the day than not at all.

Watering Often Enough

It might seem like you should water your lawn every day. The more water the better, right? But watering your grass every day can weaken the root system in your yard. The daily watering can cause the root system to become shallow and dry out fast. Overall, watering too often will weaken your lawn. On the other hand, watering too infrequently can cause the roots to dry out and the lawn to yellow. The key is to water just a couple of times a week to help keep your lawn moisturized and healthy.

Since lawns need about 1 -1 ½ inches of water a week, you can divide that between two or three watering sessions of about half an inch each time. During winter weather or colder conditions, lawns only need to be watered once or maybe twice to maintain the right amount of water.

How Long to Water Your Lawn

Some people worry about watering for too long, or they overcompensate and water their lawn too much. Now you know how much water your grass needs and when to water it, but you still may wonder how long to water your lawn to give it that key 1 -1 ½ inch. There can be some variation between lawns, but generally, it takes about half an hour to give your grass ½ inch of water. If you decide to water your grass three times a week, you only need to water about 20 – 30 minutes each of those three times.

There is a test to help determine exactly how long to water lawns to tailor this rule of thumb to your grass. Place a container or can of some kind in your yard and run your sprinklers. Set a timer to see how long it takes for an inch of water to be in the container. However long that takes is about how long to water your lawn through the entire week. You can then divide that time between two or three times to help spread out the watering.

Watering Grass Seed

When it comes to watering grass seed, a lot of the same watering rules apply. Grass seed should be watered early in the morning and other cooler times of the day. But there are a couple of tips for watering grass seed that isn’t an established lawn.

Water once per day for 2 -3 days before planting the grass seed.
Water once for 10 minutes right after planting.
Water both morning and evening for about 10 minutes until the seeds sprout.
Water like usual once the seeds have sprouted.

Watering grass seed is similar to regular lawns, but these tips should help your grass seed flourish into a healthy yard.

How to Tell if the Grass is Watered Enough

Once you are watering your lawn 2 – 3 times a week for about twenty minutes, you may want to check if your lawn is getting enough water. The easiest way to check is to see if your lawn looks healthy. If it’s green and lush without any brittle grass, it’s most likely getting enough water. Another quick way to check is to stick a screwdriver into the soil. If it sinks 6 – 7 inches in, then your yard is getting enough water. If it doesn’t go far enough in, then your lawn might need a little more water.

You can often tell if your lawn is being overwatered if you are finding mushrooms. If you see mushrooms peeking out from the blades of grass, it’s time to try reducing the amount you water a little bit.

The Bottom Line

These are the common mistakes people may make while watering their lawns. Watering the right amount, at the right time, and the right amount will help your yard flourish. Watering 1 inch a week and during the ideal times will keep your grass healthy and green. The next step is to fertilize and mow at all the right times. All of these steps together will help you care for your lawn and keep it healthy and strong.

Features of watering the lawn in the heat

A common question from gardeners is how to water the lawn in the heat? To answer the question, we wrote a small guide in which we collected answers from the company's experts and based on the experience of foreign colleagues: how the lawn behaves in the heat, how often to water, and most importantly, what tools will be needed for watering. Thanks to the article, you can easily determine when it's time to water, how to do it, and then spend time in the country. nine0004

How do you know when it's time to water your lawn?

One way to tell if a lawn is hot and lacking moisture is to look at its color. The grass changes color from rich green to grey-green. The second way to determine that the grass needs watering is to dip a pencil, screwdriver or knife into the soil to a depth of 7-10 cm. Any item that you have at hand will do. If the pencil is lowered and pulled out gently, then there is enough moisture at the roots. If with difficulty, then it's time to properly shed the lawn. nine0004

Thanks to regular lawn care, you will learn to determine its “rhythms” without additional tools.

How often should you water your lawn in hot weather?

The frequency of watering the lawn in the heat depends on the weather and soil type. If the weather is hot and dry, with air temperatures up to +30 degrees, you can water the lawn 2-3 times a week. If the temperature is +35 degrees and above, without rain, we recommend watering daily. But it is important to ensure that the earth has time to dry out between waterings and the roots of the plants receive enough air, which will favorably affect the growth of their root system. nine0004

Drought gets to the lawn faster on sandy soils than on other soils. Because water doesn't last long. Therefore, watering is needed more often.

It is better to water the lawn in the shade less often so that the water does not stagnate.

Be careful when watering the lawn in the shade: the water drains more slowly and the lawn may weaken.

Daily watering is safe for the lawn and even, on the contrary, cools it. Drops that remain on the grass do not work as lenses and do not leave burns. It is a myth. nine0004

How much water is needed for watering in the heat?

On average, this is 10-20 liters per 1 m ² . The volume depends on how long you watered and how long the heat is. For a long time, then we take the upper limit, if not, then the lower one. If the soil is dry, then at least 40 liters of water are needed per square meter of lawn.

To check if you have shed enough lawn, step on the grass with your foot: if the water is standing, then you did everything right

In fact, the volume of watering is not so much important as its uniformity. If you water the lawn by hand, then in some places you can pour more water, and at the edges you can not shed the lawn at all. To avoid this, we recommend installing one of the automatic watering systems.

The best way to irrigate is not with powerful jets of water that wash the soil from under the roots, but with small sprinklers that allow small, thin sprays to thoroughly cover the entire surface of the lawn. nine0003

Regular watering of the lawn in the heat is the key to its healthy look and freshness

What can you use to water your lawn?

There are different irrigation systems. Their choice depends on the size of your site. If you are watering a small piece of land, for example 4 m ², then using a garden hose is sufficient. But if the irrigation area is larger, then it is already more convenient to connect drip irrigation systems.

More often you may come across automatic systems with different types of sprinklers. Each of them has its own advantages and disadvantages. We recommend choosing according to your budget and area of the site. nine0004

GARDENA Aqua S Oscillating Sprinkler

Suitable for watering a plot from 90 to 220 m2 ²

Buy

nine0025 GARDENA Premium Pulse Sprinkler

There are 3 types of irrigation system with sprinklers: rotary, rotary, fan. And they are also divided by location: above-ground, retractable and contour. Which one to choose depends on the size of the plot.

We will discuss in more detail about irrigation systems and their types in another article.

So, let's repeat the most important thing about watering the lawn in the heat:

Determine the state of the lawn in the heat: retains color saturation or changed it to gray-green or yellow
Check if the soil is deeply moistened. To do this, take a pencil or a knife to pierce the ground to a depth of 10 cm.
Take a break between waterings. In the heat, abundant watering is needed, but with pauses so as not to flood the plants and so that the roots receive enough air nine0004
Make sure that the lawn is moistened evenly: water gets both into the center of the plot and along its edges
You can water in the heat both in the morning and in the afternoon. Drops on grass don't become lenses - that's a myth. On the contrary, in the heat you will help the lawn to cool down.
Adjust watering according to natural rainfall.

Thanks to the recommendations in the article, your lawn will never suffer from the heat!

To create a green lawn in your summer cottage, you can choose a rolled lawn. Or consider lawn grass seed options for any budget and purpose if you want to grow your own lawn.

How much to water the lawn and how often should it be done? Answers from Green Roll

In the new video, Vadim Abakumov tells what the correct automatic watering of the lawn should be like. It is important not only to lay pipes and set up automation, but also to comply with a number of requirements so that your lawn is always in great shape. This time we went to the site where the American Rain Bird automatic irrigation system was already installed, the first mowing was carried out. With a concrete example, we will show how to water the lawn and when it is best to do it. nine0004

It is believed that it makes sense to install automatic watering of the lawn if the area of the plot allotted for turf exceeds 5-6 acres. Smaller lawns can be well watered by hand or with sprinklers from Gardena or another manufacturer of garden equipment. If you are the owner of a large lawn, a sports ground or a mini-football field, you cannot do without special equipment. Entrust its installation to a reliable trusted company.

Now that the equipment is installed, it is important to follow the basic watering rules. As a rule, immediately after laying, the first 5-6 days, abundant watering of the rolled lawn is required, until a slight stagnation of water on the surface is required. Then reduce the number of waterings and maintain the lawn on schedule, turning individual sprinkler zones on and off.

Here are the most important rules to follow in order to achieve a flawless result.

We are often asked how much to water the lawn so that the soil is sufficiently moist, but not flooded to the state of a swamp. The optimal duration of watering for one zone is at least 30 minutes. Water must be absorbed and reach the roots, otherwise it will remain in the top layer, which will provoke the growth of weeds and moss. If you reduce the watering time to 15 minutes, the grass on the lawn will begin to turn yellow, despite the regular operation of the system. nine0110
The second important point is the frequency of watering. The irrigation system should not be turned on daily. The lawn must be dry. If spots of darkened grass appear on it, it's time to get down to business. As a rule, in the summer it is enough to water the lawn once or twice a week with an interval of several days.
