How Much Water Should I Use
Remember that you dont need to worry about watering every day. Grass needs about an inch to an inch and a half of water each week, either from rainfall or irrigation.
Water the lawn until the top six or eight inches of soil is wet, which should give the grass the inch of water it needs. You can apply this inch in a single session or spaced out over two half-inch watering sessions during the week.
How Often Should A Lawn Be Watered
Jul 8, 2021 |
Proper irrigation can make a big difference in the health of your lawn. Most turfgrasses need about an inch of water a week. Use a rain gauge and monitor the forecast to help determine when to supplement rainfall with irrigation. To make this easier for you, add rain sensors to the irrigation system. Rain sensors will help ensure that water is conserved and only applied as needed. How often you water your lawn should be determined by your soil type because they retain water at different rates. Clay particles are tiny and hold onto water tightly. Plants have difficulty exerting enough force to break the bonds between the clay soil particles and the water when there is not enough water in the soil. So, it is best to deliver 1 inch of water for lawns with heavy clay soil all in one irrigation event. Sandy soils do not hold tightly onto water. Their large particles allow the soil to drain easily, and very sandy soils should get 1/3 of an inch of water three times a week. Sandy to loamy soils should receive around ½ inch twice a week. For help determining your soil type, see HGIC 1656, Soil Texture Analysis The Jar Test. For more information on irrigating different soils, see HGIC 1805, Landscape Irrigation Management Part 6: Soil Type & Irrigation Frequency.

The Best Time Of Day To Water Your Lawn
The best time to water your lawn is early in the morning since it is cooler and the winds tend to be calmer, so the water can be absorbed by the roots before it evaporates. If for some reason you cannot water in the morning, it is best to water between 4 p.m. and 6 p.m. rather than during the day or early afternoon. During the day more than 50% of the water evaporates before entering the ground. Make sure the blades of grass dry before dark to reduce the risk of fungal disease. Watering in the evening is not recommended!

Watering New Grass Vs Established Grass
If your lawn was recently seeded or sodded, there are different watering requirements than for an established lawn that has been planted for many years.
Whether you scattered seeds or rolled out sod, newly planted lawns will need to be watered more often. This ensures that the first two inches of soil remain constantly moist, promoting seed germination. You should use a mister to spray your new grass once or twice a day to keep the top layer of soil moist.
Established lawns should be watered one to 1.5 inches per week. Once a newly planted lawn is about three inches high, or mowing height, you can water it the same amount as an established lawn.

How Long To Water Your Lawn
The important question for lawn health is not so much how long to water your lawn at any given time as it is how much water to give your lawn.
To answer the question, it will take your sprinklers about one hour to put out the required one inch of water per week. Establishing a good irrigation schedule will help you achieve your lawn’s water requirements.
A related question is how often to water your lawn. You do not have to provide the required one inch per week all at once. Instead, you can water for 30 minutes twice a week. But some experts advise against extending irrigation sessions beyond that . Watering too frequently keeps roots too close to the surface. Less frequent watering encourages them to reach down deeper in search of water and aA deeper root system is less susceptible to heat stress and pest damage.

Your grass will certainly let you know when it needs watering if its been too long.
The results from watering when your grass has turned dull green or even brown are quite quick, versus the length of time it can take to fully treat rot or disease in an over-watered lawn.

In an ideal world, wed all have in-ground sprinkler systems that could run on a timer so that we wouldnt have to do much beyond planning the next watering.
They are one of the most effective systems and do an excellent job of evenly watering a lawn without wasting water. Most people dont have this luxury and opt for a sprinkler such as a pulsating or impact sprinkler, oscillating sprinkler, or rotary sprinkler to help distribute water across a larger lawn. For a small or medium-sized lawn, hand watering with a sprinkler nozzle on your hose can be an effective alternative it doesnt require much setup and allows you better control.
About an inch of water evenly over the lawn is ideal. For easy measurement, place a clean and empty tuna can in the middle of the lawn while you water. Once the tuna can is full, you know youve hit an inch deep.
Install Drip Lines And Rain Gauge
To ensure your entire yard is getting enough water, install drip irrigation lines for trees, shrubs and gardens, and install a rain gauge.
Drip irrigation is a great way to ensure smaller plants still receive deep watering without the risk of being overwatered by a sprinkler.
Likewise, a rain gauge will tell how much water the yard is receiving from rain and may even help you save on your water bill!

How Often To Water Your Lawn
Watering grass daily will result in a shallow root system. And shallow root systems dry out fast, weakening lawns. Infrequent, deep watering encourages grass roots to run deep, developing strong systems below-ground. This allows lawns to be more resilient to changing weather while becoming hardier and disease resistant.
The average lawn needs to be watered three times per week during warm months, providing a total of about one inch of water over the course of the week. Lawns can be watered as little as one to two times per week to achieve the same goal in cooler seasons, when there is naturally less evaporation and a higher chance of rainfall.

How Many Times A Week To Water
|
The frequency of weekly watering depends on your grass species, total water requirements for the week, and how long your soil will absorb water before running off into the gutter. Warm-season grassesWarm-season grasses have extensive root systems that penetrate deep into the soil and require deep and infrequent watering. Water as few times a week as necessary to fulfill your weekly water requirements without causing excessive runoff. Usually 1 or 2 times a week is sufficient. If you want to determine the maximum amount of time your sprinklers can be left on at one time, observe a cycle from the beginning to the time when runoff begins. That is the maximum amount of time that you let your sprinklers run in any given watering. Space out the applications evenly during the week. Cool-season grassesCool-season grasses require more frequent watering than warm-season grasses because their root systems are not as extensive. Divide the required weekly minutes into about 3 equal irrigations, evenly spaced throughout the week. Fewer applications may be sufficient during cooler months. Desert areas, slopes or areas with shallow soils also need shorter, more frequent irrigations than warm-season grasses. |
Local & Seasonal Weather
Weather obviously plays a large role in how often to water your lawn. Whether it is hot and sunny, rainy, or cold will dictate the needs of your grass. Most lawns do best with about one inch of water per week, however this may be a bit different if you are in a particularly hot and dry climate or if youre experiencing a lot of rain already.
Grasses can also become dormant under certain conditions. Dormancy is when the grass basically falls asleep it is not dead grass despite the misconception due to its brown colour or a duller shade of green. In temperatures below 40 degrees or above 90 degrees Fahrenheit, grass can become dormant and stop growing. In these kinds of temperatures, it may not serve much purpose to water a lawn until it warms up or cools down.

Watering The Wrong Amount
While overwatering is a common mistake, it happens to be one of the most detrimental. Unless watering newly planted grass seed, dont water every day.
Frequent, shallow watering wastes water and money. It also leads to a number of lawn problems, including diseases, insect infestations and damage from heat and cold. On the other hand, watering longer but less frequently, deep watering, produces deep roots that mean lawns can better survive periods of drought. The ideal watering schedule is once or twice per week, for about 25 to 30 minutes each time.
Taking care of a lawn doesnt have to be an overwhelming, all-consuming task. Once all the tips and tricks are in your back pocket, it will be easy to come up with a routine that results in a gorgeous green lawn.

How To Tell If You’ve Watered Enough
Check the soil: To see how long it will take to soak the soil, check it every 15 minutes during your first watering. Use a shovel or screwdriver to test how deep the water has moved. Mark the time once the soil has been soaked to a depth of at least 6 inches — thats how long youll need to water your lawn in the future.
Measure with cans: Place clean, empty tuna cans in different spots around the lawn and measure how long it takes to collect 1 inch of water in each can. Since sprinkler coverage patterns may vary throughout the lawn, use the average time it takes to fill all of the cans.
Use a flow timer : Choose a timer that measures water flow in hundreds of gallons. Multiply your lawns square footage by 0.62 gallons to determine the total number of gallons needed for the entire lawn.
When watering your lawn, you may begin to notice that your lawn isnt absorbing water as quickly as it should. If you find that puddling occurs whenever you water, try watering in shorter cycles until the required time to apply the needed amount of water is met .

How Frequently And How Long Should I Water My Lawn
This is determined by the soil type and sod type you have. In general, in the heat you should aim to soak your lawn on good water schedules, at least 2-3 times per week.
Provide around an inch to an inch and a half of water each week for most sod types. The right amount of water will vary depending on the time of year, what type of grass you have, the type of sprinklers you have, its settings, and of course, the weather where you live.
To get a good idea of how much you actually need to water, check the soil. You want the top six to eight inches to be moist, though not soggy. If you water deeply but infrequently, this will help your grass develop stronger roots that will withstand drought much better than if you were to water every day. Daily short watering can lead to shallow root systems.
The exception to this is if you are watering newly sodded or seeded lawns. These need to be misted lightly once or twice per day.
How do you know if your lawn isnt getting enough water? Its simple. The grass blades may look crunchy or brown.
You can also try the screwdriver test. Stick a long-bladed screwdriver six inches into the soil. If you are met with a lot of resistance, its time to water. There are also soil moisture probes that can be purchased and used to determine actual soil moisture.
Hint: Most all modern lawns sold today do not need to be watered daily. If you need to water daily to keep your lawn green in some areas you might have a sprinkler problem or a soil issue.
How Much Water Is Needed
As mentioned before, most lawns require 2-3 cm of water per week to soak the soil deeply. If you go over this amount slightly, don’t worry. Just make sure you don’t flood your lawn. Certain factors can influence the amount of water required, such as the type of soil. Clay soil retains much more water than sandy soil, and a lawn established on sandy soil is irrigated less but more often. Another factor is the climate. Naturally, more watering is required if you live in an area characterized by hot, dry air.

How Can You Tell If Your Lawn Has Had Enough Water
Simply making sure your sprinklers are on for long enough to deliver around 1.5 inches of water to your lawn is enough.
A simple way to check whether your lawn is getting enough water is to stick a dinner knife into the soil beneath your grass. If it slides in easily, then the grass likely has enough water. But if the ground is hard and dry, you probably need to increase the amount of water youre givingor how often youre watering.
Watering your lawn is one of those simple, routine tasks that can make all the difference to how your yard looks. You dont need to spend a lot of time or effort watering your lawn: a simple sprinkler system that you run 2 3 times a week is likely to be plenty.
