If your lawn gets liquid fertilizer, wait until it dries before watering, about 2-4 hours.If its granular fertilizer, water right away. One exception: if you also got spot weed treatments at the same time, wait for that to dry before watering, or the water will wash off the weed killer before it can work.

Six Weeks After Hydroseeding The Lawn

If four to six weeks pass and your lawn looks on track and healthy, then it is okay to stop watering the lawn so frequently. Depending on the lawns health and the heat, You can scale your watering all the way back to half an hour every week. If the rain comes for one day in a week, you do not have to water your lawn that week.

Let the rain take care of your hydroseed lawn, and do not add any extra moisture. In the first six weeks, the mulch needs to be slightly moist at all times. Now, allow the lawn and the mulch to dry out. Just be sure to water every section of the lawn thoroughly when it is time to water it.

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 grasses

Warm-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 grasses

Cool-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.

How Much Water Does My Lawn Need

Many homeowners arent exactly sure how much water is necessary to keep plants thriving during the summer. Heres the short, frustrating answer: it depends.

What factors dictate your summer water requirements?

A few variables are your soil type, grass type and how much shade your lawn gets.

Generally speaking, lawns with more shade or clay soil dont need as much water. However, if your soil is porous and sandy, your lawn will probably need more water.

You can determine what kind of soil you have in your lawn by doing a test. There are a number of ways to do this, but Texas A& M will test your soil for no charge if you send in a sample.

Want a ballpark figure, just to get an idea? Most lawns need somewhere between three-quarters to one and a half inches each week to stay green and healthy.

Now, an even more important question: what does that mean in terms of how long and how often you should water?

How Much To Water Your Lawn

How Often Should I Water My Lawn?

Watering the proper amount is criticaloverdo it, and your grass, your water bill, and the environment will suffer. The amount of water you need is generally 1 to 1.5 inches per week, but it can vary depending on your grass type, the climate you live in, your soil type, and the age of your lawn.

Established Lawns

In general, you want the top 6-8 inches of soil to be moist, but not soggywhich translates to 1 to 1.5 inches per week. Watering deeply, but infrequently, leads to stronger root development and drought-resistance than watering briefly every day. You can break up these waterings into twice a week during most of the year, or three times a week during the hot summer months.

Newly Seeded or Sodded Lawns

To encourage proper growth, newly seeded or sodded lawns need moisture in the top inch of their soil, but not so much that they turn soggy. Instead of watering a few times a week, you will need to take a mister and gently spray the newly seeded areas once to two times a day, depending on the weather.

As the seeds germinate, keep the top 2 inches of soil moist. Once the grass grows to a 3-inch mowing height, you can reduce watering to twice a week. Then, you should soak the soil down 6-8 inches, like you would an established lawn.

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!

The Consequences Of A Lack Of Water For Your Lawn

How Often Should You Water Your Lawn?

When the lawn is left unwatered for an extended period of time, the lawn seeks protection from water stress and goes dormant. It therefore stops growing, which causes the appearance of a dark yellowish or brownish color. At this point, the leaves and stems dry out and turn brown, but the underground parts still remain alive.

In general, a well-maintained lawn can survive summer droughts without the need for irrigation. However, after 4 weeks without water, it is very likely that your lawn will take on a yellowish or orange tint, which means that it is seriously dried out and needs urgent watering.

How To Tell If Your Grass Isnt Getting Enough Water

There are several tell-tale signs that you need to water your lawn. Its simple as can be, but if your once-vibrant green lawn has taken on a gray shade, you need to water. Curled grass blades are another indicatorit means your grass is thirsty.

If youre unsure, consider tackling one of two tests. For the step test, simply walk on your lawn. If your lawn is well-watered, your grass should spring right back up where youve stepped. If it doesnt, its lacking moisture, so it needs water.

The screwdriver test is another classic. See if you can drive a long-bladed screwdriver 6 inches into the soil. If you cant push the tool down that far or you meet a lot of resistance, its time to water.

The absolute best time to water your lawn is the early morning, before 10 a.m., says Maurer. Cooler temperatures and calm breezes help keep evaporation to a minimum. And watering in the morning keeps the turf cooler during the hottest parts of the day, which means less stress on the grass.

As a general rule, you should water long enough to moisten the soil down to about 6 inches, which is the average depth of a healthy grass-root system. It takes about one inch of water to properly hydrate normal lawns to that depth. But, Maurer warns, “Each lawn has different soil. You have to water for your specific property.” There are a few ways to determine whether your lawn is getting the right amount of water.

Watering Cool Vs Warm Season Grasses

You need to care for different grass types in different ways to keep them at their healthiest and hardiest.

Cool Season Grasses

These types of grasses, like fescue, rye, and bluegrass, grow actively in the fall. Theyll need about 1-1.5 inches every week until the growing season ends, roughly when the first frost sets in. If you dont water cool season grasses during a drought, they will go dormant but re-green when it starts raining again.

Warm Season Grasses

Warm season grasses, including bermuda, St. Augustine, zoysia, and centipede grass, do most of their growing in the summertime. Overall, they require less water than cool season grasses, but even they need extra water in the dead heat.

When watering a newly seeded lawn, the key is to keep the top inch of soil consistently moist but not soggy. You will likely need to mist the seeded area once or twice a day . Once the seeds start to germinate, continue to keep the top 2 inches of soil moist until the new grass reaches a mowing height of around 3 inches. After that, begin to cut back watering to twice per week and soak the soil deeper, about 6-8 inches, to encourage the grass roots to grow down deep into the soil.

    How Long Should I Water My Lawn

    If you want the most accurate answer for how long you should be setting your sprinklers to run, you can follow these steps:

    • Put some small cans out on your lawn in each watering zone.
    • Run your sprinklers in each zone for 15 minutes.
    • Measure the water depth for each zone by checking the amount of water in the cans.
    • Multiply that number by four to determine the hourly precipitation rate. For example, if you have one and a half inches of water, you would multiply that number by fifteen to get 6 inches per hour.
    • Select the station thats closest to you on Texas A& Ms online tool.
    • Select Home Owner on the next screen.
    • Fill out the Home Owner Calculator that pops up. For Step 3, use the hourly precipitation rate you measured using your cans.
    • Hit Calculate and you will be given the total run time and the run time per irrigation station, depending on how many times per week you plan to run your sprinklers.

    Want an example?

    Lets say you have a lawn that receives full sun, has St. Augustine grass and got very little rainfall in the last week. Using the weather evapotranspiration data in the online tool, you would need to run your sprinklers for a total of 41 minutes each week. So, if you water twice a week, that would be 21.5 minutes each time .

    When To Water Your Lawn

    How Often Should I Water My Lawn?

    As youve probably heard, watering early is the way to go. Cutler recommends the window between 5 a.m and 10 a.m., and for a couple of reasons. Not only do you want to beat the heat of day, when too much H2O gets lost to evaporation, you also want to get the job done before the wind kicks up and messes with your sprinkler patterns, making it tough to water evenly. Breezy conditions = inefficiency.

    Golf courses sometimes water in the dead of night, but thats out of necessity, Cutler says , and he doesnt recommend it. When you water after dark, you open the door to fungus and mildew, which creep in when moisture sits for too long on the grass.

    The perils of these problems are especially pronounced right after mowing, when turf is in a bruised and vulnerable state . So, when you cut your turf, allow it time to recover before you water . And, of course, if you mowed that afternoon, its an especially bad idea to water that night.
