How Much To Water

How Often Should You Water Your Lawn?

Thoroughly wet the soil to a depth of 6 inches with each watering. Shallow watering produces weak, shallow-rooted grass that is more susceptible to drought stress.

Soil type, sprinkler style and water pressure determine how much water is needed to wet the soil to a depth of 6 inches and how long a sprinkler must run. Use the following steps to determine how long to run your sprinkler or irrigation system.

  • Set five to six open-top cans randomly on the lawn .
  • Turn the sprinkler head or system on for 30 minutes.
  • Measure and record the depth of water caught in each individual can.
  • Calculate the average depth of water from all of the cans. For example, you have used five cans in your yard. The amount of water found in the cans was as follows: 0.5 inch, 0.4 inch,0.6 inch, 0.4 inch, and 0.6 inch. Add the depths together and then divide by the number of cans you used
  • 1.5inch + 0.4 inch + 0.6 inch + 0.4 inch + 1.6 inch = 2.5 inches, 5 cans = 0.5 inch of water in 30 minutes
  • Use a garden spade or a soil probe to determine how deeply the soil was wet during the 30-minute time period. The probe will easily push through wet soil but less easily into dry areas.
  • From the amount of water that was applied in the 30-minute cycle and the depth that it wet the soil, you can then determine how long the sprinkler must run to wet the soil to a depth of 6 inches.
  • How Do I Know If My Grass Has Enough Water

    There are a few ways you can tell if youve given your lawn enough to drink:

    • Check the soil every 15 minutes during your first watering to see how long it takes to get soaked. Use a shovel or screwdriver to get a measurement, and when youve determined the water has gone six inches deep, note the time. Thats how long it should take in the future.
    • If you have a sprinkler system, find out its flow rate from the manufacturer. Multiply the square footage of your lawn by 0.62 gallons then divide that figure by the flow rate. The result will tell you how many minutes to run your sprinkler.
    • Place empty tuna cans around the lawn and measure how long it takes for the sprinkler to fill each can with an inch of water. The sprinkler coverage will vary, so use the average time it takes to fill the cans.

Watering a lawn seems like a simple enough task, but for most of us knowing the best time to water your grassand how long to water your lawncan be confusing.

    To provide you with a time-proven, easy-to-follow strategy for watering lawns, we contacted lawn care expert Matt Maurer, owner of PureLawn Lawn Services, with branches in Cincinnati and Dayton, Ohio.

    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.

    Water Deeply But Not Too Often

    • Too much watering can lead to poor growing conditions and disease problems.
    • Water only when your lawn needs it, usually no more than once a week when there is no rainfall.
    • Apply at least 2.5 cm of water. Put a tuna or pet food can on your lawn to measure how much you’ve watered. Stop watering when it’s full.
    • Consider the soil type and surface features. Grass growing on compacted, fine soil or on slopes needs lighter, more frequent watering.

    How Can You Tell If Your Lawn Has Had Enough Water

    How Much and How Often Should You Water Your Lawn ...

    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.

    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.

    Signs Your Lawn May Be Overwatered:

    Fungi: One of the most telltale signs that a lawn is overwatered is the development of lawn disease and fungus created by too much moisture always living in your grass. When a yard is overwatered, the grass is unable to ventilate, and stagnant water occurs. Lawn disease and fungus most commonly look like ugly brown patches of grass throughout your lawn. If these patches are not treated quickly, they spread and can ultimately damage an entire lawn.

    Lackluster Lawn: Healthy grass requires oxygen as much as it does water. When a lawn is overwatered, it cannot use the pores to absorb oxygen and continue to grow.

    Weeds: These unwanted plants thrive in moist conditions. Because weeds can grow more quickly than grass, overwatering puts your turf at risk for higher weed growth.

    Insects: Just like weeds, insects flock to overly watered lawns to lay their eggs and breed.

    When And How To Water Your Lawn

    When to Water: How to Know When Your Grass Needs Water:

  • Step Test: Step on the lawn. If the grass doesnt spring back right away, it needs water. If it pops right back up, it already has plenty of water.
  • Curled Blades: Look at your grass. If you notice that the blades are curled, your grass is water stressed, and it is time to water.
  • Change in Color: It may sound basic, but if your grass is starting to lose its green color it is time to water.
  • How Often to Water:

  • Ordinary Seed: Water 1-2 times a week, applying a total of approximately 1 inch of water each week based on your location and time of year. Watering 1- 2 times per week is more beneficial than light watering several times a week. Light watering promotes shallow roots, which make plants less drought tolerant.
  • PenningtonSmart Seed. These grasses are specifically bred to be drought tolerant. Smart Seed requires up to 30% less water year after year versus ordinary grass seed.
  • How to Know if Your Grass is Getting the Right Amount of Water:

  • Can Test: Place multiple water gauges or tuna or cat food cans on the lawn. Run your sprinkler or irrigation systems for 15 minutes and measure the water in the catch basins. This will help you determine how long you need to run your sprinklers or irrigation system to make sure your lawn is getting the right amount of water.

    The Best Time To Water Your Lawn

    How often should you water your lawn ?

    If you notice that your lawn has a grayish tint or appears to have a dull green color, this is a sign that it needs water. During certain times of the year, water is unnecessary because there is enough precipitation to provide the lawn with all the water it needs. However, at other times drought and heat make regular watering essential.

    Depending on where you live, you generally won’t need to water your lawn until June. In general, you can start watering it from late spring through early fall.

    How long should sprinklers run in Texas? For established St. Augustine grass, the first and last three months of the year will only require about five hours of watering every two to three weeks. During the middle of the year, run your sprinkler system for around five hours every week to keep your grass from burning out.

    What To Look Out For

    Watering a lawn isnt a set routine which can be applied to every garden from Perth to Plymouth it can depend on a number of factors and may vary significantly from garden to garden. The main factors to consider are location, soil type, shade and other things that may be present such as tree roots, however its best to look at a few key things when assessing whether your lawn needs a top up. The first sign of dehydration is when grass begins to lose its springiness and is very flat after being walked on, but the most obvious thing to look out for is when grass begins to yellow. If theres no rain being forecast any time soon then it may be time to water and if done correctly your lawn should bounce back almost immediately.

    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.

    When should I fertilize my lawn in Texas? Begin fertilizing 3 weeks after the grass turns green and when there is little chance of a late frost. Apply 1 pound of soluble nitrogen per 1,000 square feet of lawn every 8 weeks, or 11/2 pounds of slow-release nitrogen every 10 weeks. Have your soil tested to determine what added nutrients your lawn may need.

    When During The Day Should You Water Your Lawn

    Its best to water your lawn in the early morningbefore 10 am at the latest, and ideally between 4 am 9 am. This gives time for the water to soak in before the day gets hot. If you water during the middle of the day, the water will evaporate quicklymeaning its less likely to reach the roots of your grass.

    Avoid watering your lawn at night time, because this can encourage the growth of fungus.

    How Can You Tell If Youve Watered Your Lawn Enough

    The average lawn needs at least 1 inch of water to 1.5 inches of water per week. This should be continued throughout the year. Even lawns in winter need water as you cant always guarantee that the rainy weather will give them enough.

    To be able to figure out if it has enough water, you should get a rain gauge. This will show you just how much water the grass is getting. If using a sprinkler system, make sure that the water from the sprinkler is going into the rain gauge. This will allow you to measure the amount of water that the grass is getting.

    The best thing for your lawn would be to water it twice per week, but water it lots, making sure it has 1 inch of water. By watering it a little every day, the grass roots will be shallow, making it difficult for the root system to support the grass. It can also lead to fungus growth in the lawn.

    How Often Should You Water Your Lawn And How Much

    Create a weekly water schedule and routine and follow it year-round. While your grass will go dormant in the winter, it can still dry out and over stress with damaging effects. To ensure your lawn is getting at least an inch a week, buy a rain gauge that stakes into the grass and measures in inches. You dont need anything fancy, so try looking somewhere like Amazon. They have some for as little as $3.99, like the Lacrosse 704-110 Patina Rain Gauge.

    Stake the gauge somewhere inconspicuous but accessible where the water always hits. If youre reaching an inch every week, youre good. If not, water more. If it rains while youre measuring, start again next week.

    Daily watering is always a bad idea, even if you live in a hotter part of the country. When you water daily, your lawn develops a shallow root system, making it less hardy in the high heat of summer. Aim to water 2-3 times a week, making sure you hit the 1 mark.

    How Many Times A Week To Water

    How much and how often you should water your lawn.

    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 Dry Is Too Dry

    Conserving water is a good idea. Golf courses do it. Homeowners should do it, too. But how long can you let your lawn go without?

    As with so much else in turf care, it depends. A hardy grass like Bermuda is camel-like in this regard: It can survive long bouts of deprivation. Not so with bentgrass in searing summer heat.

    In drought conditions, grass does what it does in colder seasons: It goes dormant as a means of self-protection, redirecting moisture and nutrients to its roots. Its leaves turn color as a result. Dormant grass can be brought back to life just add water.

    But dead grass? Well, dead grass is dead.

    As with so much else in turf care, the durability of your lawn depends on many factors. But as a general rule, Cutler says, grass starts going dormant after two weeks without water. After a month, its apt to die.

    How do you tell if your grass has crossed that line? One faithful indicator is its crown. Thats the thick, light colored part of the plant, just above the soil, right where the roots meet the shoots. Look closely. If theres still green in the crown, theres still life in your grass. If not, you might be out of luck.

    Another way to tell is pretty simple, too: tug on the grass, Cutler says. If its roots remain intact, its probably still alive. If it uproots easily, its toast. Youll need to reseed to get it back.
