How Should I Water My Lawn
In general, lawns need approximately 1 to 1½ of water per week. Our experts recommend watering grass less often and more deeply. Giving your lawn a good soaking and allowing time between waterings encourages roots to grow deeper as they seek out moisture. A robust root system allows your grass to stay greener longer and it will require less water over time.
When To Water Your Lawn
Before you even think about hitting the grass with a steady spray of water, youll want to make sure you know the best time of day to do it. Although many folks assume night time is best, most experts will tell you thats a myth.
There are a lot of people who are surprised to find out that watering your lawn at the wrong time of day can have such an impact, says Botts. Watering at night often means that water will sit on your grass overnight, which can lead to disease.
Another no-no? Watering in the hottest part of the day. Although you may think your thirsty lawn wants a drink midday, the heat will cause evaporation to happen quickly, before water has had a chance to reach the roots of your grass.
The best time of day to water is in the morning, if possible some time between 4 a.m. and 10 a.m., Botts says.

Leave Your Clippings In Place
Some people remove their grass clippings because it makes the lawn look cleaner. This isnt the best thing for your yard if you want to keep it healthy. Why? Your clippings will break down and provide nutrients for the soil and plants.
Some people like to mulch instead of doing this, but its really up to you. Just make sure youre not removing and tossing clippings and leaves. Your lawn and plants need them, and your city would prefer to keep these items out of a landfill!
What Happens If My Lawn Gets Too Much Water
Too much water can damage your lawn, or even your homes foundation. Grass cannot grow properly in areas with standing water or spongy soil, which allows moss to develop. You may choose to re-grade your yard, amend heavy clay soil with organic matter to improve drainage, or install a rain garden or mulch bed in low spots that frequently fill with standing water.

There are tons of ways to water your lawn, from sprinklers to smart watering solutions. Each has their own sets of benefits, so choose the solution that works best for you and your lawn. Below are a few methods to consider.
Pulsating sprinklers : These shoot water horizontally at a high velocity so the water isnt affected by wind.
Hose-end sprinklers: Great for small- to medium-size lawns. There are many different types, so you can choose the one that fits your lawn best.
In-ground sprinklers: These can deliver water in the most efficient pattern. Choose sprinklers that are low to the ground and use a horizontal spray pattern for best results.
Conserve When You Can
Both for the health of your lawn, and your water bill, weve got some on how to conserve water when watering your lawn. Keep automatic sprinkler systems maintained and properly set. A broken sprinkler head that shoots a stream of water into the street doesnt do anyone any good, nor does one that runs during a rainstorm. Additionally, trees can be damaged from lawn watering that leaves their trunks wet over time or does not allow their roots to stretch out and grow between waterings.

Select A Sprinkler That Best Fits Your Needs
Automatic irrigation systems with pop-up sprinklers are often associated with excessive irrigation. However, properly designed and operated systems supply water uniformly over an entire area without wasted runoff.
Missouri soils generally have low water-infiltration rates. Automatic controllers can be set to supply several short cycles so that the total amount of water desired is supplied without runoff.
The most common type of watering occurs with hose-end sprinklers. Some studies have shown that the average homeowner applies 2-1/2 times the amount of water required for overgrowth when using hose-end sprinklers.
Several types of hose-end sprinklers are available . Select one that best fits the size and shape of your lawn, and operate it efficiently. All hose-end sprinklers can be attached to inexpensive timers that can be used to shut off unattended sprinklers and avoid overwatering.

Ignoring Your Grass Needs
Taking a lawns age into consideration is important. A fully-grown lawn can handle a more powerful spray, whereas newly seeded lawns need a gentler touch. If you only have a small area of newly planted seeds, a Stationary Square Sprinkler works well for gentle spot-watering, while an Adjustable Length Wind-Resistant Rectangular Sprinkler can cover a bigger area.
For a sprinkler that will grow along with the grass, try the Circular Sprinkler Spike with on/off switch. The diffuser pin allows for a customized force of spray, from a steady shower for new grass to a more powerful stream for mature lawns.

Considering The Role Of Salt In Soil And Water
In areas of the state where water is high in salts, plant a salt-tolerant grass species, such as Seashore Paspalum, bermudagrass, or Zoysia. Water deeply but only occasionally so salt does not accumulate in the soil. High levels of sodium damage soil quality and affect the ability of water to filter through the soil. Also, salt can exacerbate the effect of drought on turfgrass. Contact your county Extension agent for more information.

When Should I Water My Lawn
Timing is actually pretty essential when it comes to how to water your lawn. You want to focus on early morning watering — think pre-dawn or dawn. Why? This helps prevent evapotranspiration, which means youre losing less water to the intense sun that comes mid-day. This also saves you money on watering because each drop of water is maximized. You want to avoid watering at night because it can cause extensive disease pressure on the lawn. The combination of heat and humidity mixed with water can enhance the potential for pressure from diseases such as brown patch, dollar spot, and others.

Tips On Watering A New Lawn
Have you ever planted a new lawn only to be disappointed in how it grew in? Watering a new lawn is very different from watering grass in an established lawn. Many lawns are lost at the initial watering stage. The seed will live or die depending on how you water them.
So whether you have planted seed or laid sod, lawn irrigation must be done properly for best results.
Watering a New Lawn from Seed
For the seeds to germinate, the soil needs to be consistently moist and soil temperatures must be in the right range. Germination times vary with different species, but most lawn seed will germinate within 3 to 21 days.
When watering a new lawn, the best way of keeping the seed moist is by lightly sprinkling the seeded area of the lawn at least two to three times a day. Care must be taken to ensure the soil doesn’t dry out. The seeds could perish if they are allowed to dry once the germination process has begun.
Your lawn may require more frequent watering depending on the soil type, weather, temperature, or wind. Sandy soils retain less water than loamy or clay soils. It often helps to plan seeding before several days of light rain. But don’t rely completely on the rain. Be sure to monitor it well. If the seed dries out it may be too late to save it. Covering the seed slightly with soil helps tremendously in keeping it moist.
Remember, the best time for planting cool season grasses is in the fall and warm season grasses are best planted in the spring.

When To Water The Lawn
If you find your lawn has taken on a grayish cast or appears to be dull green, its telling you that it needs water. You can also check your lawn by walking on it: If your footprints dont disappear quickly, its because the grass blades dont have the needed moisture to spring back. While it may seem like you can head out to water your lawn anytime during the day, your lawn actually needs more specific care. Watering in the morning is the best time for your lawn its cooler and winds tend to be calmer so water can soak into the soil and be absorbed by the grass roots before it can evaporate. If you must water in the evening, try between 4 and 6 p.m. which should give the grass blades time to dry before nightfall. The later you water, the greater chance of disease becoming prevalent in your lawn. Its worth noting, though, that you dont necessarily have to water your lawn. Lawns are resilient. Established and properly cared-for lawns can survive weeks without water by going dormant , then recover once the rain returns.
Misconception #: The Best Time To Water My Lawn Is After The Sun Sets
While weve heard a lot of people in the Lehigh Valley or Buxmont, PA area say its best to water at night, the reverse is actually true.
The ideal time to water your lawn is just after the sun rises. At this time of day, its still cool and the water wont evaporate quicklybut it still gives the grass blades plenty of time to dry before the sun sets.
Wet, dark conditions create an ideal breeding ground for causing lawn disease that can damage your turf, so watering the lawn in the evening should be avoided.
If you cant find the time to water your lawn in the early morning, even with automated timers, then try to do it early enough during the day to allow grass blades to dry by nightfall. Mid-day watering wont hurt your lawn but you may need to do it longer as youll lose moisture to evaporation.
