How Long Should You Water Your Lawn With An Oscillating Sprinkler?

An oscillating sprinkler allows greater control over the water applied to each yard area. In addition, it helps prevent runoff because the water goes into the ground instead of out through the pipes, which allows you to maintain the green vibe on your lawn. But how long should you water your lawn with an oscillating sprinkler? We are gonna answer all of those questions here. Dig in to find out-

Oscillating Sprinklers: What are they

Oscillating Sprinklers

An oscillating sprinkler is a type of sprinkler that rotates back and forth like a pendulum. They work by spraying a fan-shaped curtain of water. These sprinklers are very efficient because they spray over a large area without moving the sprinkler head.

They do this by having metal arms oscillating backward and forwards, covering a wider area than stationary sprinklers.

These sprinklers spray a fan-shaped water curtain, usually about 4 feet wide. Over a large area, they provide even coverage. Oscillating sprinklers work well on smaller yards where you don’t want to move the sprinkler too much. On larger yards, however, they are less effective because the oscillation makes it hard to cover the whole yard evenly.

Large lawns are most commonly sprinkled with oscillating sprinklers when a large area needs to be covered quickly and efficiently. There are various types of sprinklers out there too. Just be sure to grab the best. Click here to know Ways to Divert Water Runoff Away from Your House.

Is There a Right Amount of Water for My Grass?

The proper amount of water varies depending on where you live and how much rain falls during the year. You can safely let your lawn dry out between watering sessions in areas with no hard freezes, such as Florida.

However, in colder climates, such as New England, you must keep your lawn well watered throughout the winter months. If you don’t, your lawn could die off entirely—also, the demandable amounts of water vary with grass type.

If you have an irrigation system, follow your manufacturer’s instructions for the best results. You might want to check your sprinkler heads periodically to ensure they aren’t clogged up. Also, make sure your sprinklers are set to deliver water evenly across your lawn.

Is it necessary to water my lawn every day?

Yes and no. I think three different ways to determine how much your lawn needs watering.

The first is to use a weather app like AccuWeather to see what the current conditions are in your area. Of course, you’ll want to ensure you’re getting enough rain during the summer, but you don’t want to overdo it. Too much water could lead to runoff problems.

The second method is to look up average rainfall amounts for your region. For example, here in North Carolina, we typically receive around 50 inches of rain annually.

So, looking at a 60-inch lawn, you might think twice about watering daily. However, if you’re looking closer at 30 inches, you’ll probably want to water every couple of days.

Finally, the third method involves sticking a soil testing kit into your lawn. This is the most accurate method because it gives you data on how much moisture your lawn contains. But, it requires some work. You’ll need to dig up a small portion of your lawn, take a sample, and send it to a lab to test.

How long should you water your lawn with an oscillating sprinkler?

Most people who water their lawns with an oscillating sprinkler run them for 30 minutes. This may not be the right amount of time to get the best results.

Oscillating sprinklers are great because they can be left running, and you don’t have to monitor them. The problem is that not all oscillating sprinklers work the same, so you may need to adjust how long each cycle lasts based on your particular model.

For example, if a few minutes doesn’t seem like enough time for water to soak into your lawn, try adding an extra 10 or 20 seconds onto the cycle next time.

Sunset magazine recommends that you water your lawn once a week for an hour to encourage the roots to grow deeply. You should give them between 1 and 2 inches of water each week if your oscillating sprinkler dispenses 1 inch of water in an hour, water per week your lawn for an hour.

If the grass looks too wet after a few minutes of watering with an oscillating sprinkler, cut back on how long each cycle runs by 10 or 20 seconds until things look good again.

Does its size depend on timing?

Yes, It depends on your lawn’s size and the soil’s quality.

If you have a small lawn dense with grass, you might need to water for just 15 minutes or so—the ideal time for smaller water droplets to penetrate deeper into the ground and reach roots, where they’re most needed.

However, if you have a bigger lawn (or one with more weeds), it can take up to an hour or two for large droplets to get there.

How often should you be watering?

If your soil is sandy or shallow, it may not absorb much water. So if your grass stays green despite long watering periods, that’s good. But if it turns brown even after several days without rain and then stays that way after a few light showers (or heavy rains), then additional work may be needed for those roots to grow deep enough into moist soil layers.

So, they can access water when needed most during dry spells like summer months when a drought affects even well-watered areas periodically due to unusually hot temperatures combined with low humidity levels which mean less evaporation from plants’ leaves – causing them harder than usual times finding enough moisture within reach before needing another session with their sprinkler systems again soon after finishing today’s watering cycle.

Can you leave your sprinkler on and leave?

You can leave the sprinkler on and go do other things while it waters your plants.

You’ll save time using an oscillating sprinkler over watering by hand; most people spend about 15 minutes per 1,000 square feet of lawn area.

You won’t get wet when watering with an oscillating sprinkler because you’re standing far from the water source.

Unlike other watering devices that need sunshine to work effectively, oscillating sprinklers can also be used in the rain.

Waterflow: How to Measure It?

The goal is to find the average water depth in the cans you’ve placed around the yard. This measurement doesn’t tell us much about the flow rate of the sprinkler itself, but it does give us information about the soil moisture level around the sprinkler head.

To start

  1. Measure the distance between the sprinkler head and the closest can.
  2. Add up those measurements and multiply them by 0.5 to determine the volume of water flowing into the soil.
  3. Divide that amount by the number of cans, and you’ll know the average depth of the surrounding soil.

Now, let’s say you want to increase the flow rate. You could simply adjust the nozzle size of your sprinkler system to ensure more water is coming out of it.

Or, you could place another can directly under the sprinkler head, increasing the pumping pressure of the water in order to push more water into the ground. Either way, you’re increasing the water falling onto the soil, leading to better drainage.

It is easier to understand if we use an example: A sprinkler was surrounded by five cans for 15 minutes, and the water ran. There were 1.5 inches of water in can #1. One inch was in can #2. 1.5 inches was in can #3.

1.5 inches was in can #4. A total of 5 inches of water (1.5+1+1.5+0.5+0.5) was added together. Divide that by five since there were five cans (5 inches/5 cans), so it’s 1 inch on average. Multiply it by four to get 4 inches per hour.

In this example, The average water flow of an oscillating sprinkler is 1 inch every 15 minutes, so 15 minutes is enough time to water an entire lawn with an oscillating sprinkler. Any longer would overwater the lawn.

So, if a moderate climate with little rain is used to water a lawn, it would only take 15 minutes and 30 seconds for it to water. But if there was half an inch of rain one week, it would only take 7 minutes and 30 seconds.

Frequently Asked Questions [FAQs]

1. How Much Water Should I Give My Grasses?

“Sunset” magazine recommends giving most grasses between one and two inches of water per week.

2. What are the benefits of an oscillating lawn sprinkler?

If you want your grass to grow and develop deep roots without wasting water, you can be more precise with your watering schedule.

3. What are the benefits of using less water?

Keeping your lawn healthy while reducing the amount of water you apply will save you money even if you are not in drought conditions.

4. What is the best time of day to water your lawn?

Your lawn would benefit from morning watering (before 10 a.m.) because the air is cooler and the winds are calmer, allowing water to soak into the soil and be used by the roots before evaporation occurs.

5. When should I stop watering my lawn?

If you receive 1 inch of rainwater per week, don’t water additional. If there is rain, decrease irrigation to offset the rain. Overwatering will increase bacterial growth, causing fungal diseases.


We hope you enjoyed learning how to water your lawn with an oscillating sprinkler. Then, use that information in the right way so that you can make a healthy lawn and beautiful lawn.
