Best Time to Run Sprinklers

Time to Run Sprinklers

Maintaining a healthy lawn requires taking care of your turf. This means making sure that the grass is regularly trimmed, the soil is free from weeds, and that the area received enough water. But let’s be honest – doing all these will take a lot of time and not all of us have the luxury of time.

Fortunately, modern technology has made doing chores less mundane and less time-consuming. One of today’s most useful inventions includes the sprinkler system, which reduces the need to manually hose down your lawn.

While the traditional sprinklers require you to turn the water manually, newer models can be set to turn on automatically at a given time. You can also set how long the water will be sprayed across your lawn, so you’re sure that the soil and the grass are never parched.

If you’re new to sprinkler systems, you might be wondering what is the best time to run sprinklers. We’ll answer that question in this article, along with other pointers that you should consider when setting up your sprinklers system. Here is a detailed list of the sprinkler system parts.

Preliminary Considerations

Before going into answering the question, there are some preliminary considerations that we all must look into. You must first determine how much water your lawn needs, and how you’ll be able to tell if it’s getting enough water.

When it comes to determining how much water your lawn needs, you have to do your research and look into the water requirement for each flora on your lawn.

Bear in mind that some plants are low-maintenance, and these plants may not need as much water as others. Conversely, some plants require more water to survive. Thus, you should check the water requirement for each plant first before you decide the time to run your sprinklers and for how long you’re going to let it run.

Once you determine the amount of water your lawn needs, you can now look for a way to determine if it gets what it needs. For this purpose, we highly recommend getting a rain gauge and installing it where it is exposed to rainwater and water from your sprinklers.

The reason for this is because your lawn will not always rely on your sprinklers for water. If it rains, there is a chance that your lawn will already get enough water, so having to run your sprinkler pump might be too much.

Thus, these are important considerations that you have to look into before determining when to run your sprinklers.

What is the Best Time to Run Sprinklers?

With that out of the way, we can now answer this question.

Experts agree that the best time to run sprinklers is around sunrise. This means that you can choose to run your sprinklers a few minutes before or after sunrise.

If you don’t believe it, there are two reasons why this is dubbed as the best time for your sprinklers to run.

First of all, there’s no denying that the temperature around that time is still cool, even during the summer months. There also seems to be a stillness in the breeze during this time. This means that minimal evaporation can take place so that the water being sprayed by your sprinkler gets absorbed by the soil. Thus, this is the best time if you don’t want to waste water.

And second, watering your lawn early in the morning allows the water to be absorbed by the soil within the day. This means that you don’t have to worry about your lawn is too wet.

Bear in mind that a lawn that’s been wet overnight can hamper the growth of your plans. Additionally, the moist soil can be a breeding ground for parasites and harmful fungi – and you certainly don’t want that in your backyard.


But while we can agree that the best time to run your sprinklers is in the early morning, bear in mind that this may not apply during the cooler winter seasons. Similarly, this may not also be the case if you live in a place where the climate is generally cooler.

During winter, early mornings are generally freezing, so watering your lawn at that time may not be the best idea. As a tip, observe and take note of the time when the soil seems to be absorbing more moisture. You can use this as your sprinkler time window to make sure that the soil gets the water it needs.

You can also observe the same tip if you’re living in an area where the climate is cooler. Usually, the sun is out at noon, so this may be the perfect time to turn your sprinklers on. You might want to read: Best sprinklers for long narrow lawn reviews and buyer’s guide.

Other Sprinkler Tips

Aside from determining the best time to run your sprinklers, you should also determine how long you have to run how, how often you have to water your plants and determine whether you’re already overwatering your turf.

All of these factors are equally important, otherwise, you might end up with a lawn with cracked soil or one with an overgrowth of fungi. Believe us, you don’t want either of those two.

Sprinkler Runtime

On average, running your sprinklers for about 20 to 30 minutes would already suffice. The length of time is usually determined by how hot it is outside because this can leave your soil dry.

During the harsh summer days, you may have to run your sprinklers longer to make sure that the water goes into the roots of the grass.

Sprinkler Frequency

As to how often you have to run your sprinklers, this would also depend on whether it rained on the days prior. With the help of your rain gauge, you can easily skip turning on your sprinklers if it appears that your lawn is well-watered.

On average, it is advised to water your turf for about 2 to 3 times per week. However, this number may change during the summer season.

Am I Overwatering?

By now, you already know the disadvantages of overwatering your lawn. Aside from killing your grass, it also makes the soil a fertile ground for the growth of fungi and other diseases.

To know if you’re overwatering your lawn, the first growth that you have to look out for are mushrooms. Mushrooms are the most common of fungi, so having them grow on your lawn should alert you.

If you notice a mushroom growing on your lawn, simply cut back on your watering amount and schedule, and the fungus will just die out and disappear.
