Some homeowners believe that watering grass simply implies switching on your sprinklers and let them run. But the actual truth is that these homeowners don’t realize that they may be overwatering or under watering their grass, which can have consequences. It is; therefore, essential to hydrate your grass with the right amount and at the right time. In this detailed guide, we will explain how to irrigate your lawn the right way.

Irrigating Timings and Types of Grass

When you are aware of the type of grass you have on your lawn, you will be able to understand the timings for irrigation.

Warm Season Grass

Warm season grass is more used to the heat in the southern parts. Thus, they grow and flourish more during hot summer months where temperatures fall between 80 to 95 degrees Fahrenheit.

Cool Season Grass

Cool season grass is adapted to cooler climates and can stay green and fresh until the temperatures drop below 32 degrees Fahrenheit. Cool season grass can easily survive subfreezing temperatures.

Lawn Irrigation Tips

Some lawns may require watering every once four to eight days to grow. This results in deeper rooted, healthier, greener plants, trees, flowers, and shrubs. But you must watch out for rain. If it rains often in your area, you should not water your lawn more than once a week. You can test when your grass needs water by walking over it. It should lightly spring back up when you walk over the grass. If it doesn’t, you will have to irrigate.

Try watering your lawn early in the morning as it is the best time for grass to absorb water all the way down to its roots. This also allows them to endure heat throughout the day since water can evaporate quickly. Although late afternoon can also be a good time to water the lawn, it is always best to do it as early as possible.

You should start preparing your lawn for the upcoming winter during fall. So, water throughout the month of September and once again in October to stock sufficient moisture in the grass.

While watering your grass, you must be cautious of the quantity. Your goal should be to moisten the soil deep enough to reach the roots. If you have clay-based soil, you will need to apply approximately 1-inch of water. In the case of sand soil, you should reduce the amount to 1/2 inch.

As part of your usual routine, keep an eye out for signs of over-watering. If you notice any pool or puddles of water, you overwatered your lawn. Overwatering can cause the fertilizer and other essential nutrients to wash away, which can have negative effects on surrounding trees and plants. Overwatering also prevents grass roots from growing, making the grass look dull and dry.

If you notice your grass turning brown or yellow during hot summer days, don’t panic. Many cool season kinds of grass shift to dormant mode even during summer days. You will start seeing fresh, green grass eventually after watering and when the temperature cools down. If; however, your grass does not revive, you will have to get it replaced.

Types of Sprinkler Systems

Traveling Sprinkler

Traveling sprinklers are supported by wheels that allow them to move around the lawn with a hose dragging behind. These sprinklers are great for lawns that have irregular shapes.

Impact Sprinklers

An impact sprinkler is also called a pulsating or impulse sprinkler. It comes with a spraying nozzle that rotates with the pressure of water. It comes in both brass and plastic. Although brass impact sprinklers are more expensive, they are highly durable. You can find impact sprinklers that can be attached to the ground or be slightly elevated (like a tripod).

Hose-End Spray Nozzles

Hose-end spray nozzles are versatile, easy to use, and affordable. They are also made of brass or plastic and come with a supporting handle at the end that is used to control the nozzle. You can control the volume of water by turning the nozzle.

Oscillating Sprinklers

An oscillator sprinkler has a plastic or metal bar with holes. The bar moves back and forth as water comes out of the sprinkler and waters the lawn. You can control the volume and size by adjusting the faucet. It is ideal for rectangular lawns.

In-Ground Water Sprinkler

An in-ground sprinkler has a series of different sprinkler heads set up at different locations on the lawn. In-ground systems provide efficient coverage if maintained and installed properly. There are various types of sprinkler heads available to choose from.

Gear Drive Sprinkler

This type of sprinkler is heavier compared to the rest and can usually be seen on golf courses where precision and a large volume of water are required. This particular sprinkler has several controls for flow that allow you to adjust the distance when the water is sprayed. You can also control the force and angle of the spray.

Fixed Sprinkler

A fixed sprinkler is inexpensive and simple. It consists of tiny holes and comes in a plastic or metal frame with a watering hose at the end. The lawn is sprayed with the water pressure that comes from the small holes. The pattern of holes on the sprinkler determines the pattern of spraying and the volume of water can be controlled using the faucet at the end. You can also drag it around the lawn to change the area.


Watering or irrigating your lawn properly is crucial to maintaining healthy trees, grass, flower beds, and shrubs. You will be able to maintain a beautiful lawn by following these essential lawn care tips.
