The best time to water grass

Everybody wants a green, beautiful, healthy lawn and the best way to achieve this is with proper watering. Too much water can make your grass susceptible to disease, drown your plant’s roots, and keep the pores filled with water instead of oxygen, thus suffocating your grass. 

On the other hand, too little water can cause your grass to lose its rigidity in cells and ability to stay upright. Basically, both overwatering and underwatering will not help you get the green and healthy lawn you want. 

Any weed treatment or even the best fertilizer will not be effective if you are not watering your lawn properly. You might be asking, “when is the best time and how often should I water my lawn?” The  most important thing to keep in mind is that you must water your lawn deeply and less frequently.

Lawn watering tips

The best to water your lawn is early in the morning, before the temperature rises. The recommended time is between 6am10am. This is the perfect time to soak your lawn as the calm breeze and cooler temperature during this time helps the soil absorb more water and allow water to spread out. Watering in the middle of the day is essentially a waste of your time and water, since the sun is hot and rapid evaporation will just turn the water into gas even before the soil can even absorb it.

Watering in the evening can have negative effects as well. A lack of sunlight will leave you with a wet lawn overnight, which is the perfect condition for fungus to grow. You should also avoid watering when it is windy to lessen evaporation. Watering when it is windy only might just waste your water by This will essentially water your sidewalks instead of your lawn.

Watering your grass deeply will help the roots elongate and are able to absorb more nutrients, moisture, and oxygen. The rule of thumb is you need to water your lawn deeply by giving at least one to one and a half inches of water per week (including the rainfall, if any) to soak the ground sufficiently, depending on the type of grass. Lawns with sufficient moisture will develop deep root systems which help your grass to thrive and avoid vulnerability to drought, disease, weeds, and other issues.

You can do a “screwdriver test” to confirm that you are watering your lawn adequately. Just take a screwdriver and push it into the soil, if it goes 6 to 8 inches into the ground easily, then you have watered your lawn enough!

Watering frequency

You should water your lawn deeply two to three times a week. As mentioned above, your lawn needs 1 – 1 ½ inches of water per week. To measure the amount of time needed to get that amount of water, you can put an empty tuna can, around 1 inch tall, under your sprinkler and see how long it will take to get half an inch of water. This usually takes around 30 minutes. Watering 30 minutes, three times per week, means your lawn will get 1 ½ inches of water. You can also do 20 minutes, three times per week to get 1 inch of water per week. However, we recommend that you run the test to get the right amount of time needed depending on the type of irrigation system you have, type of soil, the elevation of your lawn and climate in your region. 

Always make sure that the whole lawn is getting equal amounts of water. Also keep in mind that you need to water more during extremely hot weather to keep your lawn hydrated.

Watering systems

In this modern day, we usually automate everything we do manually, and that applies to watering your lawn as well! Homeowners are now investing in irrigation or underground sprinkler systems to maintain their lawn. 

Impact sprinkler

It is recommended that you should use a pulsating (impact) sprinkler if you have a lawn with mature grass. It’s rotary head shoots water out in a pulsating action in a powerful water flow which produces a much harder spray of water. It is not good for a freshly-sown lawn as it can wash away the seeds. However, it is best to use in large areas as it can accurately distribute water when placed in an overlapping triangular pattern and has adjustable screws and paddles that break up the jet stream and disperses water.

Oscillating sprinkler

Alternatively, if you have a new lawn, you can use an oscillating sprinkler. This sprinkler delivers water in a rectangular pattern, and deposits most of the water near the sprinkler head.This allows the water to land more softly on the lawn for minimal impact on the seeds.

You can compare different types of sprinklers and select one that best fits the size and shape of your lawn. You can also probably install sprinklers by yourself by checking out videos online as a guide. You just need to make sure that you are aware where all gas lines, power lines and cable TV lines are and check the current water restrictions in your municipal area before you start to dig. Be sure to call your utility companies if you need help. It’s better to be safe than sorry. 

The golden rule

Always remember the golden rule when watering your lawn: water deeply and less frequently.

Watering deeply just means the water is able to soak at least eight inches below the soil surface and less frequently generally means do not water everyday. Water your lawn early in the morning, two to three times per week for the grass root system to develop. Follow these steps and you can expect to grow a long-lived green and healthy lawn!
