How frequently should a lawn be watered?

To keep your lawn healthy and looking good it needs water, proper watering is the key to a great lawn, not under watering or overwatering. It may sound strange but overwatering can be detrimental as fungus can quickly gain a foothold are ruin your grass. The amount of water that is delivered by sprinkling systems in Holland depends on three things; how much water does it take to hit the root zone, the weather and the type of grass.


Before attempting to figure out how often your lawn should be watered, you first have to determine how long it takes water to soak through the soil to the root zone. Depending on the grass the root zone can be anywhere from 6 to 12 inches below the surface. The time frame for the water to reach this depth also depends on the type of soil you have, the water will soak in slowly in clay whereas it will soak in quickly in sandy loam.

To determine the time it takes the water to hit the root zone, turn your sprinkling systems in Holland on for 15 minutes. After 15 minutes, turn the sprinklers off and wait a full 24 hours. After 24 hours dig a small hole and measure how deep the water has penetrated the soil. Divide the number 120 by the depth of the moist soil in inches. If you found that the water went four inches into the soil in 15 minutes, then 120 divided by 4 equals 30 minutes. To water a root zone at a depth of eight inches will take one hour.

Next, you must determine the amount of water your sprinklers are delivering within the hour. Set cans around the lawn and water the grass for one hour. After the hour has passed, measure the depth of water in the various cans. Once you have determined the length of time you must water and the amount of water the sprinklers deliver, you must water the same amount each time. The hotter the temperature, the more often you have to water, but the time and amount should remain constant.

Bluegrass needs about 0.25 to 0.33 inches of water per day in the summer. If the water in your cans averaged one inch, then you need to water every three to four days.
