Proper lawn watering techniques and knowing when and how much to water will assure a healthy, aerated lawn.
There are many signs that tell you that you have to water the lawn like bluish-gray color of the grass, wilted, rolled and folded grass blades etc. Also, you can dig a small hole 3 inches deep and if the soil is moist, you don’t need to water the lawn.rclma
Usually, a lawn requires 1 inch of water per week. In the case of bluegrass, it needs 1/2 inch. To determine the amount of water delivered by a sprinkler system. Place 5-10 small cans in the path of the sprinklers and turn the system on for 15 minutes. After the watering is done, measure the depth of the water in each container and divide it by the number of the containers. Multiply the amount by 4 to get the amount of water per hour delivered.
You need to detach the lawn when it is 1/2 inch thick as it increases the runoff chance of water, preventing for entering the soil. Thatch buildups can be avoided through watering, mowing and fertilizing.
You need to water the lawn in the morning when the grass is covered with dew. Watering in midday increases the chance of water evaporation while watering in the evening, doesn’t allow the lawn to dry and so increases the chance of disease to occur.
Aerating is very important to provide a proper water infiltration in the soil. Especially in clay soil, you must use a spading fork to loosen the soil and aerate it. For large areas use a power tool. The holes in the soil will reduce water runoff.
