Factors That Determine the Irrigation Schedule

Soil type – Clay soil allows for more flexibility in watering frequency compared to soil that has sand in its mixture.

Clay and loamy soil types (soil that’s composed of sand, silt, and a smaller amount of clay) retain moisture for longer periods, whereas sandy soils allow water to seep through quicker.

Humidity – If you live in a humid region, then new grass seed will require less water than in drier regions.

Variety of grass – While different grasses need different quantities of water, all grass seeds require roughly the same amount of water.

Before planting new grass seed (overseeding), make sure that get the first six to eight inches of soil moist. For a few days before planting, keep the lawn areas moist but not soggy.

After planting the grass seedlings, keep the soil moist by gently watering them for five to ten minutes.

Grass seed needs more water than mature grass, so it’s important to not let the soil dry out. If it dries out, the seeds can die.

Seed germination takes 5 to 30 days, depending on the grass variety and the weather conditions of your area.

Watering frequency will depend on the region you live in; but, on average, new seed should be watered twice daily.

How Much Water Does New Grass Seed Need?

The watering amount will depend on the sunlight, temperature, and humidity in your area.

Assuming your lawn receives five to six hours of direct sunlight with a temperature range of 50 to 75 degrees Fahrenheit (10 to 25 degrees Celsius), you should keep three to four inches of soil moist immediately after planting the seed.

Set a timer for five to ten minutes in your lawn sprinklers, once in the morning and once in the evening.

After one week, reduce the watering to once a day. Note that not providing enough water can attract birds to attack your new seeds.

After the germination process and the lawns have grown to be one inch long, you can reduce watering your lawn to once a day and only in the morning before 10 a.m. 

Lastly, try to avoid watering your lawn at night. There are many issues that arise when the water is left sitting in the soil and is unable to evaporate or get absorbed by the grass and grass seeds.
