Many homeowners who seed their lawn might have undesired results from improper watering. They might use either too much or too little. With correct watering, homeowners can nurture a well-established lawn. Proper watering begins even before you seed. Water the ground to be seeded with 4 to 6 inches of water for a better germination rate.
Schedule your watering in the morning. Less evaporation will occur, and it will help get the seeds and new seedlings well hydrated for daytime heat.
Cover the seeds with a layer of mulch, such as straw or lawn clippings to help reduce evaporation.
Water the seeds after the soil dries on top. According to the University of Wisconsin, newly seeded lawns can often be watered every other day; however in the summer or in warmer climates, daily or twice-a-day waterings might be necessary.
Avoid watering the seeds too much. Use about an inch of water so it can seep in during the watering. Use a sprinkler, but do not allow puddles to form.
Reduce the waterings once the grass reaches 2 inches in height. Begin to water about two to three times a week. Two weeks later, reduce again to once a week. One inch of water per week is usually sufficient for most established lawns to survive.
