Now that your lawn has been planted, watering becomes the most important part of the job. Watering is so important that it can make the difference between luxuriant success and total failure.
Failures further delay the look of a beautiful lawn and translate into even more watering.
Therefore, successful germination depends on ample moisture at the soil surface. Soil can dry out very quickly on sunny or windy days. So during the first few weeks of watering, you need to concentrate on keeping the lawn surface moist. This is best accomplished by frequent light waterings, especially on hot, sunny days. Areas of the lawn in full sun need watered more often than partially shaded areas.
