Its is essential to begin watering new turf grass sod within a half hour after it is installed or placed on the soil. Apply at least 1 in of water so that the soil beneath the turf is very wet. Ideally, soil 6 inches below the surface will be moist.
Water as early in the morning as possible to take advantage of the grass’s normal growing cycle. Morning is ideal because of lower wind speeds and less water is lost to evaporation. Watering in the evening is discouraged because water remaining on the grass can promote disease and fungus.
Infrequent and deep watering is preferred to frequent and shallow watering. Roots will only grow as deep as their most frequent available water supply. Deeply rooted grass has a larger “soil-water bank” to draw moisture from and this helps the grass survive drought conditions and hot weather that dries out the upper soil layer.

Water is essential to all life… too little water and we die, too much water and we drown. The same is true of the grass in our lawns. Water makes up 70% to 80% of the weight of grasses and the clippings alone are nearly 90% water. While most people are concerned about not watering their lawns enough, the fact is, more lawns are damaged by over watering.
