We all talk about over-watering but never really discuss how often grass should be watered in order to keep clients happy and the grass healthy. I realize that soils and temperatures along with the type of grass are all going to be variations in the timing and amounts. What I was curious about is whether there is a general rule of thumb that says how dry the soil should get before we turn the sprinkler on. I am specifically interested deep rooting the sod that was placed last year. It is in a good clay loam topsoil about 3 inches thick. Sod here is KBG.
