Just put in about over 3000 sq yds of empire zoysia sod, and it looks great. Watering to keep moist now, but I hear that it will need mowing maybe as early as 7-10 days after taking root. Does this sound right? Also, can it be mowed the first time with a rider (ZTR)? Or should it be mowed with a walk-behind first since the rider may be too heavy? The prep for the soil didn't go too deep, but did include a little mix of topsoil to help grade, etc. Appreciate all thoughts.
