If your grass is dead, watering it will not bring it back. You need to reseed your lawn or prepare it for sod installation instead. MetroGreenscape’s lawn care services can help with both these tasks. However, it’s possible your grass isn’t actually dead. During dry periods, grass may turn brown but not be dead. If it’s been less than six weeks since your grass turned brown, you can try watering it and the moisture may stimulate the live roots to start growing new grass.
