Answer: Browning can be caused by many factors such as poor rooting, grading changes, varying soil moisture or uneven soil preparation, over or underfertilizing, or a pest or disease problem, or even problems such as dog urine. Without knowing the cause of the browning it is difficult to make a recommendation. If the sod is truly dead you will need to reseed or resod those areas. If the sod is alive but off color, then there may be steps you can take to restore it. I would suggest you work with your local county extension to determine the cause(s) of the off color and based on knowing that, work from there.
