Answer: Based on your description I am not certain what is happening to your lawn. Excessive browning can be caused by overfertilization or chemical burn, accidental herbicide exposure, lack of water, poor or unusual soil conditions, or a pest or disease problem. I would strongly suggest you work with your state extension service to try to determine what is happening. Based on knowing that, you can figure out how to repair it. There is contact information at their web site including an 800 number to call at
All the best with your lawn problem!
