I had that same problem a 2 years ago and no matter what watering and fertilizer i put in it..it still is dying. A neighbor who has beautiful lawn every single day of the year and never had any lawn service come to his grass told me that I have to start putting Lime on my Lawn quarterly every year.. So i did that, put lime on my lawn and water it, after 1 week i followed it it with Scotts fertilizer or any fertilizer for that matter since all are nitrogen base. And viola after just 1 to 2 months my lawn is dark green and holding its color even though I just water it once a week. There is no harm in trying this. I just want to share my experience with my lawn.
