I don't do fertilizing or problem diagnosis, I just mow for some older folks in town. I mow an older neighbor's lawn and it looked great the past couple of years. However, this year it looks really bad. He has an irrigation system that he runs early (4-5am start) every day. He and the house next door use the same fertilizing company (tru-Green/ChemLawn I think). The neighbor's yard looks good. The guy's I mow looks like it is dying, brown spots and dead grass everywhere. Can any of you offer any suggestions?
