Any grass during the middle of summer (cool season types) needs massive amounts of water when summer hits to stay growing. In my area we had 2 months of non stop rain and then nothing the past few weeks.Guess what,those who aren't watering have brown lawns now even after all that rain in the late spring. The lawn needs consistent water,and with summer temps a stray t storm here or there does not cut it. What would happen if you drank a lot of water for a couple months and then didn't get hardly any for a few weeks? You would die too just like the lawn. If you look at Cinci's precip totals from June 26th on you have only received about .75 inches of rain.....a drop in the bucket and the equivalent of a 10 minute thunderstorm over 22 days.No lawn will survive that without watering. Either way to think you can wave a magic wand and green it up in a few days is just not possible no matter what you do or what product you use.
