I know it's not the best time of the year to plant new grass but I put in a new irrigation system and I planted on the trenches. The grass came up fine but now it has slowly started dying. I'm not sure if I am maybe watering too much or too little for the new grass or is just too hot this time of year in Atlanta for new grass. I planted Pennington Tall Fesue. The mature Fesue grass is growing and looking great. I'm watering 4 times a week early in the morning. BTW, I put the irrigation system in myself (with help of course), 7 zones, 62 heads and I love it. This site made it possible. Thanks for any advice/help.
