I recently killed off all my grass in my backyard and seed with K31. The K31 seemed to thrive all spring, but has completely died off when the tempratures hit the 90's. I watered it twice a week for 15 minutes at a time on weeks it didn't rain. I live 30 miles south of Atlanta and am wondering if tall fescue will work at all in my area. My backyard is shaded, but receives about five hours of direct sunlight per day. My front yard was sodded with emerald zoysia a few years back, but thinned out in lightly shaded areas of my yard. Will fescue, bermuda, or zoysia work best for me? My yard looks like crap and I don't want to invest in the wrong grass again.
