Last year we decided to plant fescue seed in Sept. The grass grw in well and was thick and lush up until yesteray. It was about 87 deg F in the Atlanta area yesterday and my grass was looking brown and thin when I got home about 3pm. I immediately started to water it, and first thing this morning. I cut it at about 3.5 in or so to withstand the heat, but the way it's looking, I don't think it can stand the whole summer. Any suggestions? I water it about once a week for about 30min. It's only 2500sq ft.
