 You know, everybody says, oh, well, I have an irrigation system. Well, it doesn't matter if it's still hot. It doesn't matter if it's wet or not. It's hot. And a cool season lawn, the fescue doesn't like the heat. So it shuts down. It doesn't want to grow. It turns a little brown until temperatures cool off, and then it'll start to grow again. The humidity also creates an issue.
