I have one mowing account in the neighborhood while I weigh the idea of getting further into lawn care. Taking it slow. This home owner has a fescue lawn. The yard was thick and green back in late May. Now the front yard has brown patches and grows very slow. The side yard (no backyard) is still green and thick with not one weed. This summer has been hot and dry except for the occasional afternoon t-storm. I cut it at the highest setting (about 4"). Did I do something or is this just the problem with fescue in the hot south? I can get pics later if that would help.
