By September the crepe myrtles along Clinton's streets have thrown most of their color down onto the grass, and the light comes in low and copper by six o'clock. Premier Outdoor Services keeps yards through that stretch — mowing while growth is still steady, trimming the fence lines, edging the walks and clearing what has fallen. The Jackson Prairie soil under this town holds water hard and grows a thick lawn when it is tended. Shrubs get shaped for the cool months and beds get pulled back to a clean line. Come the first cool front, a yard kept this way looks like fall was planned for.
