At dusk in September the field edges around Ringgold go the color of dry hay, and something small is always moving along the fence line. Fox Trot Lawn & Landscaping takes the wide properties as readily as the tight ones — mowing, trimming, edging, and shaping the beds and shrubs that hold a yard together. Autumn is the season for cutting back and laying mulch so winter has less to take away. The line where mown grass meets rough field is the part they take care with; it is the line that tells you somebody was here. Fall light only makes it look better.
