Late August in Greene County browns the ridges and asks a great deal of a lawn — long dry stretches, then a thunderstorm off the mountains that pushes three inches of growth in a week. EverGreene Outdoor Services works with that swing, mowing at a height that shades its own roots and trimming and edging so the shape stays sharp even when the color fades. Wide open lawns get taken in long even lines; the tight corners get the string trimmer with a blower right behind it. Fall means leaves off and beds cleaned out; spring means mulch down and hedges cut back. Grass around Greeneville is worth that kind of attention, and it shows from the street.
