Early June is the green hour of the whole year in Cimarron Hills — daylight stretched out to nearly nine at night, the lawns at full tilt, everything growing faster than anyone can keep up with. Greener Grass Lawn Care Inc keeps up with it: mowing on a rhythm, trimming fence lines and posts, edging the walks back to a straight line, hauling the trimmings away. There is a stretch in there when a yard can go from neat to shaggy in six days, and staying ahead of it is most of the job. The reward is simple and repeatable — pull up, work, pull away from a lawn that looks composed. Multiply that by a street and the whole neighborhood lifts.
