The Holyoke Range lies along Amherst's southern edge like a low green wall, and in July the heat pools in the fields beneath it. A to Z Lawn Care keeps up with everything that grows in that heat — mowing, trimming, edging, bed upkeep, and the cleanups that open a yard in spring and close it in fall. Grass in the valley can put on a week of growth in three days after a thunderstorm, so the schedule matters as much as the machine. Edges cut true along a walk make even a plain lawn look composed. By evening, when the range goes violet, a finished yard has a stillness to it that is worth the day's sweat.
