Late August on Peck's Road, the grass has gone slow and the light starts leaning toward evening a little earlier each week. Koldys Lawn Care works that whole arc across Pittsfield -- mowing on a regular schedule, trimming close along walls and fence lines, edging drives and walks, and clearing the cuttings before pulling out. A lawn that gets kept every week never has a bad week, and that is most of the secret. The Berkshires give about seven good growing months, and none of them should be spent catching up. What is left behind each visit is a yard that looks finished rather than merely mowed.
