Drive south out of Hamburg in October and the fields give way to orchard and vine, and the whole stretch of road smells like cider and wet leaves. That is the busiest run of the year for a lawn crew: leaves off the turf before they mat, beds cut back, the season's final mowing taken a little lower than the rest. The other months keep their own routine — weekly cutting, string trimming, crisp edges along walks and drives, mulch turned over in spring. Enser's works Hamburg lawns from the first green push of the year to the last cart of leaves hauled away. Then the ground rests, and so does everybody on it.
