Out toward the open space at the north end of Thornton, October comes in low and gold, the grass stops racing, and the ash and maple let go all at once — usually the same week the first wet snow tries to catch them still holding leaves. Viselac Lawn Service works that stretch of the year as carefully as the green of June: the last cuts taken a little shorter, the leaves gathered off the turf before they mat and smother it, the walks and the drive blown clean, the beds tidied for the cold. Then the yard sits neat under the first white, waiting. The rest of the season is the plain weekly rhythm — mow, trim, edge, clear — done on time. Lawn care for Thornton yards, from the first green haze in spring to the last bag of leaves.
