By mid-July the lawns sloping down toward Swanzey Lake grow faster than anyone plans for — all that humid Cheshire County air, all that afternoon light coming off the water. Guyette's Sales & Service keeps them in hand with steady mowing, trimming and edging, the sort of routine that makes a yard look effortless. A cut line held straight along a flower bed is a small thing that changes how a whole property reads. Spring means waking the turf up after the sand and salt of a Swanzey winter; autumn means staying ahead of the leaves until the last oak lets go. The work is unglamorous, and it is exactly why the place looks the way it does in August.
