The Kaskaskia loops south of Vandalia through timber and bottom ground, and everything near it grows fast once June sets in. GM Enterprises LLC meets that growth with mowing on a steady rhythm, string trimming along foundations and fence posts, edging where turf wants to creep over the concrete, and a blower run that sends clippings back into the yard instead of the street. There is a particular hour in a Fayette County summer, late afternoon with the heat just beginning to let go, when a freshly cut lawn looks like it has been pressed flat and even. Cleanups bookend the season: thatch and old leaves out in spring, the last of the maple drop cleared in November. The aim is a yard that looks tended every single week, not only the week somebody notices.
