St. Johns sits under an enormous sky — flat fields running to the horizon in every direction, wind crossing them all day, a grain elevator standing up like a landmark. Grassmaster Lawnscape LLC keeps the town's lawns in order under all that open weather: weekly mowing, string trimming, edging along walks and drives. Wind and sun dry a Clinton County yard fast in July, which makes cutting height and timing matter more than anything else. The payoff is turf that holds its color and a border you could follow with a straightedge. Big country, small precise work.
