Everything in this county starts underground — the beans, the beets, the wheat, and the front lawn just the same. Oswald's Fertilization brings that thinking into town lots in Sandusky, feeding turf on a seasonal schedule so it comes up thick in May and holds its color through the dry weeks of August. The proof shows up quietly: grass that fills in even instead of thinning at the edges, a yard that takes the heat without going straw-colored by the elevator's busy season. Mowing and general upkeep keep it looking the way the feeding intends. Sandusky and the farm towns around it are the ground it covers.
