The land around Davison rolls in long glacial swells, and after a June rain the whole county turns a green so loud it almost hums. Greenscape of Davison L.L.C works right in the middle of that — mowing on a steady cycle, trimming the corners a mower can't reach, edging so every lawn ends in a clean line instead of a fray. The name says where home is, and the routes stay close to it, which means knowing which yards hold water at the bottom of the rise and which bake dry at the top. When the green goes, the plows go on, and the same driveways get opened after each Genesee County snowfall. One town, both seasons, ground that always looks in hand.
