Portland sits on granite ledge, and every May the city's yards come back green over stone that never really warmed up. Savage Property Services LLC follows that year end to end — spring cleanups, mowing, trimming and edging through the warm months, leaf removal in the fall, and plowing, shoveling and salting through the cold. Shallow soil and hard winters ask a lot of a small city lawn, which is why steady, regular attention beats any single big effort. The satisfaction is in the before-and-after: a lot that was a mess at nine and looks square by noon. Yards and driveways get looked after in Portland, Westbrook, South Portland, Falmouth and Cumberland.
