The Salmon Falls River gave this town its water power and this business its name, and it still sets the weather — fog on the mornings, ice along the banks by January. Salmon Falls Nursery & Landscaping keeps Berwick yards on the beat the river keeps: mowing and trimming through the growing season, mulch laid in the beds, cleanups at the opening and closing of the year. Then the blade goes on, and it is plow work, shoveled walks and salt on the ice until the freeze finally lets go in March. Working the same properties around the whole calendar means knowing where the ground heaves and where the grass burns out in August. It is a good way to make a living in a town where the seasons are not subtle.
