The South Branch of the Raritan begins right here, in the marshland at the middle of Mount Olive, and everything green in this town gets going about when the river does. DiCambio Landscapers LLC opens the season with the spring cleanup — winter's debris hauled off, the beds cut back, that first mow which finally makes a lawn look like a lawn again. Through summer it is mowing, edging and trimming on a steady rotation, week after week, until the light goes short and low. Then the trucks change over and the plowing starts, driveways and walkways cleared so a Monday morning can happen on schedule. Same properties, same crew, two entirely different kinds of weather.
