There's a week in late October when the Naugatuck Valley can't make up its mind — mowers still humming on Ansonia's hill streets in the afternoon, frost waiting at the low end of the yard by morning. JJBM Landscaping & Tree Removal works right through that hinge, trading deck height for plow blade as the light goes short over the brick mills along the river. Green months are the clean sweep of a fresh cut and an edge held tight to the sidewalk, the dead limb brought down before it comes down on its own; white months are a driveway opened wide and dark before anyone in the house has stirred. Ansonia is a town of steep drives and stubborn maples, and this is work that leaves its proof out front where the whole street can see it.
