The Downriver spring arrives all at once — one warm week in April and every lawn in Trenton stands up demanding attention. Green Volt Landscaping LLC meets that surge with the first cuts of the year and spring cleanup, then weekly mowing, edging and trimming right through to the frost. Early morning is the hour for it, dew still sitting on the blades, the river flat and pewter a few blocks east. A lawn caught on the upswing keeps its shape all summer; one let go never quite catches back up. So the route starts early and stays on the schedule it set.
