Saturday morning in Emerson has a sound to it — mowers up and down the block, somebody's trimmer, a hose running over the Belgian block at the foot of a driveway. Vic's Landscape Contractors is part of that sound most weeks from April on. Cutting, trimming, edging, mulching the beds, hauling off the debris that piles up fast in a borough this shaded. July asks for the most: heat, growth, and a schedule that cannot slip. A clean-cut lawn at noon on a hot day is a small, complete thing, and it is worth doing right.
