Down by Marine Park the air carries salt off the marsh, and the grass grows differently for it, thick and quick and hungry all August. G&C Landscaping keeps those southern Brooklyn yards in shape with mowing on a schedule, edging along the walks, shrub trimming back from the fence line, and a full clearing once the maples let go in November. Wind off Jamaica Bay scatters everything twice, so the sweep at the end matters as much as the cut. A lawn that stays even across a whole block-long run of houses is something to be proud of. They work the season out to its last warm Saturday.
