By August the block is one long cicada note and the heat comes up off Hempstead Turnpike in sheets. GEO FLORES LANDSCAPING keeps a Salisbury summer schedule: mowing on the week, trimming close around fence posts and mailbox stones, edging the walks back to a straight line, hauling the clippings away. Late in the day the light goes gold and low, and a yard finished in that hour looks twice as good as it did at noon. Autumn brings the other half of the year — leaf cleanups, the last cuts, a lawn put away tidy ahead of the cold. Salisbury, Hempstead and the blocks in between stay on the route all season.
