The mower goes out first, deck humming a level line across the grass, and the hands follow after it — trimming hedges, pulling weeds, working bark mulch in around the beds until every border reads clean. Kady Landscape Inc. keeps lawns, yards, and grounds in order around Exeter, where the Squamscott slides past brick and the salt air pushes up the tidal river from Great Bay: weekly, bi-weekly, and custom mowing for homes, businesses, and condominiums, spring cleanups of leaves and flowers and new planting, and fall work that carries the maples away and leaves a yard breathing again. Out at the shore they rake the sand smooth, grading the beach and lifting off litter, stones, and old sea grass until it lies open and even underfoot. Come winter the plows are on the driveways, lots, and walkways before the town wakes, cutting the first clean lane through a coastal storm. Exeter, Stratham, Hampton and Hampton Beach, Portsmouth, Greenland, Newfields, Brentwood, Kingston, Seabrook, and down over the line to Amesbury and Newburyport — a stretch of Seacoast that holds its season.
