The Squamscott turns tidal below Stratham, and twice a day the marsh grass at Chapman's Landing lies flat and stands back up with the water. Bullfrog's Mowing & Landscaping LLC works the lawns above that river all through the growing season — mowing, trimming, edging, and cleanups at both ends of the year — then trades the deck for a plow when the weather turns. Seacoast storms come in wet and heavy, salt in the air and slush underneath, so driveways get opened early and walks get taken down to bare surface. There is a real pleasure in a lawn finished on a June evening, and a different one entirely in a drive cleared before the sun is up. The same properties, both halves of the calendar.
