August in Lexington is sailboats crowding the harbor and lawns that have to look right for company. Northshores Landscape & Design tends the turf behind all of that — mowed on schedule, trimmed close around posts and beds, edged so the shape of a yard reads clearly from the street. Lake air keeps the grass going late here, and a fed, weeded lawn will hold its green well past the week the beach empties out. Spring brings the cleanup that hauls off whatever winter left; fall brings the leaves, and then the town goes quiet. What remains is a yard that looks composed — every line intentional, nothing shaggy in the corners.
