The season opens with the pull of a cord and the level drone of a mower finding its line, blades set true across a Wallingford lawn until the grass lies down in even rows. VMA Landscaping Services LLC works the yards and drives of this old silver town in the Quinnipiac valley, where traprock ridges hold the late western light and the river bends past streets that still remember the mills. There is a plain satisfaction in the crisp edge along a walk, the trimmed border, the lawn that keeps its green through a long central-Connecticut summer. When winter shoulders down the valley, the same hands are out before the streetlights fade, pushing the snow back and clearing a path so the morning can begin. Lawn care in the warm months, snow removal in the cold — steady work that keeps the ground under Wallingford tended and open.
