September light comes in low across the ballfields at Hamilton Park, and the grass finally slows down enough to show what it has been given all summer. Dr Green Lawns LLC spends its year on that green — mowing on schedule, trimming close where a mower cannot reach, edging walks and drives, and clearing the leaves once the oaks let go. Waterbury soil is old and stony and its yards run uphill, so a lawn here is coaxed rather than commanded. The satisfaction is entirely in the after: stripes running true, borders held, a yard that looks cared for from the sidewalk. Lawn care for Waterbury, one property at a time.
