Fog sits in the Naugatuck Valley most summer mornings until the sun clears the ridge and burns it off the brick mill blocks along the river. That is when Better Lawns & Gardens gets moving in Ansonia — mowers off the trailer, the first pass laid down while the grass still holds dew. Ansonia is a city of small, hard-won yards: narrow strips beside three-deckers, terraced patches held up by fieldstone, a green square of front lawn that somebody's grandparents graded by hand. Each one gets mowed to the right height, trimmed close along the fence line, and edged so the sidewalk reads like a drawn line. Beds are mulched in spring and cleared of leaves in November, and the reward is a block on a valley hillside that looks, from the bottom of the street, entirely tended.
