Buttonwood Park's big trees throw a shade so deep the grass beneath grows in a different accent — thinner, slower, greener late into the year. GreenRoots LawnCare works with that instead of against it: mowing at the right height, trimming close to trunks and fences without scarring them, edging the walks until the line is unmistakable. Spring brings the cleanup that lifts matted leaves off the crowns; autumn brings the long haul of raking and carting away. In between there is nothing exotic, just a mower run true, week after week, across the west side of the city. Grass rewards attention more than ambition.
