In the North End the ground is mostly brick, which makes every green square in Boston feel deliberate — a courtyard, a strip beside a stair, a lawn tucked behind a wall. The Urban Gardener Landscape Service LLC looks after exactly those: mowing to the right height, trimming by hand where a machine will not fit, edging clean and carrying clippings out through a doorway. July sun bounces off the walls and dries turf fast, so feeding, overseeding and mulch earn their keep. Cleanups when the season opens and again when it closes keep the small spaces from vanishing under leaf litter. Grass in a city this dense is a choice, and it deserves to be kept well.
