Marblehead's Old Town was laid out by footpaths and stubbornness, so the lawns here are small, walled, and full of character — a patch of green between granite steps, a strip of grass running down to a gate. Somerby Landscaping works at exactly that scale, where a mower has to fit and every edge is visible from the sidewalk. Salt air off the harbor and thin soil over the ledge make Marblehead grass its own project, especially in the bright stretch of August when the hydrangeas go their improbable blue. Mowing, trimming, feeding, and seasonal cleanups keep those pockets looking looked-after, from Redd's Pond down toward the water. Small yards, done exactly right, are what give a street like this its composure.
