Six o'clock on a June evening in Chiltonville, the Eel River winding through its meadow, and the day's heat finally letting go. That is when a freshly mowed lawn looks its best — the pattern still showing, the edge along the walk cut clean enough to run a finger down. South Shore Green Inc. keeps lawns on that standard around Plymouth, from houses on the old farm roads to the office frontage along the Route 3 corridor: regular cutting, edging, trimming, fertilizing, and the seasonal cleanups that bookend the growing year. Grass here grows fast in wet Junes and sulks in dry Augusts, so the schedule bends to the weather rather than the calendar. A lawn kept right all season is a quiet thing, and it is worth doing well.
