October turns the marsh grass at Allens Pond to bronze, and the whole south end of Dartmouth smells of salt and cold leaves. Rapoza's Landscaping LLC is in the yards then with rakes and blowers, clearing the season off the lawn so the ground can breathe until spring. The rest of the year keeps a steady rhythm of mowing — weekly cuts, trimmed edges, crisp borders held against the beds. Every so often the wind swings around and you can hear the ocean from the driveway you are standing in. Good grass here is earned, and it looks it.
