August downtown, off Legion Parkway, the heat lifts straight off the brick and every patch of green in Brockton earns its keep. S & R Lawn Care Service mows, edges and trims through it, keeping beds mulched and lines crisp on properties large and small. Late-summer grass wants height and a sharp blade more than anything else, and the difference shows up by the following week. Spring and fall cleanups bracket the year, carrying off what the wind and the maples deliver. The measure of the work is simple: grass even, edges true, the walk swept behind you.
