Saturday afternoon in Arlington, and the side streets are all shade and hydrangeas. Screen doors bang. Somebody's radio drifts two porches down. Ever24Seven Landscaping LLC moves through that quiet with mower and trimmer, taking the small lots one at a time — cut, edge, blow the walk, move on — because the yards on these blocks are close enough that one tidy lawn lifts the whole row. Late in the season the work turns to clearing what the trees drop, so the turf goes into the cold with nothing sitting on top of it. It is unhurried work in a neighborhood that likes things kept up, and the proof is simply how the street looks by evening.
