North of Seven Mile the streets stop running straight and start to curve, and the lawns of Palmer Woods sit under oaks that were tall before the boulevards were paved. NB Lawn and Landscape keeps that kind of yard in trim: mowing on a set schedule, cutting the bed lines back sharp, trimming close and hauling the debris away. On a July evening, when the light goes gold under all that canopy, a freshly cut lawn there looks like the whole street just exhaled. Landscape work is patient work — a little each week, until by August it reads as effortless. Care for the big shaded yards of the north side.
