In the northern reaches of San Diego, Los Peñasquitos Canyon carries its creek beneath sycamores and coast live oaks, and by March the late-winter rains have the canyon floor running green. Lawns across the city wake in that same season, growth quickening as the days lengthen and the soil stays damp. Wilson Woodscape Inc meets the surge with lawn care that keeps pace: steady mowing, neat margins along drives and paths, and trimming that frames a yard the way the canyon's trees frame the trail. Toward evening, when low sun slants gold through the eucalyptus and catches the newly cut grass, the whole property seems to stand a little straighter. It is a handsome thing, a lawn kept in step with spring.
