Up on the north end, where the streets tilt toward the ridge, the ground drains fast and the lawns want a different hand than the flats do. Michael Bullis Lawns and Landscaping works those Hawthorne slopes — mowing across the grade, edging the walks, trimming the terraces and wall lines, feeding to hold thin soil together. Morning sun reaches that side of the borough first, and by nine the dew is off and the work can start. Cleanups in spring and autumn keep the beds from filling with everything that rolls downhill. A hillside lawn kept even is a quiet sort of accomplishment.
