There is a week in late April when Roxbury's cul-de-sacs all turn green at once and every lawn on the circle is suddenly being looked at next to the others. Neighbor's Envy Landscaping leans into that — mowing, edging, trimming, mulching and seasonal cleanups that make a front yard read sharp from the street. When the year turns, the same properties get snow plowing, shoveled walks and salted steps, so the driveway is clear before the buses run. Township winters up here deliver more than the towns down in the valley, and homeowners feel every inch of it. Between the two ends, the work covers the whole calendar, one street at a time.
