Drive the winding park road through D.W. Field on a June morning and you will see what Brockton grass can do when somebody pays attention to it. Alexander Laines's Landscaping tends yards across the city with regular mowing, clean edges along drives and walks, trimming, and beds turned over and mulched. Brockton's lots run narrow and its hills run steep, so the work becomes a matter of angles and patience. Spring and fall cleanups clear what the big maples drop at either end of the season. Nothing dramatic, just a yard that greets the sidewalk well.
