Roselle's back yards are a private country: chain-link, tomato stakes, a grill, one good tree. Varela Landscaping works them as carefully as the front — mowing, trimming close along fences, edging beds and walks, and clearing whatever the season drops. September evenings here come with cicadas and the smell of somebody's dinner two doors down, and a yard that has just been cut fits right into all of it. The borough is dense, so the difference between a tidy lot and a rough one gets felt by four neighbors at once. Keeping the grass even and the corners clean is a small thing done often, and that is most of the job.
