High noon in July, planes letting down toward Midway a few miles east, heat shimmering off the flat roofs — Stickney in the middle of summer asks a lot of a lawn. Noe Ramirez Landscaping Service Inc. answers with steady mowing at the right height, trimming into every corner, edging along walks and drives, and shrub work that keeps a house visible from the street. Cut too short in this heat and the turf gives up; cut on rhythm and it holds green well into September. The crew finishes with a clean blow-down, because clippings on hot concrete are the difference between done and nearly done. A small distinction, but it is the one people notice.
