Down University Boulevard in June the mowers are out by seven. Mow With The Flow Denver runs its Cherry Hills Village route on that beat — cut, edge, trim, blow clean, next. Stripes laid straight across an acre of bluegrass are worth the extra pass, and so is a border held to a real line rather than a rough guess. Fertilization, aeration and overseeding keep the stand dense enough to take the summer; weed control and seasonal cleanups keep everything else off it. Steady week to week, and the street shows it.
