West Denver in July is a dry heat that comes up off the pavement in sheets, and by four the north side of a Barnum bungalow is the only sane place to stand. Mark's Quality Lawn Care mows, trims and edges those west-side yards early, before the day turns mean. Bluegrass here wants a taller cut and a lighter hand than most people expect, and the difference shows up in August in who is green and who is straw. Spring and fall bring the cleanups, winter grit raked out and the last leaves gathered up. Ordinary work, done the way it ought to be done.
