The Stonehocker farmhouse still stands in town, a plain reminder that these blocks were beet and hay ground long before anyone laid a lawn across them. MK Lawn Service & Landscaping LLC works that same dirt, only in quarter-acre pieces now — mowing, trimming, edging, fertilizing, aeration, shrub trimming and landscaping projects that give a yard some shape. Heavy clay and alkaline ground respond to aerating and feeding rather than to hoping, and the color shows it by the second season. The best part of the job is a lawn that looks handsome from the sidewalk and feels soft under a kid's bare feet. Northglenn, Thornton, Federal Heights and Welby.
