August in Harvard is long light and heat that hangs over the fields until nine at night, and the grass grows fastest in exactly the week nobody wants to be outdoors. Mercado Lawn Care Services is out in it regardless — mowing, trimming, edging, blowing the clippings off the drive so the cut looks as good from the street as it does from the porch. Spring and fall bring the bigger passes, the cleanups that take a yard down to bare, even turf. In the evening the grain elevator throws its long shadow across town, and the lawns underneath it are all in stripes. Lawn care in and around Harvard.
