September mornings in Berwyn come with heavy dew, and the first cut of the day leaves a dark trail across a silver lawn. Omar C Eco-Friendly Lawns works those hours, mowing, edging, trimming, and handling the fall cleanups that follow once the parkway trees begin letting go. Grass in this town grows in small bright squares behind low hedges and iron fences, each one its own small responsibility. The finish is plain enough: a level cut, a sharp border, the clippings gone, the walk swept. It is a satisfying thing to leave behind, and it holds all week.
