In July the only kind hour in Union City is the one before the sun clears the treeline, while the air is still cool enough to be worked in. Jovan Enterprises LLc takes that hour — mowers off the trailer early, cutting through the dew, edging drives and walks, trimming whatever the deck misses, and blowing the clippings back into the turf where they do some good. Heat builds fast off the asphalt on this side of the county, so the day gets planned backward from noon. Yards left neat before most people finish their coffee: that is the shape of a good morning. When the grass finally slows, seasonal cleanups fill in the calendar.
