July fog lifts off the South Branch of the Raritan before sunrise, and the valley hangs onto that humidity all day long. Pacheco's Landscaping starts in the cool of it — mowing, trimming, edging and mulch across Flemington and the river towns close by. Bottomland grass comes on fast and thick here; a week's delay is the difference between a cut and a harvest. There is quiet pride in stepping back from a finished yard with the blade marks still fresh and the walks blown clean. The heat can have the afternoon, because the good work is already behind you.
