The bluffs above Milford go warm-colored in September, and the light comes across the Delaware at a low, generous angle late in the day. Muller Lawn and Outdoor Services LLC is usually finishing a lawn about then — the last passes, the trimmer around a stone step, the blower clearing the drive. Through the year the work is mowing on schedule, edging, and the seasonal cleanups that take a yard from the final frost to the first. Autumn here means leaves in real volume, off the grass and off the walks before the rain glues them down. A yard cleared out in October is a yard that comes back green in April.
