Mendon holds its light late in summer; the sun drops behind the ridge and the backyards stay blue and warm for another half hour. Lux Outdoor Living tends the ground people spend those evenings on — mowing in even passes, edging along paths and patios, keeping beds weeded and the mulch line neat where the lawn ends. Grass on this glacial ground grows unevenly, thick in the hollows and thin on the rises, so the cut has to be read rather than repeated. A spring opening and an autumn clearing bookend the year, leaves off before the ground locks up. A yard finished at dusk in Mendon is a good place to stand.
