Mornings on Ashmere Lake begin under a mist that will not burn off until the sun clears the ridge, and up here the growing season arrives late and leaves early. JRD Mowing works inside that short bright window, cutting Hinsdale lawns from the first honest green in May straight through to the frosts. Hill-town yards run to slope and ledge, so the mowing is laid out in passes that read with the land instead of fighting it. Trimming and cleanup follow every cut, and the borders get tended before the goldenrod takes over the roadsides. In the Berkshires a kept lawn is a small act of optimism, and it looks like one.
