The Ipswich River runs the north edge of town, and by mid-October the woods along it go copper and then bare in the space of two weeks. JO Lawn Care Services moves with that calendar in Hamilton — leaf cleanups, final cuts, beds cleared and cut back ahead of the freeze. Earlier in the year it is mowing on a weekly line, trimming, edging, and mulch where a border has thinned out. A lawn raked out clean in November comes back easier in May. It is satisfying work to finish in the cold.
