Salem Street runs past stone walls that have been holding their line longer than anyone can properly say, and October drops half a maple across every one of them. Gagnon Landscape Contracting handles that fall stretch: leaves cleared, beds cut back, lawns given their last passes and an overseeding to carry them through to spring. Through the summer it is mowing, string trimming, edging and mulch on a rhythm you could set a week by. When the cold comes, plowing and walkway clearing take over, with de-icer laid down where the plow leaves a skim behind. There is a real satisfaction in walking away from a property that looks finished, whichever month it happens to be.
