Big oaks and maples line the older stretches of Old Somerville Road, generous with shade in July and generous with limbs after every storm. Jay's Yard Maintenance & Tree Service works the whole of that: tree trimming and removals, brush and limb cleanup, plus weekly mowing, string-trimming, edging, and the leaf work autumn demands. When the storms turn to snow, the trucks plow driveways and clear the walks and salt them down. There is a plain pleasure in handing a yard back open and orderly — canopy shaped, turf even, drive clear to the road. Hillsborough grows a great deal of tree, and all of it eventually comes down to the ground.
