Morning in Dennis arrives twice — first as gray sea fog easing up off Nantucket Sound, then again an hour later when it lifts clear of the marsh grass and the whole town turns gold. Pessini Landscaping Inc. works in that light, building landscapes from the ground up and then keeping them: landscape construction, landscape maintenance, irrigation systems, and fertilization across the sandy, wind-combed soil of Cape Cod. It is exacting ground to plant in — salt riding the breeze, pitch pine and scrub oak leaning wherever the weather tells them to — so a lawn that comes in thick and holds its shape out here has genuinely been earned. Then the year swings around, a nor'easter stacks up against the bay side, and the same work becomes snow removal, driveways opened while the light over 6A is still the color of pewter. The pleasure of it is plain: an irrigation line laid true, a bed edged crisp against the sand, a yard that carries its season all the way through.
