Morning in Hudson arrives off the Merrimack — river fog lifting past the Taylor Falls bridge, thinning through the pines until the lawns on the east bank come up bright and wet. Tamarack Landscaping works in that light, mowing clean lines across yards hemmed by old stone wall and second-growth woods, trimming and edging until the grass holds an even shape from the first warm week clear through August. Then the ground goes hard and quiet, and the plowing starts long before the streets wake: driveways off Lowell Road opened down to pavement, walkways cut wide enough to carry a person out to a warm car. It is honest, physical work with a result you can see from the road — a yard that keeps its season, a drive that is simply clear when the door swings open.
