Ridge, dale, then ridge again — the land around Hillsdale folds into shallow valleys, and you feel it in a driveway that runs downhill and a backyard that drains slow. Tri Valley Landscaping, Inc. works with that shape, mowing and trimming to the grade, edging where lawn meets pavement, mulching the beds and clearing them out when the year turns. The warm months here run long and green, and the weekly visit is what keeps a property from ever looking overgrown. Cold months rewrite the route entirely: driveways and lots plowed, walkways shoveled, salt on the pitched spots that ice up first. The same yards twice over, and both times the aim is a place that looks cared for by morning.
