April in Caldwell smells like wet clay and cut grass, and the ballfields at the Oval fill the moment the ground firms up. K Macken Landscaping LLC runs on that same calendar — mowing, trimming and edging from the first green through leaf-fall, then plowing and clearing walks once the drives go white. Both halves come down to the same two things, access and appearance: a lawn you would walk barefoot on, a driveway you can pull into at any hour. The tools change in November and change back in March. What happens in between stays the same.
