The first mow of the year in Deer Park usually lands in a week when the ground has finally dried and the woods over toward Belmont Lake have gone from gray to that pale, new green. Superior Landscaping Services starts the season there — winter grit raked out, matted spots opened up, the lawn given its first honest cut and a clean edge along every walk. From then on it is a rhythm: the same yards, the same day of the week, the grass held at a height that can take a Suffolk County dry spell without going brown. Autumn closes the loop with the leaves cleared and the beds put in order before the cold sets. Watching a tired spring yard come back sharp is the best part of the job.
