Late in the summer the Hudson Valley hillsides go loud with goldenrod and milkweed and whatever else decided to grow there, and the line between a lawn and a meadow becomes a choice somebody has to make. Hudson Valley Native Landscaping makes it alongside the homeowner in Catskill: mowing and trimming on a set schedule, edging, mulch and bed work, cleanups when the season turns over. A lawn kept sharp against a wilder edge looks better than either one on its own. Most of the job is rhythm — same properties, same care, the grass even and the borders defined. In a valley this old and this green, tidy ground reads as attention paid.
