Grass under old oaks is its own problem. On the wooded bluffs above the Fox, light comes down in coins and moves all afternoon, and a lawn there grows slower, thinner, and far less forgiving of a careless cut. Black Creek Landscaping & Tree Services mows those shaded yards high and clean, keeps the trimming close around trunks and beds, and clears the leaf fall that would otherwise smother everything by November. There is a quiet reward in a shade lawn that holds together — soft, even, no bare rings, the beds edged crisply against it. That is the work offered to homes in Algonquin and the wooded towns nearby.
