The ballfields at Oakton Park set a standard a front yard can borrow: even height, clean edges, no ragged corners anywhere. Marks Landscaping Service holds Skokie lawns to that measure, mowing on a regular turn, trimming around trees, posts and hydrants, cutting the edge back where turf has crept over the concrete, clearing hard surfaces after. Cleanups deal with the spring thatch and the autumn drop. It is repetitive work, and the repetition is exactly what shows. Come July, a lawn that has been on schedule looks nothing at all like a lawn that has not.
