Tenafly Road climbs out of Englewood at an easy grade, and every June the lawns along it grow faster than anyone can keep up with. That is the stretch of weeks Barron Landscaping and Hardscape LLC is built for: mowing on a steady rotation, edges cut back to the concrete, borders trimmed out, the season's cuttings hauled off. Grass on this side of Bergen County comes in thick after a wet spring, and holding it takes rhythm more than hurry. The result is a lawn that keeps its shape all the way to September — lines running true, nothing shaggy at the fence, nothing scalped at the corners. Summers here are short, and a good lawn should get to enjoy all of one.
