By June the maples over Springside Park have closed their canopy, and every lawn in Pittsfield is growing faster than anyone can quite keep up with. Berklane Lawn & Landscape keeps that pace -- mowing on a steady rotation, trimming close along fences and foundations, edging until the line between grass and concrete is one clean stroke. Clippings get cleared off the walks rather than left in windrows across the drive. There is real pleasure in stepping back from a yard cut in even stripes with the smell of it still hanging in the warm air. Berkshire summers are short, and a lawn kept well makes them feel longer.
