The Bartlett Mall holds its green all summer, the frog pond flat below the slope, and the Rail Trail carries people past a hundred front yards on their way toward the water. Newburyport Turf Company works those yards — mowing on a set rhythm, trimming tight to trees and fence lines, edging drives and walks so the turf stops exactly where it should. Spring cleanups get the sand and winter litter off the grass; fall cleanups clear the leaves before frost mats them into it. Cut lines run straight and the color evens out as the weeks go on. A lawn like that reads well from the street, from the porch, and from underfoot.
