A summer squall can cross Walden Avenue in twenty minutes and leave the grass an inch taller behind it. Green Lawn Landscapes keeps pace with that: mowing on a set week, trimming and edging so the borders stay crisp, cleanups after the wind takes the maples apart. Then the year turns and the very same properties need plowing, shoveled walks and salt at the door, sometimes twice before daylight. Lancaster asks both things of anyone who works outdoors here, and doing both means never handing a place off to somebody else halfway through. Green in July, clear in January, one set of hands the whole way through.
