Great Scott Landscaping works the rolling ground west of the Merrimack, where Bedford's lawns spill out from the road in long green aprons between stone walls and white pine. The work is lawn care, plain and honest: grass cut to an even nap, edges drawn clean along the walk and the drive, clippings gathered so the yard looks like somebody loves it. There is a real pleasure in the last pass of a Bedford afternoon, when the light comes in low over the hills and the mower lines lie across the slope like brushwork. Week after week that steadiness shows — a lawn standing up straight through July heat, still trim and tidy when the maples go copper along the old farm roads. Great Scott Landscaping keeps yards in Bedford and the neighboring towns of the Merrimack Valley.
