Sunderland sits on some of the darkest, flattest dirt in Massachusetts, and the old tobacco barns still stand out in the fields with their sides propped open to the wind. Halcyon Homesteads Garden Services works the home ground beside all that farmland: mowing, trimming, edging, mulching beds, seeding bare patches and clearing the yard in spring and fall. Bottomland lawns grow fast in June and want a steady hand more than a heavy one. Standing at the end of a mown yard with the barn rows running off toward the far tree line is a fine way to finish a Tuesday. Lawn and garden care in Sunderland, Deerfield, Whately and Montague.
