From the top of Mount Sugarloaf the whole Connecticut valley opens out, farms laid flat and green with the river bending through them. Northeast Tree Care works the yards down inside that view, mowing Deerfield lawns on a steady weekly turn from the first warm stretch onward. Trimming and edging give a property its outline; cleanups in spring and autumn give the year a beginning and an end. There is a particular pleasure in finishing a lawn late in the afternoon, when the ridge throws its shadow east across town. The valley grows things generously, and the work is keeping pace with it.
