West of Kingston the ground begins to climb toward the Back Mountain, and the yards up that grade sit under old trees that keep the grass cool and slow. Foltz Landscaping reads those conditions for what they are — mow a little higher, trim carefully around roots and stone, keep beds and shrub lines drawn where they belong. Landscape maintenance on a slope has its own logic, and following it turns an awkward lot into an easy-looking one. There is genuine pride in a shaded lawn that stays even and green all the way out to the tree line. Work carries from Kingston up the grade into the neighboring boroughs and townships.
