Keene's Main Street runs as wide as a field down to the white steeple on Central Square, and the neighborhoods off it are all deep lots and old shade trees. Kunze Landscape Services works those properties on a weekly rhythm — mowing, trimming, edging the long granite walks, and keeping the beds mulched and tidy under the maples. Shade that heavy makes turf a puzzle, and the pleasure lies in solving it patch by patch until the lawn reads even from the sidewalk. April brings the cleanup that clears winter off the beds; late October brings leaves in waves, and then more waves. Between them is a summer of small, exacting work.
