White pines stand tall around Walden and drop needles on half the lawns in Concord, which is its own kind of seasonal chore. Manero Brothers Landscaping llc handles it along with everything else — mowing on rotation, trimming around trunks and posts, edging walkways, and laying mulch that gives the beds their shape back. The spring round opens a yard up after the thaw; the fall round runs right through the heavy leaf drop out by the orchards and along the road. A Concord lawn wants to be cut at the right height and cut often, and that steadiness shows by midsummer. It is straightforward work, and the result speaks plainly from the street.
