The Highland streets keep their big old shade trees, and underneath them the grass grows thin and uneven and stubborn — which is exactly where attentive mowing earns its keep. Pimentels Lawn Care takes on those yards: cutting at the height shade wants, trimming around roots, walls and hydrants, edging walks so the sidewalk gets its full width back. Down the hill past the bakeries on Columbia Street the lots are smaller and sunnier and ask for something else entirely. Cleanups come at both ends of the year, when a yard needs resetting rather than maintaining. One city, a hundred different lawns, each of them asking for something slightly different.
