The Common in the middle of Rochester turns gold in autumn, and for a few weeks the whole city seems to shed at once. Northeast Landcare LLC handles both ends of that calendar — mowing, trimming, edging and seasonal cleanups while things grow, then plowing, shoveling and salting once the pavement disappears. A cleanup here is a real day's work: leaves off the lawn, out of the beds, gone before the first freeze locks them down. Then the trucks change over and the same addresses get opened up before dawn. Two seasons, the same doorsteps, the same standard.
