The sycamores along the Raritan hold their leaves late, then let go all at once in an October wind. Blackwood tree services spends that stretch on leaf cleanup across Bound Brook — raking out fence lines and foundation beds, blowing the lawn clean, taking the load away instead of leaving it piled at the curb. Before that comes the long mowing season, cuts kept even and edges kept sharp from the first warm weeks onward. After the last cut, the lawn goes into the cold short, clear and ready. There is a plain satisfaction in a yard that looks finished in November.
