The first mow of the year in Woodbury Heights usually lands in April, when the ground down toward the creek has finally given up its winter water and the grass comes on all at once. Casablanca Landscaping LLC starts there — a clearing first, the winter's litter and leaf pulled out of the beds, then the season's opening cut set high and even. From then on it is a steady turn: mowing, trimming around posts and hydrants and the corners a mower cannot reach, edging that gives every walk a crisp dark border. The borough's blocks are short and the lawns face each other, so the work is on display all summer long. It ends in November the way it began, with a full clearing and a yard that looks settled for the cold.
