Give Metuchen two days of May rain and every lawn on Central Avenue jumps an inch — that is the week a yard either gets ahead or spends all summer chasing. Lucky Landscaping LLC gets ahead of it, mowing on the tight schedule the season demands, edging the walks, trimming the bed borders, putting down seed and fertilizer while the ground is warm and wet enough to use them. Mulch goes in dark, and the cleanups clear out the spring debris and, months later, the autumn drop. What comes of it is the ordinary miracle of a yard that always looks like it was just done. Which, on this route, it usually was.
