There is one week in May when Ridgeway smells like nothing on earth but cut grass, and that week gives the whole year its shape. Lawn King of White Plains is out in it — mowing on a rhythm, walking the edges back to a straight line, trimming the fence posts and the mailbox where a machine can't sit level. Through summer the routine holds: feed the turf, keep the height right through the heat, refresh the mulch so the green above it stays sharp. Fall means leaves gone before they mat down; April means the cleanup that gives everything a running start. A lawn kept on schedule asks for very little, and it shows every bit of what it is given.
