Manalapan Brook wanders through the township without hurrying, and in April the low ground beside it greens up a week ahead of everything else. Grinkevich Lawn & Landscape opens the year right about then — clearing the winter litter, cutting the first wild growth down to something civilized, freshening the mulch so the beds have an edge to them again. From there it settles into the long rhythm of the season: mow, trim, blow off, move on. The good part comes afterward, on the drive past, when a yard looks deliberate instead of accidental. Lawn care in a township that has never entirely stopped being good growing ground.
