Spring comes late to this corner of Cumberland County — ice off Pleasant Lake, then mud, then all at once a green so bright it looks brand new. Rocky Roots LLC starts the season right there, raking out the winter's wreckage and getting the first mow down before the grass gets ahead of anybody. The name suits the ground: ledge and glacial stone under a thin skin of soil, and a lawn on top of it that still deserves a straight line. Summer is mowing, trimming and edging on a schedule; autumn is a cleanup once the leaves come down. Otisfield lawns earn their green the hard way, and it shows when someone keeps after them.
