By late September the fields at the eastern edge of Berlin Township carry frost some mornings, and the grass finally slows down enough to be worked with. Tursi's Lawn Care, Inc. treats autumn as the season that decides next spring — mowing, edging, trimming, overseeding thin ground and clearing leaves before they mat down over the crowns. Cool nights over still-warm soil make a narrow window here, and hitting it is the difference between a lawn that limps into April and one that comes up thick. The work looks unglamorous in October and completely obvious in May. That delayed payoff is the part worth taking seriously.
