West Nyack sits under the long basalt shoulder of the Palisades, and in August the storms come over that ridge fast — green light, twenty minutes of rain, then steam lifting off the grass. J.M. Tree Service & Landscape Corp reads that sky for a living, because mowing is a matter of timing as much as machinery. Cut at the right height at the right hour and a lawn shrugs off the heat instead of scorching under it. The reward comes at the end of the afternoon, when the whole yard reads as one continuous, unbroken green. Lawn care in West Nyack and across Clarkstown.
