The Connetquot runs cold and clear the whole year through, indifferent to whether the ground around it is green or frozen — and this work follows the same full calendar. J N Umanzor Landscaping Inc. mows, edges and trims Islip yards through the growing months and clears them at both ends of the year, then turns to plowing driveways, opening walkways and salting once the storms start crossing the island. Snow here tends to arrive wet and heavy, the kind that has to be moved early and moved again. Grass here grows hard from April to October and forgives nothing that gets skipped. Two very different jobs, one steady habit: keep showing up.
