On a clear day the turbines out on the Fenner hills turn slowly above the southern horizon, visible from half the yards in Oneida. Treeland Nursery & Landscaping tends those yards through the growing months — mowing, trimming and edging, mulching beds, and the cleanups that open and close the season. May is the busiest kind of hopeful: everything at once, beds to clear, grass already running ahead of the schedule. The work rewards patience and an eye for line, and the payoff is a property that looks composed rather than merely cut.
