Valley has planted over 35,000 street trees for the City of New York! We take great pride in planting trees. Every tree gets planted with care. The start to successful tree planting comes from acquiring good nursery stock. We have long lasting relationships with local growers on Long Island. All our trees are planted at proper depth and strategically placed in the planting site. We follow Ansi Z133 (American National Safety Standard for Arboriculture Operations) planting procedures. Valley uses tested topsoil to backfill the holes to ensure maximum growth potential.
