"Planting a tree is an investment in the future, so it is worth your time to select carefully and plant properly. When you visit a nursery, search the web, or peruse a catalog, you will find that nursery stock is available in three forms, depending on how it has been grown or harvested: bare-root, balled and burlapped (B &amp; B), or container-grown."^^<http://www.w3.org/2001/XMLSchema#string>
