Field production practices: roots Back to root systems
 |
 |
There are many methods of producing trees in field soil. In southeastern US trees are typically planted, irrigated, and root pruned in place without moving trees until digging for sale. In contrast, nurseries in many other parts of the country move trees from one field to another at least once. Soils vary from clays to loams to sands. The following will allow you to learn more about each of these topics.
