<p>A process for growing nursery stock (e.g. trees, shrubs, etc.) involving the specific improvement of confining root propagation to a nonwoven porous polypropylene fabric bag (12) such that growth through the bag (12) is severely constricted at the fabric (16), producing a girdling effect (22) and root branching (24) within the bag. Such a process leads to a tightly packed, highly root branched soil ball even in loose sandy loam that is easily removed from the field, readily transported and effective in re-establishing the tree (10) upon transplanting even during the hot summer months. </p> |
