The nursery industry has three standard root forms, bareroot (BR), balled and burlapped (B&B), and containerized, each with advantages and disadvantages. This thesis looks to discuss these advantages and disvantages in comparison to a new plant propagation method, Missouri Gravel Bed System (MGBS). Due to the regrowth of the fine roots lost during harvest, BR MBGS trees can be harvested while in full leaf giving the trees the same planting versatility as B&B and containerized trees but at much lighter weight. The larger root mass of the BR MGBS trees may improve survival and establishment and may also have a positive impact in phytoremediation. The pilot experiment, conducted as a part of this thesis, compared growth and success of BR MGBS trees to B&B trees. The results showed that the MGBS can increase root and stem growth over silt loam soil for the phyto species, Populus deltoides x Populus nigra.
