Field performance of container-grown pine (Pinus sp.) seedlings is affected by the type of container, the degree of site preparation prior to outplanting, and the quality of the site. Growing fewer container seedlings per unit area usually produces larger, better quality stock that performs well in the field. The ability of the root systems of container seedlings to become quickly established is particularly important on droughty or stressed planting sites. Need for extensive site preparation is important for longleaf pine (P. palustrus Mill.) establishment, this species clearly is extremely sensitive to competition, especially on adverse sites.
