Container longleaf pine (Pinus palustris) seedlings are an alternative to planting bare-root stock, especially when short production times are required, the planting season is extended, or adverse sites are planted. Quality container seedlings are produced under various degrees of environmental control and in several container types. The quality of the planting stock depends on the quality of the seeds sown and proper use and timing of cultural practices. The most critical cultural practices include sowing methods and control of growing medium moisture and seedling nutrition. Seedling root and shoot morphology can be controlled in containers to produce stock of desired characteristics for outplanting under specified conditions. Handling and planting methods used with container longleaf pine will depend on the time of year and physiological condition of the seedlings.
