Growing Longleaf Pine Seedlings in Containers
We provide basic guidelines for nursery production of longleaf pine ( Pinus palustris P. Mill. [Pinaceae]) seedlings in containers. The best seedlings are spring sown, grown outdoors in full sun in cavities with a 100-ml (6 in3) volume, 11-cm (4.5 in) depth, and a density around 535 seedlings per m2 (50/ft2). A 1:1 peat moss:vermiculite medium adjusted to pH 4.5 to 5.5 and amended with control-release or soluble fertilizers works well. Planting of container stock generally improves reforestation success because survival is good, the planting season can be extended, and therefore, restoration of the longleaf pine ecosystem is enhanced.
