Planted Pines Grow Better Than Seeded Pines On Hardwood-Dominated Site
Planted loblolly and slash pines grew faster than seeded pines on an upland site in Louisianna that was dominated by low-quality hardwoods before the seedlings were released. For both species, the height difference at age 9 years was equivalent to about 1 year's growth. Ever since direct seeding became operational, landowners have debated how the growth rates of planted and seeded stands compare. When loblolly and slash pines are established on grassy sites that have had no mechanical preparation, planted trees excel in early years. But for direct seeding, preparation by furrowing or disking is recommended as standard practice, and seeded trees on prepared sites grow as fast as 1-0 seedlings planted in a grass rough 2,3.
