Immediate release needed for maximum growth of seeded loblolly pine
Seeded lob lolly pine should be released from overtopping hardwoods early in the first growing season. Delaying release for 1 or 2 years substantially reduces height growth regardless of site or cover conditions, and it may result in seriously depleted stocking. On average or better sites, seeding failures rarely occur when hardwoods are deadened promptly. However, on severe sites, even when seedlings are released, first-year mortality can be high in a dry year. But it is on these sites that early release. is most valuable, because pines can survive harsh conditions better when freed promptly from overstory hardwoods. These are the conclusions from studies made during 3 consecutive years near Alexandria, La.
