  2. Keys 1. Well-prepared, competition-free sites 2. Healthy, top-quality seedlings Bareroot or Container? Storage Length 3. Meticulous care and careful planting Proper Handling Planting Depth Plant Early 4. Proper post-planting care

  3. “There is a strong, direct, and positive correlation between percent survival and initiation of height growth with intensity of site preparation” (NCFS Forestry Note No. 61, “Establishment and Growth of Longleaf Pine on Droughty Sites in North Carolina, May 1988”

  4. Importance of Site Preparation “Longleaf . . . will grow best in the complete absence of all competition, . . . ” (“Silvics of North America”, Vol. 1, USDA, Forest Service, Ag. Handbook 654) “. . . it is imperative that adequate site prep be completed prior to tree planting . . .” (Don H. “Zippo” Robbins, 1996 memo to Technical Development Unit)

  5. Keys 1. Well-prepared, competition-free sites 2. Healthy, top-quality seedlings Bareroot or Container? Storage Length 3.Meticulous care and careful planting Proper Handling Planting Depth Plant Early 4. Proper post-planting care

  6. Top QualityBareroot Longleaf Seedlings • Fibrous root system with RCD > .4 inch • Tap root > 6 inches • 5 or more first order lateral roots • Moist roots • Healthy foliage

  7. Top Quality Containerized Longleaf • Needle length must be at least 4” long • Plugs must be at least 5.5 cu.in. in volume and at least 4.5” deep (4.75”) • Root collar diameter < .20” • Cull “floppies”

  8. Container or Bareroot • 1995 Region-wide survey

  9. Bareroot vs Container • Texas study 1994, loamy sand, cutover • Container LL- 93% • Bareroot LL- 12%

  10. Bareroot or Container? • Success with either if proper care and planting techniques are applied. • Machine planted bareroot better survival than hand planted bareroot

  11. Sonderegger Pines

  12. Sonderegger “Guidelines” • Stem Elongation <1 1/2 inches • difficult to recognize and have LL characteristics • Count as cull on Quality Tree planting Inspections, but if tract scores 75-85% due to sonderegger cull - OK to Cost Share • < 75% ARF OK required

  13. Storage issues • Bareroot - Length of storage critical! • Keep to a minimum • No more than 10 days • Container - Storage not as critical • Keep to a minimum • 2 weeks • Seedlings must be acclimated to colder weather (hardened-off)

  14. Effects of RCD and Storage on Bareroot Longleaf Survival Adapted from a study by White

  15. Study results ………..

  16. Keys 1. Well-prepared, competition-free sites 2. Healthy, top-quality seedlings Bareroot or Container? Storage Length 3. Meticulous care and careful planting Proper Handling Planting Depth Plant Early 4. Proper post-planting care

  17. Planting Depth • Do not cover terminal bud • Bareroot with bud at ground level • Container - keep bud above ground, anticipate washing or erosion, error shallow rather than deep

  18. SHALLOW 1 1/2” DEEP 1”

  27. Planting Methods • Hand Planting • Handle the seedlings carefully, protect them from the sun and wind. 2 minutes of root exposure in severe condition can kill trees.

  29. Early Planting

  32. Florida pusley

  33. Texas panicum

  34. Morning glory & Sicklepod

  35. Ag Fields Problems • Erratic survival for site treated with Oust or Velpar • High pH > 6.5 increases the activity of OUST - Limit to 1 oz. per broadcast acre • Soil OM at < 2% increases VELPAR activity- limit to 21 oz. per broadcast acre & OUSTAR to10 oz. (equal to 22oz of VELPAR and 1.5 oz. of OUST) • Do a SOIL TEST!!!
