The December Dip of Loblolly Pine

Several planting date studies with loblolly pine (Pinus taeda) have shown a decline in survival during the month of December. The term “December dip” was coined to describe this phenomenon. The “dip” in survival occurs just before the prime planting season (January and February) and just after the fall planting season (October and November). The exact reason for a decline in survival is unknown but it appears to result from a decline in root growth potential. Some half-sib genotypes of loblolly pine may be more sensitive to the December dip than other genotypes.
