Fertilizers were applied at different dates during the growing season to orchard ramets of loblolly (Pinus taeda L), slash (Pinus elliottii Engelm. var. elliottii), shortleaf (Pinus echinata Mill.), and Virginia pines (Pinus virginiana Mill.) to determine optimum time to enhance flowering. Depending on species, female flowering was increased by applications in mid- to late summer. Male flowering was increased most by applications in early summer.
