Goals l.jpg


  • Long-term goal—maximize economic returns over the life of the orchard.

  • Short-term goal—reach economic production in the shortest time possible.

    • The kids gotta eat and bank’s gotta get paid!

Important things I’m not going to dwell on today

  • Site selection

  • Pre-planting soil modifications

  • Nursery tree size

  • Potted vs. bareroot

  • Pre-plant tree care

  • Irrigation & nutrition

Genetics cultivar precocity l.jpg

Genetics: Cultivar Precocity

  • Precocity is the relative amount of time it takes for a tree to come into production.

  • Highly precocious cultivars have a tendency to over-bear once they are mature

    • alternate bearing

    • poor nut quality

‘Bradley’ (‘Ideal’)









‘Cape Fear’

Genetics rootstock vigor l.jpg

Genetics: Rootstock Vigor

  • Generally, high vigor and precocity are considered linked in pecan.

  • High vigor:

    • Cross-pollinated nuts

    • Complete dichogamy

    • Southern parentage

Planting density l.jpg

Planting Density

  • Initially, yield should be proportional to tree planting density.

Training l.jpg


  • Two truths:

    • Training young pecan trees is essential to growing a tree that is workable through the life of the orchard.

    • Pruning young pecan trees delays cropping.

Prune young pecan trees, but remove as little wood as possible!

Remove basal primary buds on central leader during dormant pruning.

At Planting

Year 2

Use a combination of winter and early-summer pruning to minimize the amount of wood cut.
