Pecan Orchard Establishment

Making Your Orchard Yield Nuts (and $) as Soon as Possible

Richard Heerema

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 l.jpg

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

Very Precocious


‘Bradley’ (‘Ideal’)









‘Cape Fear’







  • ‘Apache’

  • ‘Caddo’

  • ‘Choctaw’

  • ‘Desirable’

  • ‘Kanza’

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!

Training15 l.jpg


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.
