Growth Stages

1

Establishment

2-3 years

Young tree develops root system and branch framework; vigorous upright growth

Water deeply and regularly; stake if needed; avoid heavy pruning; apply zinc fertilizer; protect from sunscald with tree wrap

2

Pre-bearing

2-3 years

Tree grows taller and fuller; lateral branches develop secondary growth; canopy becomes more dense

Continue zinc supplementation; prune to develop strong central leader and scaffold branches; maintain consistent moisture; remove dead/diseased wood

3

Early Bearing

2-3 years

First flowers appear in catkins; light to moderate nut production begins; tree reaches 20-30 feet

Ensure cross-pollination with compatible male flowering tree nearby; monitor for nutrient deficiencies; thin excessive fruit clusters if needed; maintain irrigation

4

Full Production

15-25+ years

Heavy flowering and nut set; mature tree reaches full canopy; produces 40-100+ pounds of nuts annually

Fertilize with balanced NPK plus zinc; thin if nut clusters are excessive; maintain consistent irrigation during kernel fill; prune only to remove dead wood or shape

5

Harvest & Post-Harvest

August-November

Nuts mature in husks; hulls split and darken; nuts fall to ground in late summer/early fall

Collect fallen nuts regularly; hull and dry properly to prevent mold; store in cool, dry conditions; monitor for pest/disease issues during dormancy

Common Pests

  • Pheromone traps; kaolin clay sprays; dormant oil in late winter; remove infested nuts; insecticides if necessary

  • Remove and destroy fallen nuts promptly; spinosad sprays during emergence; maintain sanitation; overhead irrigation to disturb pupae

  • Remove desiccated fruit; mating disruption pheromones; clean up shell fragments; dormant oil application

  • Overhead watering; sulfur sprays; horticultural oils; predatory mites; avoid over-nitrogen fertilization

  • Strong water spray; insecticidal soap; neem oil; encourage natural predators; parasitic wasps

Harvest Tips

Harvest in late August through October when husks split and nuts fall naturally. Use a mechanical shaker for commercial operations or collect fallen nuts from the ground. Nuts should be hulled within 2-3 days of harvest; hull with a mechanical huller or concrete surface. Dry nuts to 5-7% moisture content in warm, well-ventilated conditions before storage. Store in cool, dry location at 32-50°F with low humidity for long-term keeping.

Fun Facts

  • 🌱 English Walnut Tulare was specifically bred at UC Davis for California's Central Valley climate and is one of the leading commercial cultivars in the United States.
  • 🌱 Walnut trees are famous for producing juglone, a naturally occurring plant chemical in roots, leaves, and stems that inhibits growth of many nearby plants—this is why companion planting near walnuts requires careful plant selection.
  • 🌱 A mature English Walnut Tulare can live for 100+ years and continue producing high-quality nuts well into old age, making it a valuable multi-generational investment.
