Sunlight
Plant in a location that receives full sun, ideally 6 to 8 hours or more of direct sunlight daily for optimal nut production.
Soil and Fertilizer
Prefers deep, well-draining alluvial soils rich in organic matter. Apply balanced fertilizers supplemented with zinc in early spring.
Pruning
Prune during the dormant winter season to remove dead, diseased, or crossing branches and to shape a strong central leader.

Cultivated varieties are typically propagated by whip, bark, or patch grafting onto established seedling rootstocks in spring.
Seed
Plant stratified nuts directly into the soil in late winter or early spring to grow rootstocks.
