Water regularly, especially during dry spells, to maintain consistently moist soil. Avoid waterlogged conditions, which can lead to root rot. Deep watering encourages a strong root system. Reduce watering slightly in late summer as the plant matures and prepares for dormancy.

Prune to remove dead, damaged, or crossing branches. Shape the plant for good air circulation and light penetration, which is important for nut development. Early spring, before new growth begins, is the ideal time for major pruning. Light pruning can be done after fruiting.

Propagate by seed, which requires stratification. Sow seeds outdoors in fall or stratify indoors for 3-4 months. Layering and suckers can also be used for propagation. Hardwood cuttings taken in late winter or early spring can also root successfully.

Repot young container-grown plants every 2-3 years to refresh soil and provide more space. Ensure the new pot is only slightly larger than the current one. Repot in early spring before the growing season begins. Mature plants are best left undisturbed in the ground.
