Water: Andean walnut, adapted from mountainous regions, is moderately drought-tolerant. It thrives with a watering schedule of once every 2-3 weeks, benefiting from seasonal rains that provide necessary deep watering rather than frequent light sprinkling, aligning with its growth cycles.

Fertilize: Andean walnut thrives on balanced nutrition with biannual fertilization in spring and late autumn, applying 2-4 ounces per young tree. Nitrogen boosts spring growth, while balance supports fruiting. Prevent root burn by distributing evenly, and water the soil before and after fertilizing for optimal nutrient uptake.

Pruning: Andean walnut features strong foliage and valuable timber. Prune in early spring, focusing on removing dead branches, improving air circulation, and shaping the plant. This practice manages size, stimulates fruit growth, and should be done with clean, sharp tools to promote healing.

Propagation: The hardwood tree andean walnut thrives in well-drained soils and full sunlight. Propagate by sowing seeds directly in fertile soil, ensuring consistent moisture for germination. Protect delicate seedlings from wind and sun, and transplant saplings carefully for successful establishment in permanent locations.
