Homeowner Growing and Maintenance Tips:
Prefers moist, organically rich, well-drained soil and full sun. Avoid planting in shade. Plants are difficult to transplant due to their deep taproot. Young trees may produce nuts at 4-6 years old but often it takes up to 20 years for a large crop of nuts. Plants benefit from fertilization but do your research as to the correct age of the tree and how often it is best to fertilize.
