Seedlings transplanted to permanent location when 7-8 years old. Trees kept short (2m) and spaced close (2-3m) in commercial plantations for medicinal leaf production; otherwise allowed to grow higher and spaced further for seed production. Slow growing. Leaves harvested in early fall as they begin to turn yellow; dried in sun. Fruits harvested late fall, seeds cleaned and roasted.   Field spacing: 3-5m apart (2-3m within rows for leaf production).   Yield: no data (leaf years 8-50, seed years 20-50).   Pests: few problems   Diseases: tolerates pollution.
