Limited availability from commercial vendors.
Seed must be stored moist for a short time only. Seed germination is
improved by stratification. Seeds germinate readily at most temperatures if
protected from grubs and other depredation. Seeds may die if moisture falls
below 20 - 22%.
Seedlings develop a deep tap root and extensive lateral roots, making the
species difficult to transplant, though bag or pot-grown trees can readily be
Best success has been observed with small bare root seedlings which
require watering to reduce transplant shock.
