Black walnuts are beautiful trees, very
ornamental and a valuable timber tree. They grow very well here in
the Pacific Northwest as well as in other regions of the U.S.
For lumber production, trees should be
planted close together to encourage upright growth and straight trunks.
Plant young trees ten feet apart and thin them twice, to an eventual
spacing of forty feet.
Young trees need to be watered the first
year but once established, grow well without much attention.
Although a bit difficult to extract from their shells, black walnut nuts
are rich and delicious for eating fresh and in baked goods.
