Now is the time for harvesting and processing black walnut (Juglans nigra of the Juglandaceae family). The green hull will go into organic cold pressed olive for a therapeutic anti-fungal oil-come-salve and the musky-flavored nut meat will go into our mouths. Prized for its wood in furniture-making, this large, native Eastern North American tree can be found growing in USDA zones 4-9. Now is the time for gathering these fallen fruits.
