Gathering Black Walnuts for starting seedlings

Question

When do you gather the nuts from the tree to start seedlings

Answer 1

You will do this when they drop from the tree in the fall. After planting, they won't germinate till spring. As long as the seed does not feel empty when you remove the husk, it should be viable.
