We have a black walnut tree with many large, green, walnuts. Red squireels are busy taking them to their Winter nests, we think. We would like to harvest and plant several of these green walnuts. How would we plant and grow more black walnut trees?

Links to information on gathering the walnuts, steps needed to prepare the walnuts for planting, and planting are below.

This link describes the steps to prepare the seeds for planting:

The link below discusses growing black walnuts, uses of the trees, planting, and general care and maintenance of the trees:

As you may know, since you already have a black walnut tree, there are other plants which may not grow near a black walnut tree due to the toxin, juglone, released by the tree. Below is a list of plants which are resistant to the juglone and those which are affected by the toxin:
