Can I grow Trees from the fruit that our Black Walnut trees drop?
Yes, you can start new walnuts from the nuts your trees drop. Simply collect them in the fall and bury them under a couple of inches of soil and/or mulch. The nuts need to experience a winter outside to germinate. The roots of walnut trees give off a substance called juglone that inhibits the growth of other plants and is toxic to some species such as tomatoes. It's a natural way the trees fight off competitors. That's why growing veggies and certain other plants is very hard to do and not recommended."
