Can I grow Trees from the fruit that our Black Walnut trees drop?

"We recently moved to Indiana two years ago and I live in zone 5 and need some information on Black Walnut Trees we have several of them in our yard and they drop walnuts every year. I would like to know if I can plant the walnuts that drop from the trees? I have heard that you should not plant a vegetable garden or flowers near the black walnut trees. Is this true and why? Thank you for you time. Jacqueline"

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."
