The nut

Apart from money, the Black Walnut also bears delicious walnuts. The perfumed smooth and round nut shell is highly aromatic. The true nut is sweet and spicy, many will tell you that they make the best pies. As the shell is very hard, you will need a more solid tool than the common nut cracker to get the nut out of the shell!

Cultivation

This nut tree needs a sunny spot and well drained, rich soil. Well drained clay is its favourite place to be. The tree will survive being drowned in water for two weeks in spring, but no more than that. The Black Walnut will grow in temperatures as low as those experienced in zone 3, but needs to be in  zone 4 or warmer to produce nuts. Many Black Walnut are not hardy to zone 3. The seedlings we grow here are born from parents with a winterproof genetic that can withstand -47 degrees Celsius. The Black Walnut is a fast-growing tree that can reach 30 metres high and a 10-metre branch spread. It is also used as a medicinal plant as it has antifungal properties.

Juglone toxicity

The Black Walnut is a member of the Juglans family. Its roots produce a substance named juglone that is toxic to various plants, inclusive of apple trees, tomato, potato, cabbage, eggplant, blueberry, azalea, rhododendron, lilac, red pine and the like.

Financial Investment

The Black Walnut (Juglans nigra) wood is very rare and therefore very expensive. It is a long-term investment as a 25 year old tree can have a value up to $15,000. Your initial outlay will be $20. What bank can offer you even $100 after 25 years?
