Can You Plant Fruit Trees Near Walnut Trees?

Walnut trees are a great addition to any garden or orchard. Not only do they provide delicious nuts, but they also offer shade and shelter for other plants and wildlife. However, one question that often arises for those who are looking to plant fruit trees is whether or not they can be planted near walnut trees.

Black Walnut Trees Release a Chemical That Inhibits Growth

It is important to understand that black walnut trees release a chemical called juglone. Juglone is a natural toxin that is released through the roots, nut husks, and leaves of the tree. This chemical can have a negative impact on the growth of nearby plants, especially fruit trees. Juglone can stop the growth of fruit tree roots, and cause leaf yellowing and leaf drop.

Some Fruit Trees are More Resistant to Juglone than Others

Despite the potency of juglone, there are fruit trees that can tolerate being planted near black walnut trees. Some of the most resistant fruit trees include apple, cherry, pear, peach, plum, and apricot trees. These trees produce relatively shallow roots and are less affected by juglone.

Consider the Distance Between Trees When Planting

If you are looking to plant fruit trees near the black walnut trees, it is advisable to plant them at a safe distance. The further the fruit trees are from the black walnut tree, the less likely they are to be affected by juglone. Experts recommend planting fruit trees at least 50 feet away from black walnut trees.

Using Raised Beds Can Help

Another way to ensure that your fruit trees are not affected by juglone is by planting them in raised beds. This method will keep the fruit tree roots from coming into direct contact with the soil that has been impacted by juglone. As a result, the fruit trees can grow without being stunted by juglone.

Final Thoughts

Overall, planting fruit trees near walnut trees is possible, but it requires careful planning and consideration. If you choose to do so, make sure to research the specific fruit tree you would like to plant and its sensitivity to juglone. Additionally, it is important to consider the distance between the walnut tree and the fruit tree, and to take precautions such as using raised beds. By following these guidelines, you can enjoy a bountiful garden or orchard of both walnuts and fruit for years to come.
