The Best Companion Plants For Walnut Trees

Walnut trees are a popular choice for home gardens, but they can be challenging to grow. One of the biggest challenges is finding companion plants that will thrive in the walnut tree's shadow and tolerate its toxic juglone secretions.

Juglone is a natural chemical produced by walnut trees that can inhibit the growth of other plants. It is found in the tree's leaves, bark, roots, and nuts. Juglone can kill or stunt the growth of sensitive plants, so it is important to choose companion plants carefully.

There are a number of plants that are tolerant of juglone and can be successfully grown near walnut trees. Some of the best companion plants for walnut trees include:

• Stone fruits: Stone fruits, such as cherries, plums, and peaches, are a good choice for companion plants for walnut trees. They are tolerant of juglone and can provide the walnut tree with shade and support.
• Mulberries: Mulberries are another good choice for companion plants for walnut trees. They are tolerant of juglone and can provide the walnut tree with nitrogen and other nutrients.
