Walnut Tree Companion Plants

If you're looking to grow walnut trees, choosing the right companion plants can be crucial to their success. Walnut trees produce a chemical called juglone, which can inhibit the growth of other plants around them. However, there are certain plants that are resistant to juglone and can thrive in the presence of walnut trees.

In this article, we'll take a look at some of the best companion plants for walnut trees and how you can use them to create a thriving garden.

What is Juglone?

Before we dive into the companion plants, let's take a closer look at juglone. Juglone is a chemical produced by all parts of the walnut tree, including the leaves, bark, and roots. It's toxic to many plants, including tomatoes, peppers, and potatoes, and can cause wilting, yellowing, and eventual death.

The concentration of juglone is highest in the roots of the walnut tree, but it can also be found in the surrounding soil. This means that even after a walnut tree is removed, the soil may still contain juglone for several years.

Companion Plants for Walnut Trees

While many plants are sensitive to juglone, there are some that are resistant to its effects. These plants can be grown as companions to walnut trees, providing a range of benefits including nitrogen fixation, pest control, and soil improvement.

Here are some of the best companion plants for walnut trees:

1. Blackberry

Blackberries are a great companion plant for walnut trees because they're resistant to juglone and can help to suppress weeds. They also attract beneficial insects like pollinators and predatory wasps, which can help to control pests in your garden.

How to Grow Blackberries with Walnut Trees:

Plant blackberries at least 10 feet away from the base of the walnut tree to avoid competition for nutrients. Make sure to keep the area around your blackberry bushes free of weeds to prevent competition for water and nutrients.

2. Garlic

Garlic is another great companion plant for walnut trees because it has natural fungicidal properties that can help to protect your plants from diseases. It's also a natural repellent for many pests, including aphids and spider mites.

How to Grow Garlic with Walnut Trees:

Plant garlic cloves in the fall, before the first frost. Space them about 6 inches apart and bury them about 2 inches deep. Make sure to keep the area around your garlic plants free of weeds to prevent competition for water and nutrients.

Comfrey is a nitrogen-fixing plant that can help to improve the soil around your walnut trees. It's also a great source of nutrients for other plants in your garden.

Other Tips for Companion Planting with Walnut Trees

In addition to choosing the right companion plants, there are a few other things you can do to ensure success when planting near walnut trees:
