What Can I Plant Under a Walnut Tree

Walnut trees are known for their beautiful foliage and delicious nuts. However, they also produce a chemical called juglone that can be toxic to certain plants. So, what can you plant under a walnut tree? Here are some options:

Native plants

One of the best options for planting under a walnut tree is to use native plants. These plants have adapted to the presence of juglone in the soil and are naturally tolerant of it. Some examples of native plants that do well under walnut trees include:

Wild ginger

Virginia bluebells

Columbine

Lupine

Sweet cicely

Goldenrod

Catnip

By using native plants, you can create a beautiful and natural-looking landscape that is less likely to be negatively affected by the presence of juglone.

Vegetables

If you want to plant vegetables under a walnut tree, there are a few options that can tolerate the presence of juglone. These include:

Asparagus

Carrots

Garlic

Beans

Peppers

Radishes

It is important to note that these plants may still be affected by the juglone in the soil, so it is best to plant them away from the trunk of the tree and to monitor their growth closely.

Ground covers

Ground covers are another option for planting under a walnut tree. These plants can help to fill in the space and create a beautiful ground cover that is tolerant of juglone. Some options to consider include:

English ivy

Creeping phlox

Creeping jenny

Periwinkle

Wintergreen

Ground covers can also help to prevent erosion and improve soil quality by adding organic matter to the soil as they grow.

Conclusion

While the presence of juglone in the soil can be challenging, there are still many options for planting under a walnut tree. By using native plants, vegetables tolerant of juglone, and ground covers, you can create a beautiful and diverse landscape that will thrive under the shade and protection of your walnut tree.
