What Can You Plant Under Walnut Trees

Walnut trees are a common sight in many gardens and landscapes. They are not only beautiful but also provide shade and nutritious nuts. However, these trees are notorious for secreting a growth inhibitor known as juglone, which can hinder the growth of many plants. Despite this limitation, there are still a wide variety of plants that can thrive beneath walnut trees. In this article, we will explore some of the best options for planting under walnut trees.

Vegetables

If you want to grow vegetables under walnut trees, you need to choose ones that are tolerant of juglone. These include asparagus, beans, beets, carrots, chard, peas, and peppers. You can also consider planting some shade-loving vegetables like lettuce and spinach, which can benefit from the dappled light that passes through the walnut canopy.

Herbs

Herbs are another option for planting under walnut trees. Some of the herbs that can tolerate juglone include chives, cilantro, dill, oregano, and parsley. You can also try planting some mint, which is not affected by juglone and can help to repel pests like mosquitoes and mice.

Flowers

Many flowers can grow under walnut trees, but you need to choose ones that are both shade-tolerant and juglone-tolerant. Some of the best options include astilbe, lily of the valley, barrenwort, columbine, bleeding heart, and ferns. You can also try planting some shade-loving bulbs like daffodils, hyacinths, and tulips.

Fruits and Berries

If you want to add some fruits and berries to your garden, you can try planting some of the varieties that are resistant to juglone. These include blueberries, currants, elderberries, figs, pawpaws, and persimmons. You can also consider planting some grapes, which are not affected by juglone and can benefit from the shade provided by the walnut canopy.

Conclusion

Although growing plants under walnut trees can be challenging, there are still many options to choose from. By selecting plants that are tolerant of juglone and can thrive in the shade, you can create a beautiful and productive garden that complements your walnut trees. Remember to get your plants tested for tolerance before planting them, and to keep an eye on their growth to ensure they are thriving.
