What to Plant Near Walnut Trees

Walnut trees are a beautiful addition to any landscape, but they can be finicky when it comes to what can grow nearby. Due to their tendency to release a chemical called juglone, which can be toxic to other plants, it’s important to carefully consider what you plant near your walnut trees. Here are a few options for plants that are safe to grow alongside walnut trees:

1. Ferns

Ferns are a great choice for planting near walnut trees, as they are not affected by juglone. These leafy plants are low-maintenance and add a lovely touch of greenery to your landscape. Some popular fern varieties to consider include lady ferns, maidenhair ferns, and ostrich ferns.

2. Hostas

Hostas are another option for planting near walnut trees. These shade-loving plants are known for their large, lush leaves and are available in a variety of colors and sizes. They do best in slightly acidic soil, and can thrive even in heavily shaded areas.

3. Hydrangeas

Hydrangeas are a beautiful choice for planting near walnut trees, as they provide a splash of color and can tolerate juglone. These flowers thrive in well-draining soil and do well in partially shaded areas. They come in a variety of colors, including pink, blue, and white, and are known for their large, showy blooms.

4. Japanese Maples

Japanese maples are another option for planting near walnut trees. These trees are known for their striking foliage, which can range from bright red to deep purple. They do well in partial shade and prefer well-draining soil. They are also resistant to juglone, making them a safe choice for planting near walnut trees.

5. Astilbes

Astilbes are a great choice for adding color to your landscape, as they come in a variety of shades, including pink, red, and white. These plants prefer moist, well-drained soil and can thrive in partially shady areas. They are not affected by juglone, making them a safe choice for planting near walnut trees.

Conclusion

When planting near walnut trees, it’s important to choose plants that are tolerant of the chemical juglone that the trees release. Ferns, hostas, hydrangeas, Japanese maples, and astilbes are all great options for adding variety and color to your landscape without risking harm to your plants.
