What Can I Plant on Top of Tree Roots?

Planting on top of tree roots can be a challenge for gardeners, as tree roots can be strong, expansive and invasive. However, with some careful planning and know-how, it is possible to successfully plant on top of tree roots. In this article, we’ll explore some plant options and techniques that can thrive in this type of environment.

Understanding Tree Roots

Before we dive into the plant options, it is important to first understand how tree roots grow and function. Most trees have shallow, spreading roots that grow outward from the trunk, with some roots extending beyond the tree's canopy. These surface roots are responsible for water and nutrient absorption, stability, and can also compete with other plants for resources. Because of their large size and expansive network, they can make it difficult to plant anything near the base of the tree.

Planting Strategies

One of the most effective planting strategies for planting on top of tree roots is to build raised garden beds or planters above ground level. This way, you can create an environment that is separate from the expansive tree roots, giving your plants a better chance of survival. Raised garden beds are made from durable materials and can be filled with high-quality soil that is rich in nutrients. They can also be customized to fit your specific needs and the space available for planting.

In addition to raised garden beds, you can also create a barrier around the tree base using a variety of materials such as plastic sheets, landscaping fabric, or even a layer of bricks or stones. This will help prevent the roots from spreading too close to your plants and will also help to retain moisture in the soil.

Plant Options

When it comes to choosing plants that can thrive on top of tree roots, there are several options to consider. One popular choice is to plant shade-loving groundcovers such as vinca, hostas, or wild ginger. These plants can handle low light conditions and can spread quickly, forming a lush, green ground cover around the base of the tree.

Another option is to plant container gardens with smaller plants that can be moved around and replanted as needed. Container gardens allow you to control the soil and can offer more flexibility in terms of placement and design. You can choose to plant annuals or perennials, depending on your desired level of maintenance and budget.

Finally, you can also consider planting a tree-friendly garden with native plants and shrubs that can thrive in the same environment as the tree's roots. These types of plants are often hardy and can handle the competition for resources with the tree's shallow roots. Some examples of native plants include ferns, columbines, or trilliums.

Conclusion

Planting on top of tree roots is possible with the right techniques and plant choices. Whether you choose to build a raised garden bed, plant in containers, or create a native plant garden, there are many options available to suit your needs and preferences. By taking the time to understand how tree roots grow and function and choosing plants that can thrive in this environment, you can create a beautiful and thriving garden that coexists with the trees in your yard.
