Tree care is an essential aspect of gardening and landscaping, ensuring that trees remain healthy and thrive in their environment. One common issue many homeowners face is dealing with exposed tree roots. These roots can become visible due to various reasons such as soil erosion, tree growth, or human activities like construction. The question of whether you can put dirt on top of exposed tree roots is a complex one, as it involves understanding the tree’s root system, the importance of root health, and the potential consequences of covering these roots. This article aims to provide a detailed exploration of the topic, guiding readers through the process of deciding what to do with exposed tree roots and how to properly care for them.
Understanding Tree Roots
Before diving into the question of covering exposed roots, it’s crucial to understand the role and structure of tree roots. Tree roots are not just anchors that hold the tree in place; they are also responsible for absorbing water and nutrients from the soil. The root system of a tree can be divided into two main parts: the taproot and the fibrous roots. The taproot is the main root that grows straight down into the soil, while the fibrous roots spread out in all directions, forming a network that supports the tree.
The Importance of Root Health
The health of a tree’s roots is directly linked to the overall health and well-being of the tree. Healthy roots are essential for the tree to absorb the necessary nutrients and water, supporting its growth and survival. Exposed roots can be a sign of poor soil conditions, erosion, or human error, and if not addressed, can lead to serious health issues for the tree, including decay, disease, and eventually death. Therefore, it’s vital to approach the situation with care and consider the long-term effects of any action taken on exposed roots.
Why Roots Become Exposed
Roots can become exposed for several reasons, including natural causes like erosion due to heavy rainfall or wind, and human activities such as gardening or construction that alter the soil level around the tree. Sometimes, the roots may naturally grow closer to the surface as the tree ages or if the soil composition changes. Understanding why the roots are exposed can help in determining the best course of action.
The Consequences of Putting Dirt on Exposed Tree Roots
Putting dirt on top of exposed tree roots might seem like an intuitive solution to cover them up and restore the aesthetic appeal of the garden or yard. However, this action can have serious consequences for the tree’s health. Here are some factors to consider:
The primary concern is that adding soil on top of exposed roots can cause them to rot. Roots need oxygen to function properly, and covering them with soil can prevent this oxygen from reaching the roots, leading to decay. Moreover, if the soil added is not of the same quality or composition as the original soil, it can introduce harmful pathogens or alter the soil’s pH, further stressing the tree.
Alternative Solutions
Instead of covering exposed roots with dirt, there are several alternative solutions that can address the issue while preserving the health of the tree.
One approach is to use multipurpose compost or a thin layer of organic mulch around the exposed roots. This not only helps in retaining moisture and regulating soil temperature but also adds nutrients to the soil as it decomposes, promoting a healthy environment for the roots. It’s essential to keep the mulch layer thin (about 2-3 inches) and ensure it does not touch the trunk of the tree to prevent moisture accumulation, which can lead to disease.
Another option is to create a root well or a saucer around the exposed roots. This involves carefully digging a shallow well around the roots and filling it with a mixture of compost and the original soil. The well should be designed in a way that allows for proper drainage to prevent waterlogging, which can be detrimental to the roots.
Professional Advice
Given the potential risks and complexities involved, it’s often advisable to consult with a professional arborist before making any significant changes to the area around exposed tree roots. An arborist can provide a thorough assessment of the tree’s condition, the extent of the root exposure, and recommend the most appropriate course of action. This might include pruning dead or dying roots, treating the area for pests or diseases, or implementing a long-term care plan to ensure the tree’s continued health.

In addition, exposed roots can be a tripping hazard and can cause damage to lawns, sidewalks, and other surrounding features.
To mitigate these risks, it is essential to take steps to protect the exposed roots. This can include mulching around the base of the tree to retain moisture and regulate soil temperature, as well as installing a root barrier to prevent further root growth and exposure. It is also crucial to avoid compacting the soil around the exposed roots, as this can cause further damage and stress to the tree. By taking these precautions, homeowners can help to minimize the risks associated with exposed tree roots and promote the overall health and well-being of their trees.
Can you put dirt on top of exposed tree roots?
While it may seem like a simple solution to cover exposed tree roots with dirt, this approach can actually do more harm than good. Adding dirt on top of exposed roots can cause the roots to become suffocated, as the soil can prevent them from receiving the oxygen they need to function properly. This can lead to root rot and other health problems, which can ultimately cause the tree to decline or even die. Furthermore, adding dirt can also alter the soil grade around the tree, which can affect the tree’s ability to absorb water and nutrients.
Instead of adding dirt, it is recommended to mulch around the base of the tree to a depth of 2-3 inches. This can help to retain moisture, regulate soil temperature, and suppress weeds that may compete with the tree for water and nutrients. It is also essential to ensure that the mulch is kept a few inches away from the tree trunk to prevent moisture from accumulating and causing rot. By taking a thoughtful and informed approach to managing exposed tree roots, homeowners can help to promote the health and well-being of their trees, while also maintaining a safe and attractive landscape.
