Can You Plant Trees over a Leach Field?

Leach fields are an essential part of septic systems. They are designed to filter and distribute liquid waste from your home into the ground. Typically, leach fields are covered with grass or other low-growing plants. However, some homeowners may want to plant trees over their leach field for various reasons. In this article, we will explore whether you can plant trees over a leach field and what precautions you should take.

The Risks of Planting Trees over a Leach Field

While it may seem harmless to plant trees over your leach field, there are several risks involved. Trees have deep root systems that can cause damage to your septic system's pipes and tanks. If the roots penetrate the pipes, it can cause blockages and even lead to the failure of the system. Additionally, the roots can draw out moisture from the soil, which can affect the absorption and distribution of liquid waste.

The Types of Trees You Can Plant over a Leach Field

If you decide to plant trees over your leach field, it's important to select the right type of trees. Trees with shallow root systems are the best choice. These include small ornamental trees, fruit trees, and some conifers. However, you still need to take precautions to avoid damaging your septic system. You should always consult with a professional arborist or septic system expert before planting trees over your leach field to ensure that you're making the right choice.

Precautions to Take when Planting Trees over a Leach Field

If you've decided to plant trees over your leach field, here are some precautions you should take:

Consult with a professional arborist or septic system expert to determine the right type of trees for your leach field.

Plant trees at least 50 feet away from your septic system's components to avoid damaging them.

Avoid planting trees with aggressive and invasive root systems.

Consider installing a root barrier around the leach field to prevent the roots from growing into the septic system.

Avoid using fertilizers and chemicals near the leach field as they can damage the system.

Regularly monitor your septic system for signs of damage and maintenance needs.

Conclusion

In summary, while it is possible to plant trees over a leach field, it is not recommended without taking the necessary precautions. Trees with shallow root systems are the best option, but even then, you should consult with a professional to ensure that your septic system is not at risk. By taking the necessary precautions, you can enjoy the beauty of trees without compromising your septic system's function and longevity.
