Introduction

A septic drain field is a critical component of a septic system, which treats and disposes of wastewater from a residential or commercial property. It consists of a series of pipes or chambers buried underground, through which the wastewater flows and is filtered before it is absorbed by the surrounding soil. The drain field is also an ideal location for planting trees, which can provide shade, reduce erosion, and enhance the aesthetic appeal of the property, among other benefits. However, not all trees are suitable for planting above a septic drain field, as they can cause damage to the pipes and compromise the efficiency of the system. In this article, we will discuss what trees can be safely planted above a septic drain field and why.

Factors to Consider

Before we dive into the types of trees that are suitable for planting above a septic drain field, it's essential to understand the factors that make them compatible with the system. The first and most critical factor is the depth and spread of the tree's roots. Trees with deep, invasive roots can penetrate the pipes and cause blockages, leading to costly repairs and a dysfunctional system. In contrast, trees with shallow roots and a non-aggressive growth habit are less likely to cause damage. The second factor is the water requirements of the tree. Trees that need a lot of water to thrive can disturb the balance of the system by absorbing too much water from the drain field, which can lead to oversaturation and clogging. Finally, the size and weight of the tree should also be considered, as larger trees can exert pressure on the pipes and cause them to crack or collapse.

Types of Trees to Plant

Now that we understand the factors to consider let's look at the types of trees that are safe to plant above a septic drain field. First on the list is ornamental trees, such as dogwood, redbud, and flowering cherry trees. These trees have shallow root systems and typically do not grow more than 25 feet tall, making them ideal for planting above a septic drain field. They also add beauty and color to the landscape, making them a popular choice for many homeowners. Another option is fruit trees, such as apple, peach, and pear trees. These trees also have shallow roots and can produce a bountiful harvest of delicious fruit, making them a practical choice for those who want both beauty and functionality. Finally, evergreen trees, such as arborvitae, spruce, and pine trees, are also suitable for planting above a septic drain field. These trees have a dense, fibrous root system that is less likely to penetrate the pipes and can provide year-round privacy and greenery.

Types of Trees to Avoid

Just as there are trees that are suitable for planting above a septic drain field, there are also trees that should be avoided. These trees have deep, invasive root systems that can damage the pipes and compromise the efficiency of the system. The first on the list is willow trees, which are notorious for their aggressive roots and can cause significant damage to the pipes. Other trees to avoid include oak, ash, and maple trees, which also have deep roots and can quickly spread into the drain field. Additionally, avoid planting large, heavy trees, such as oak and hickory trees, as they can exert too much pressure on the pipes and cause them to crack or collapse.

Conclusion

In conclusion, planting trees above a septic drain field can enhance the beauty and functionality of your property, but it's important to choose the right trees to avoid damage to the system. Always consider the depth and spread of the tree's roots, its water requirements, and its size and weight before planting. Ornamental, fruit, and evergreen trees are all suitable options, while willow, oak, ash, and maple trees should be avoided. By selecting the right trees, you can create a beautiful, sustainable landscape that will provide benefits for years to come.
