Can I Plant Trees Near My Septic Tank?

Many homeowners are unsure whether they should plant trees near their septic tanks. On one hand, trees provide shade, beauty, and help to increase property value. On the other hand, planting trees too close to your septic system can cause serious problems. Below we will discuss the pros and cons of planting trees near septic tanks, and what you can do to safely incorporate trees into your landscaping.

The Risks of Planting Trees Near Your Septic Tank

While a tree's roots may seem small and harmless, they can cause significant damage to septic systems. In search of water and nutrients, tree roots will grow towards your septic tank and often wrap themselves around pipes. This can cause pipes to crack or break, leading to expensive repairs. Additionally, tree roots can clog up your drainage field, leading to back-ups, slow draining, and even septic system failure.

Another risk of planting trees near your septic tank is that they may leach water from the soil. This can cause the soil to dry out and become hard, making it difficult for the septic system to properly absorb effluent. In addition, trees that shed their leaves can cause a build-up of organic material in the drain field, which can also impede proper drainage.

Benefits of Planting Trees Near Your Septic Tank

Despite the risks, there are benefits to planting trees near your septic tank. Trees can help to stabilize the soil, reduce erosion, and provide shade that can help keep your septic tank cooler. Additionally, trees can help to filter pollutants from the air and absorb excess nutrients from your septic system, which can reduce the amount of nitrogen and phosphorus that is released into the environment.

What Types of Trees are Best?

If you are considering planting trees near your septic tank, there are several factors to consider. First, it is important to choose trees that have a shallow root system, so that they will not invade or disrupt your septic system. Some examples of shallow-rooted trees include fruit trees, dogwoods, and red maples. Additionally, you should avoid planting trees that shed a large amount of leaves or woody debris, as this can cause build-up in your drain field.

Tips for Planting Trees Near Your Septic Tank

If you decide to plant trees near your septic tank, there are steps you can take to minimize the risks. First, plant trees at a safe distance from your septic system. As a general rule, trees should be planted at least 50 feet away from your septic tank and drain field, although this distance can vary depending on the size of your septic system and soil conditions.

In addition, be sure to plant trees in soil that is well-draining, and avoid over-watering them. You should also have your septic system inspected and pumped regularly to ensure that it is functioning properly. Regular maintenance can help to prevent root invasion, clogs, and other septic system issues that can be caused by planting trees too close.

The Bottom Line

If you are considering planting trees near your septic tank, it is important to weigh the pros and cons and take steps to mitigate the risks. By choosing shallow-rooted trees, planting at a safe distance, and maintaining your septic system, you can enjoy the benefits of trees without putting your septic system at risk.
