How Far from Leach Field Should You Plant a Tree?

If you have a leach field on your property, planting trees can be a great way to add shade, beauty, and value to your outdoor space. However, planting trees too close to your leach field can also cause serious problems. Trees with deep roots can disrupt the pipes and filtration systems that make up your leach field, leading to costly repairs and even health hazards.

The Risks of Planting Trees Near a Leach Field

Leach fields are made up of a series of pipes and chambers that help to filter and break down wastewater. Trees with deep roots can grow into these pipes and chambers, causing blockages and backups that can lead to serious health hazards. In addition, roots can compromise the integrity of the pipes themselves, leading to leaks and damage that can be difficult and expensive to repair. For these reasons, you should always be careful about where you plant trees in relation to your leach field.

How Far Away Should You Plant Trees?

As a general rule, you should avoid planting trees within 10 to 20 feet of your leach field. This will help to ensure that the roots of the trees do not interfere with the pipes and chambers of your system. In addition, you should also be careful about the types of trees you choose to plant. Trees with shallow, spreading root systems are generally safer than those with deep, invasive roots.

Which Trees Should You Plant Near a Leach Field?

When choosing trees to plant near your leach field, look for species that have shallow, non-invasive roots. Some good options include:

Japanese maple

Crab apple

Redbud

Serviceberry

Dogwood

Lilac

You may also want to consider planting shrubs and low-growing plants near your leach field, as these generally have less of an impact on the pipes and chambers of your system. Good options include lavender, heather, and yarrow.

What if Trees Are Already Planted Near Your Leach Field?

If you already have trees planted near your leach field, it is important to monitor them regularly for signs of problems. Look for signs of root intrusion, such as slowly draining sinks and foul odors in the area. If you notice any of these signs, you may need to have the roots removed or the pipes and chambers repaired or replaced.

By following these guidelines, you can ensure that your leach field remains healthy and functional, while still enjoying the beauty and benefits of trees in your outdoor space.
