10 Worst Trees for Septic Systems

Trees add beauty, shade and value to your Tacoma, WA, property. However, their roots often cause problems for a home’s plumbing system. If you’re thinking about planting a new tree on your property, these are the 10 worst ones for your home’s septic system.

1. Willows

Willow trees are tall and wide. As such, they need a large root system. Their roots are known to spread far and wide in search of moisture.

2. Beech

Beeches are known for their longevity and height. They’re also known for shallow roots that grow vigorously. If you cut down a beech, its roots will send up shoots that form new trees.

3. Eucalyptus

The eucalyptus tree’s roots can spread up to 100 feet away from the tree’s trunk. New trees will regrow from roots after the main tree is cut.

4. Honey Locust

Honey locust trees also form extensive root systems. Those root systems send up suckers that create new trees and more roots.

5. Mulberry

To make berries, mulberry trees grow extensive root systems. Those roots grow quickly toward the moisture in old pipes.

6. Aspen

Aspen tree roots spread up to 100 yards in all directions. Those roots send up new trees, forming thickets. These root systems damage old pipes.

7. Empress

Empress trees grow up to five feet taller each year. In order to do that, they also grow a huge root system to collect moisture from the soil.

8. Elm

Elm trees are adaptable to drought conditions. However, they’ll quickly grow more roots in the direction of leaky old pipes.

9. Poplar

Poplar trees have a short lifespan and invasive root systems. Their roots are tough and push apart pipe offsets.

10. Silver Maple

These maples grow woody root systems near the soil surface. Those roots push up sidewalks, driveways and septic plumbing.
