Identifying Trees and Plants with Large Roots Near Your Home and Their Impact on Septic Systems
Certain species of trees and plants are notorious for their aggressive root systems, which can cause significant damage to septic systems. While almost all trees pose a risk, some are more problematic than others. Understanding which types of trees and plants to avoid or control is crucial for maintaining your septic system's health and function.
Damaging Trees
When it comes to trees with large and invasive root systems, several types stand out as particularly destructive culprits.
Willow
Willow (Sals spp.) Willows are infamous for their powerful roots, which seek out moisture and can infiltrate septic systems with alarming speed. Due to their extensive root system, willows can easily bypass sandy or gravel surfaces that act as a natural barrier, making them highly prone to damaging septic systems.
Maple
Many species of maple, such as red maples and silver maples, have extensive root systems. These roots can grow towards and invade septic lines, creating blockages and damage over time. The aggressive growth of maple roots can pose a serious threat to the proper functioning of your septic system.
Oak
Quercus spp. (Oak Trees) Oak trees have large and deep roots that can potentially damage pipes and the surrounding soil. Their roots can grow aggressively, extending far from the trunk, and can pierce through septic lines or disrupt the integrity of the system in various ways.
Poplar
Populus spp. (Poplar Trees) Poplars are known for their fast growth and aggressive root systems. These roots can extend far from the trunk, making them a considerable threat to septic systems. Their rapid expansion can cause numerous issues, including pipeline damage and blockages in nearby areas.
Birch
Betula spp. (Birch Trees) Birch trees also have invasive roots that can disrupt septic systems. Their root systems can grow rapidly and spread widely, making Birch an undesirable choice for landscaping near septic tanks.
Harmful Plants
Plants can also pose a threat to septic systems, although typically not as severe as trees. However, certain aggressive plants can interfere with the system if planted too close.
Bamboo
Bambusoideae (Bamboo) Bamboo is a fast-spreading plant with extensive root systems. If left unchecked, bamboo's roots can damage septic components, including drain fields and pipes. Additionally, its rapid growth can quickly overwhelm the space near septic systems.
Vines
Hanging Vines (e.g., English Ivy, Wisteria) Certain climbing vines can wrap around and penetrate septic systems, often causing blockages and disruptions. While not as destructive as some trees, these vines need to be managed carefully to avoid potential damage.
Perennial Grasses
Fescue, Bermuda Grass (Grasses) Some aggressive grasses can interfere with your septic system if planted too close. While not usually as problematic as trees, these grasses can still cause issues if they grow into septic components or if their roots become entangled with drainage lines.
Recommendations
To minimize the risk of root damage to your septic system, it's important to follow these recommendations:
Distance
It is generally advised to plant trees and large shrubs at least 10-15 feet away from septic systems. This distance helps to reduce the likelihood of root infiltration into the septic components.
Root Barriers
Installing root barriers can prevent roots from reaching the septic system. Root barriers are physical barriers that are installed around the septic components, effectively blocking the roots' growth.
Regular Maintenance
Regular inspections and maintenance of your septic system can help catch any issues before they become major problems. This includes checking for signs of root intrusion and addressing any blockages or damages promptly.
If you are considering landscaping near a septic system, it is wise to choose species with less aggressive root systems to avoid potential damage. By following these guidelines, you can better protect your septic system and ensure its long-term functionality.
