Safe Shrubs for Septic System Landscaping
Planning to beautify the outdoor space near a septic system? Choosing the right plants is crucial to preserving the system's function while enhancing your landscape.
Why Planting Near Septic Systems Requires Care
A septic system operates underground, and planting deeply rooted or water-loving plants nearby can lead to costly problems. Roots may infiltrate and damage pipes, while heavy watering can compact soil or flood the system. Yet, a thoughtful choice of landscaping can stabilize the ground, absorb excess water, and prevent erosion.
What Makes a Shrub Safe for Septic Areas?
The key to finding leach-field-friendly shrubs is to look for shallow root systems and drought-tolerant traits. Shallow-rooted shrubs are less likely to interfere with the septic lines, and plants requiring minimal water reduce the risk of soil shifting around the tank.
Recommended Shrubs for Septic Systems
Below are some safe shrub options you can consider planting—at least 10–20 feet away from the septic system to minimize any risk.
| Shrub | Root Behavior | Planting Distance |
|---|---|---|
| Boxwood | Non-aggressive | 10–15 feet |
| Holly | Moderate roots | 15–20 feet |
| Arborvitae | Controlled with proper spacing | 20+ feet |
Shrubs and Trees to Avoid
Certain species pose a high risk due to invasively seeking moisture. Avoid planting the following trees and shrubs near your septic area:
- Willows, poplars, and maples (except Japanese maple) due to their aggressive root systems.
- Birch, elm, and other water-seeking species that can invade septic pipes.
Landscaping Tips for Healthy Septic Systems
Here are some best practices to harmonize landscaping with your septic system’s needs:
- Use root barriers if you’re planting moderately-rooted shrubs.
- Avoid heavy foot or equipment traffic above the drain field to prevent soil compaction.
- Monitor for any signs of system trouble, like water pooling, which may indicate the need for professional help.
Plants That Pair Well with Shrubs
Consider pairing septic-safe shrubs with native grasses or flowering perennials like bee balm or iris for a vibrant landscape. These plants have shallow roots and add visual interest without compromising the septic system's function.
