Landscaping Your Septic Tank Area: Here's a Guide

A well-maintained garden can enhance the beauty of any property, but when it comes to landscaping around a septic tank and drain field, careful consideration is necessary. Here's a guide to help you choose the right plants for your garden while ensuring the septic system's long-term function.

Vegetable gardens, herb beds, fruit trees, and berry bushes should be located well away from the septic system. This is because frequent maintenance of these gardens could potentially damage the septic system. Instead, opt for plants with shallow, non-invasive root systems that will not damage underground pipes or interfere with the system’s function.

Examples of suitable plants include small trees with shallow roots, such as dogwood trees, Japanese maple, Eastern redbud, and cherry trees. Shrubs like azalea, boxwood, holly, and ornamental cherry are also good choices. Low-maintenance grasses, groundcovers, and wildflowers, such as creeping thyme, ivy, and pachysandra, are also ideal.

These plants are suitable for this purpose because their root systems are shallow and fibrous, reducing the risk of roots growing into and clogging sewer pipes or drain field lines. They require less water or have moderate moisture needs, so their roots are less likely to seek out septic wastewater. Many such plants provide good ground coverage, stabilizing soil and preventing erosion over the drain field without damaging the septic components. Smaller trees with compact root growth offer aesthetic value without threatening the septic system’s integrity. Groundcovers and grasses typically have fibrous roots that help hold soil in place but do not grow deep enough to disrupt septic infrastructure.

On the other hand, large trees or plants with aggressive, deep, or spreading root systems should be avoided near septic systems as they can cause costly damage by infiltrating pipes and drain fields.

When preparing the soil around the septic tank, minimize tilling and cultivation. A thin layer of topsoil is okay, but refrain from adding more than a few inches. Do not lay down any weed barrier fabric, plastic sheeting, gravel, or thick bark mulch, as these can potentially hinder the drainage and functioning of the septic system.

Potted plants, small statues, or lawn ornaments can be used to mark and disguise the access hatch. Raised bed gardens can reduce evaporation, which is important for the septic system to work properly. However, ponds should not be installed near the septic system, as wastewater filtering through a drain field can contain bacteria, residue from household cleaning chemicals, and other harmful substances. These harmful substances can end up in the plants growing on or near the septic system, thus contaminating any fruits, vegetables, or herbs.

By selecting shallow-rooted, drought-tolerant, and noninvasive plants, you can create a safe, attractive landscape around septic tanks and drain fields while protecting the system’s long-term function. Additionally, consider using decorative covers to disguise the access hatch and maintain a well-kept appearance.

1. Vegetables, herbs, fruit trees, and berry bushes should be placed far from the septic system, given their need for frequent maintenance could potentially harm it.
2. In choosing plants, opt for those with shallow, non-invasive root systems like dogwood, Japanese maple, Eastern redbud, cherry trees, azalea, boxwood, holly, ornamental cherry, creeping thyme, ivy, and pachysandra.
3. Avoid large trees or plants with aggressive, deep, or spreading root systems near the septic system as they can cause costly damage by infiltrating pipes and drain fields.
4. When preparing soil around the septic tank, limit tilling and cultivation, and only add a thin layer of topsoil.
5. Potted plants, small statues, or lawn ornaments can help mark and disguise the access hatch, contributing to a well-kept garden lifestyle home-and-garden aesthetic.
6. Raised bed gardens can help reduce evaporation, which is essential for the septic system's proper working, but ponds should not be installed near the septic system as they could contaminate plants with harmful substances.
7. With careful consideration, one can create a safe, attractive landscaping decor around the septic tank and drain field using annuals, perennials, and flowers while protecting the system’s long-term function, catering to pollinators and fostering a healthier lifestyle.
