Can I Plant That? The Do's and Don'ts of Landscaping Over Your Septic Drainfield

Why Landscaping Choices Matter

Did you know that landscaping around your septic system can affect soil compaction, root growth, and water absorption? Heavy features around the drain field can compress the soil and reduce drainage, while other species with aggressive roots can infiltrate pipes or tanks. Additionally, excessive irrigation near this area can oversaturate the soil, obstructing smooth wastewater flow and treatment, which increases the risk of system failure. Before attempting any yard work, consult your local septic company for advice on acceptable plants to mitigate devastating disasters down the line.

Subtle Plants for Landscaping Around Your Septic Unit

The reality is that choosing the right plants to grow around your wastewater treatment system is critical for overall performance and longevity. If you rely on an on-site system, the primary goal of landscaping should be to stabilize the soil without interfering with the different underground components. Here are common plants septic service providers recommend to ensure you make informed decisions.

Shallow-Rooted Plants and Grass

When undertaking a landscaping project, choosing plants with shallow, fibrous roots can make a big impact near your septic unit. Indigenous grasses and ground cover plants are ideal for many residential gardens, as they are adapted to the local conditions and don’t require a lot of water to thrive. Strategically growing these plants around your septic system can help prevent erosion while contributing to air circulation.

Indigenous and Low-Water Plants

When it comes to water-related concerns in your landscape, planting indigenous and low-water plants prevents oversaturation. Whether it is indigenous grasses, perennials, or shrubs, low-water greenery can thrive with minimal irrigation. This unique feature makes these plants suited for the area around your drain field. Additionally, their moderate growth reduces the likelihood of roots reaching tanks and pipes. You don’t have to worry about frequent septic cleaning and repair due to root intrusion.
