Comprehensive Guide to Planting Over Septic Fields

Introduction

When it comes to maintaining a septic system, most homeowners are primarily concerned with its functionality and longevity. However, the area above your septic field, often referred to as the drain field or leach field, presents a unique opportunity for landscaping. While it’s crucial to be cautious about what you plant in this space, there are plenty of options that can enhance your yard’s aesthetic appeal without compromising the integrity of your septic system.
