Landscape edging is one of the most overlooked yet impactful elements in outdoor design, providing a clear visual boundary while helping landscapes function better over time.
Whether separating lawn from planting beds, defining walkways, or controlling mulch and gravel, the right edging material improves both aesthetics and maintenance.
For homeowners, landscape edging offers a way to keep yards tidy and intentional. For landscape designers, it becomes a detailing tool that reinforces geometry, hierarchy, and material transitions.
Understanding what edging is in landscaping, and how to install edging properly, helps ensure long-term performance and visual clarity.
How to Install Landscape Edging
Installing landscape edging correctly is just as important as choosing the right material. While installation methods vary by edging type, the core principles remain the same across residential landscapes. Understanding these fundamentals helps ensure clean lines, long-term durability, and minimal maintenance issues over time.
Planning the Edge Layout
Successful edging begins with clearly defining where one surface transitions to another. Straight runs emphasize structure and formality, while gentle curves feel more organic and relaxed. Poorly planned layouts are difficult to correct once edging is installed.
Preparing the Ground
Most edging materials require some degree of excavation or grading to sit properly at grade. A consistent trench depth helps edging remain level and prevents sections from rising or sinking over time. This step is especially critical in freeze-thaw climates.
Setting the Edging at the Correct Height
Edging should typically sit slightly below or flush with the surrounding grade to remain visually discreet. When edging is installed too high, it becomes a tripping hazard and visually distracting, but designers specify this as a look to appear like a planter. Subtlety is often what makes edging feel professional.
Securing and Supporting the Material
Depending on the material, edging may be staked, pinned, mortared, or supported by compacted soil. Proper anchoring prevents movement caused by soil expansion, foot traffic, or maintenance equipment. Longevity depends more on this step than the material itself.
Finishing and Backfilling
Backfilling soil, gravel, or mulch tightly against the edging locks it in place and reinforces the edge visually. Clean finishing lines are what separate amateur installations from professional-grade landscapes.
Plastic Landscape Edging
Plastic landscape edging is defined by its flexibility, light weight, and accessibility, making it a common choice in residential landscapes.
Typically manufactured from recycled plastics, it is designed to bend easily and accommodate curved planting beds without specialized tools. Its low-profile design allows it to remain mostly hidden once installed, helping maintain visual separation without drawing attention to the edge itself.
Plastic edging is highly dependent on proper staking and soil compaction to perform adequately over time. While not ideal for permanent or design-forward projects, it remains a practical solution for budget-conscious installations.
Plastic Edging at a Glance
Types of Plastic Landscape Edging
- Flexible polyethylene edging – Most common; easily shaped for curves
- Rigid plastic edging – Slightly more structured but less adaptable
Durability: Low to moderate
Cost: Low
Appearance: Minimal, often concealed
Best for: Informal gardens, DIY projects
Limitations: Can shift, warp, or surface over time
Considerations: Plastic edging prioritizes ease and affordability over longevity.
Metal Landscape Edging
Metal landscape edging is valued for its structural integrity, precision, and refined visual character.
Unlike flexible materials, metal creates crisp, deliberate lines that reinforce geometry and spatial organization in the landscape. It resists warping, shifting, and degradation far better than plastic or wood, making it a long-term solution for both residential and professional projects.
Metal edging also excels at grade separation, allowing designers to control soil, mulch, and gravel with minimal visual intrusion. Because of its durability and clean detailing, metal landscape edging is often considered the benchmark for modern and architecturally driven landscapes.

Concrete Landscape Edging
Concrete landscape edging provides permanence, weight, and structural stability unmatched by lighter materials. It forms a strong physical boundary that resists soil movement, foot traffic, and environmental wear.
Concrete edging is often used where durability and long-term performance are critical, particularly near hardscapes or high-use areas. Its neutral appearance allows it to blend into both modern and traditional designs depending on finish and detailing. Because it is difficult to modify once installed, concrete edging is best suited for well-planned, permanent landscapes.
