Garden Edging: The Complete Guide to Choosing the Right Edging for Your Landscape

A well-designed garden is often defined by the details.

Plants, lawns, pathways, mulch and decorative stone might be the features that attract attention first, but the way these areas are separated can have a major impact on how neat, practical and finished the overall landscape feels.

That is where garden edging comes in.

Garden edging creates clear boundaries between different areas of your landscape, helping define garden beds, separate lawns from pathways, contain mulch and create cleaner lines throughout the garden.

However, not every edging product works the same way.

From metal and aluminium through to plastic and timber, there are different options available depending on the appearance you want to create, the shape of your garden and how the edging needs to perform.

In this guide, we look at what garden edging is, where it can be used, the different options available and what you should consider when choosing edging for your next landscaping project.

What Is Garden Edging?

Garden edging is a physical border installed between different areas of a landscape.

It can be used between lawn and garden beds, along pathways, around trees, beside paved areas or anywhere you want to create a defined boundary.

While edging can be decorative, its purpose goes well beyond appearance.

A properly planned edge can help contain landscaping materials, maintain the shape of garden beds and make the different areas of a landscape feel more deliberate.

For example, without a defined edge, grass can gradually grow into garden beds while soil, mulch or gravel can move into surrounding areas.

Installing an appropriate edging system creates a clearer separation.

You can explore a range of garden edging options to find a solution suited to your project.

Why Is Garden Edging Important?

It is easy to think of edging as a finishing touch, but it can influence both the appearance and functionality of a landscape.

A garden with clearly defined borders often looks more organised because there is a visual distinction between each area.

Edging can help separate:

• lawns and garden beds
• mulch and turf
• gravel and planted areas
• pathways and surrounding gardens
• paving and soft landscaping
• trees and surrounding lawn
• different levels or sections within a landscape.

This makes edging useful in everything from simple backyard improvements to more detailed landscape designs.

Where Can Garden Edging Be Used?

One of the biggest advantages of garden edging is its versatility.

Different products can be used throughout a landscape depending on the height, strength, flexibility and finish required.

Lawn Edges

Lawn edging creates a defined border between turf and neighbouring areas.

Rather than having lawn gradually spread into a garden bed or pathway, an installed edge establishes a clear boundary.

This can be particularly useful around curved lawns or landscaped areas where maintaining a consistent shape is important.

Garden Beds

Garden beds are one of the most common applications.

Edging helps define the perimeter of the bed and creates separation between plants, soil or mulch and the surrounding lawn or hard landscaping.

It can also become part of the visual design.

A low-profile edge can almost disappear into the landscape, while taller steel edging can create a much more noticeable feature.

Pathways

Edging can be installed alongside garden paths to create cleaner boundaries and help separate pathway materials from nearby garden areas.

The appropriate product will depend on what the pathway is made from and how much support the edge needs to provide.

Around Trees

Circular or curved edging can create a defined area around feature trees.

This can separate the tree from the surrounding lawn and create a dedicated space for mulch or planting.

Prefabricated options such as ShapeScaper rings are another option for creating defined circular features.

Raised Beds and Planters

Some heavier-duty edging systems can be used to create raised garden areas, terracing and planter-style features.

Landscape Supplies Online also offers ShapeScaper boxes and planters for projects where the edging becomes a more prominent part of the landscape design.

What Types of Garden Edging Are Available?

There is no single best edging material for every garden.

The right option depends on the design, budget, installation requirements and expected performance.

Some of the main options include the following.

Metal Garden Edging

Metal garden edging is a popular option when strength, longevity and clean landscape lines are priorities.

Steel edging can create long straight sections as well as curves, making it suitable for contemporary gardens, pathways, lawn borders, raised beds and other landscape features.

Landscape Supplies Online offers ShapeScaper metal edging in multiple finishes, heights and gauges.

Because there are different profiles available, metal edging can be used for much more than a simple lawn border.

It can become part of the structure and appearance of the landscape itself.

Aluminium Garden Edging

Aluminium offers another clean, modern edging solution.

Link Edge aluminium garden edging is designed for applications including lawns, garden beds, paving and landscape features.

One of the attractions of aluminium edging is its flexibility.

It can work particularly well where you want smooth curves and a neat, relatively low-profile boundary.

Different profile heights can also be selected depending on the application.

Plastic Garden Edging

Plastic edging can provide a straightforward solution for many residential garden projects.

It is lightweight, easy to work with and can be bent around different garden shapes.

Landscape Supplies Online's plastic garden edging range includes different heights and lengths, providing options for garden beds and other general landscaping applications.

Plastic can be particularly useful for DIY projects where ease of handling and installation are priorities.

Timber Garden Edging

Timber offers a more natural appearance and can work well in traditional, rustic or heavily planted landscapes.

It can be used to define garden beds, pathways and other landscape areas while complementing natural materials already used throughout the garden.

However, when comparing timber with metal, aluminium or plastic, it is worth considering the conditions where the material will be installed and the level of maintenance you are comfortable with over time.

Choosing Garden Edging for Straight Lines or Curves

The shape of your garden should play an important role in choosing your edging.

For contemporary landscape designs with geometric garden beds, long straight lines can create a sharp architectural appearance.

Curved edges can create a softer, more organic feel.

If your design contains sweeping curves, choose an edging product that can be shaped without creating uneven joins or awkward transitions.

For example, ShapeScaper steel edging is designed to accommodate both straight installations and curves, while Link Edge aluminium is another flexible option for curved landscape designs.

Before ordering, sketch your garden layout and measure the total distance you need to edge.

This gives you a much better idea of both the quantity and type of material required.

Consider How Visible You Want the Edging to Be

Not every garden edge needs to stand out.

In some landscapes, the best result is an edging system that almost disappears once installed.

This places the visual focus on the lawn, plants and other landscaping materials.

In other gardens, the edging itself becomes part of the design.

Weathered steel, for example, can introduce a distinctive natural-looking finish that works particularly well alongside greenery, gravel and other landscape materials.

ShapeScaper REDCOR edging is designed to develop a weathered appearance over time, making it an option where the steel itself contributes to the finished landscape.

Galvanised steel provides a different look.

ShapeScaper galvanised edging begins with a brighter galvanised appearance and gradually develops a more subdued finish.

The right choice ultimately depends on whether you want your edging to blend in or become a visible design feature.

Think About the Height of Your Garden Edging

Height is another important consideration.

A shallow profile may be suitable for defining the edge of turf, while deeper or taller profiles can suit applications such as raised beds, terracing or more substantial landscape separation.

Before choosing a height, consider what the edging needs to achieve.

Ask yourself:

• Is it simply separating two surfaces?
• Does it need to contain soil or mulch?
• Will part of the edging sit above ground?
• Does it need to create a raised garden area?
• Is it being used around a pathway or paving?
• Does the project require additional structural strength?

The answers will help narrow down the most suitable profile.

Consider Strength and Durability

Garden edging lives outdoors and can be exposed to soil, moisture, garden equipment and regular activity.

For that reason, durability should be considered alongside appearance.

If the edge is being installed in a high-use area or is expected to remain part of the landscape for many years, investing in a stronger system may make sense.

Steel products such as ShapeScaper are designed as landscape-grade edging and are available in different gauges depending on the strength required.

For lighter-duty residential applications, aluminium or plastic may provide the functionality you need without requiring a heavier profile.

Rather than automatically choosing the strongest option available, match the material to the demands of the project.

Garden Edging Can Help Create a More Cohesive Landscape

Good landscaping is often about repetition and consistency.

Using the same edging style across multiple areas can help visually connect different parts of the garden.

For example, the same metal edge might run around garden beds, beside a pathway and around a feature tree.

Although each area serves a different purpose, repeating the same material creates continuity.

This is particularly useful when landscaping larger gardens where individual areas can otherwise feel disconnected.

What Colour or Finish Should You Choose?

The finish of your edging can influence the overall character of your landscape.

Black edging can create a clean, understated appearance.

Galvanised steel provides a neutral metallic finish.

Weathered steel introduces warm, earthy tones.

Other finishes can provide a brighter, more architectural look.

There is no universal right answer.

Look at the colours already present in your landscape, including:

• paving
• retaining walls
• fencing
• house exterior
• gravel
• mulch
• outdoor furniture
• planting.

Choosing an edging finish that works with these materials can make the entire garden feel more coordinated.

Is Garden Edging Suitable for DIY Installation?

Many edging products are suitable for DIY landscaping projects.

However, ease of installation depends on the product, soil conditions and complexity of your design.

A simple straight garden bed on relatively level ground may be straightforward.

A large project with tight curves, significant level changes or raised areas will require more planning.

Before installation, make sure you understand what connectors, stakes, pegs or other accessories are required.

For example, ShapeScaper systems use compatible stakes and connectors, while Link Edge has its own connectors, spikes and accessories.

Ordering the complete system from the beginning can make installation significantly smoother.

Common Garden Edging Mistakes to Avoid

Even good-quality edging can produce disappointing results if the project is poorly planned.

One common mistake is choosing the product based purely on appearance.

The edging also needs to be suitable for the application.

Another is failing to measure the area properly. Running short partway through installation can delay the project and potentially create unnecessary joins.

Other mistakes can include:

• choosing an unsuitable height
• not allowing enough material for curves
• using too few stakes or fixings
• creating inconsistent lines
• failing to prepare the installation area
• overlooking the manufacturer's installation recommendations.

Planning the layout before purchasing your materials can prevent many of these issues.

How to Choose the Right Garden Edging

With several options available, the easiest approach is to work backwards from your project.

Start by considering what you need the edging to do.

If you simply need to define a small garden bed, your requirements may be relatively straightforward.

If you are building raised areas, creating large sweeping curves or establishing long-term structural borders, you may want a more substantial metal system.

Next, consider the look.

Do you want the edging hidden or visible?

Modern or natural?

Straight or curved?

Subtle or architectural?

Finally, think about installation and long-term use.

Consider the profile height, material, required accessories and how the edging will interact with the rest of the landscape.

By considering function, appearance and installation together, it becomes much easier to narrow down the right option.

Create Cleaner, More Defined Garden Spaces

The right garden edging can transform the way different areas of your landscape connect.

Whether you want to define lawn edges, contain garden beds, create sweeping curves, build raised landscape features or simply give the garden a more finished appearance, choosing an edging system suited to the project is an important step.
