Mastering the Art of Metal Edging: A Guide for Landscape Perfection

Metal edging is a sleek, durable solution to give your landscaping projects a professionally finished look. Not only does it offer an aesthetic edge to garden beds and pathways, but it also serves as a practical barrier against grass and weeds, ensuring that your design remains intact. Choosing the best metal edging for landscaping can mean the difference between a good garden and a great one.

Let’s dive into the process of installing this game-changer in your garden.

Why Choose Metal?

Landscaping is not just about choosing the right plants and arranging them aesthetically; it’s also about the finer details like edging. Edging plays a crucial role in defining the boundaries of your garden beds, pathways, and other landscaping features. While various materials can be used for edging, metal consistently stands out as a top choice for several compelling reasons.

AluminumLightweight, yet highly durable.
IronProvides unmatched strength.

One of the primary reasons to opt for metal edging is its exceptional durability. Metal edging is typically constructed from materials like steel, aluminum, or iron, all of which are known for their robustness and ability to withstand the elements. Here’s a closer look at the durability aspects of metal edging:

  • Longevity: The longevity of metal edging ensures that your landscaping investments remain intact over the long term, saving you from frequent replacements and maintenance costs. This durability makes metal edging a cost-effective choice in the long run.


Another benefit of metal edging is its versatility. Metal is easily molded to meet your landscape design’s curves and contours, unlike other edging materials. You may build intricate and elegant garden bed, pathway, and other landscaping boundaries using this function. Examples of metal edging flexibility:

  • Curved Flower Beds: Metal edging allows you to create gracefully curved flower beds, giving your garden a more natural and aesthetically pleasing appearance. These curves can mimic the flowing lines of nature, enhancing the overall beauty of your landscape;
  • Tree Rings: You can use metal edging to create circular tree rings around your trees, not only protecting the tree’s roots but also adding a visually appealing element to your garden;
  • Pathway Borders: Metal edging can be customized to define the borders of your pathways, making them look well-defined and organized. This not only adds to the visual appeal but also improves safety by clearly marking walkways.

The ability to shape metal edging to your desired form makes it a versatile choice for various landscaping projects, whether you’re going for a formal garden design or a more organic and flowing layout.

Low Maintenance

One of the significant advantages of using metal edging is its minimal maintenance requirements once installed. Metal edging is inherently low-maintenance for several reasons:

  • Corrosion Resistance: As mentioned earlier, metal edging, especially when coated with protective finishes, is highly resistant to rust and corrosion. This means you don’t have to worry about the edging deteriorating over time due to exposure to moisture or environmental factors;
  • Stability: Metal edging remains stable and in place, reducing the need for constant adjustments or replacements, which can be common with some other edging materials like plastic or wood. This stability ensures that your landscaping features maintain their intended shape and structure;
  • Easy Cleaning: Cleaning metal edging is a straightforward task. You can wipe it down with a damp cloth or hose it off to remove dirt and debris. This simplicity of maintenance allows you to keep your landscaping looking pristine with minimal effort.

The minimal maintenance requirements associated with metal edging free up your time and resources for other aspects of landscaping, making it a practical choice for busy homeowners and landscapers.

Sleek Look

Metal edging offers a sleek and modern aesthetic that can elevate the visual appeal of your landscape. Its clean lines and sharp edges provide a polished and contemporary boundary for your garden beds and other landscape features. This sleek look complements various architectural styles and landscaping designs. Whether you have a traditional garden or a modern outdoor space, metal edging can seamlessly integrate into the overall aesthetics. Benefits of Metal Edging’s Sleek Look:

  • Visual Contrast: Metal edging can create a striking visual contrast with your landscaping materials, such as gravel, mulch, or plants. This contrast can make your garden beds and pathways stand out, enhancing the overall design;
  • Elegance: The sleek and elegant appearance of metal edging adds a touch of sophistication to your outdoor space. It can be particularly appealing in contemporary or minimalist garden designs;
  • Versatile Finishes: Metal edging is available in various finishes, including classic steel, matte black, and even copper. These options allow you to choose a finish that complements your landscape’s color palette and style.

Preparation: Planning Your Design

Before you start installing metal edging for your landscaping project, it’s essential to plan and prepare properly. This phase ensures that your project will be both visually appealing and structurally sound.

  • Measure Your Space: Begin by measuring the area where you intend to install the metal landscape edging. Use a tape measure to get accurate dimensions. Knowing the length required will help you determine how much edging material you need to purchase;
  • Mark the Area: To create a clear outline of where your edging will be placed, lay out a string line or a flexible garden hose along the desired path. This will serve as a visual guide for the installation. Ensure that your design aligns with your landscaping vision;
  • Dig the Trench: Using a spade or a half-moon edger, dig a trench along the line you’ve marked with the string or hose. The trench should be deep enough to accommodate the metal edging while leaving about half of its height exposed above the ground. Make sure the trench is straight and follows the design you’ve outlined.
Trench DepthGuidelines
Recommended DepthApproximately half the height of the metal edging.
ExampleIf you have 6-inch-tall metal edging, aim for a trench depth of about 3 inches.
AdjustmentAdjust the trench depth based on the height of your specific metal edging.
  • Add a Base (Optional): While not always necessary, adding a base material can provide additional stability for your metal landscape edging. Pour a layer of paver base or sand into the trench and then compact it. This base material helps prevent shifting and settling of the edging over time.
Base ThicknessGuidelines
Recommended ThicknessA few inches, typically around 2-3 inches.
AdjustmentAdjust the base thickness as needed based on the stability required for your specific project.

Installation Steps

Now that you’ve prepared the groundwork for your landscaping project, let’s proceed with the detailed installation steps for the best metal edging. Follow these steps carefully to ensure a professional and long-lasting result.

Step 1: Layout the Edging

Laying out the metal edging sections is the initial step to assess the quantity needed and plan for any necessary joins or cuts. Here’s how to do it:

  • Lay out the sections of metal edging along the trench you’ve prepared. This will help you determine if you have enough material for your project and identify where you’ll need to connect pieces or make cuts.

Step 2: Secure the Edging

Securing the metal edging in place is crucial for its stability. Follow these steps:

  • Start at one end of your trench and place a piece of metal edging into it;
  • Use wooden stakes to anchor the edging into the ground. Position these stakes on the inside of curves and every 4-5 feet along straight sections of the edging;
  • Hammer the wooden stakes with a rubber mallet until they are flush with the top of the metal edging. This ensures that the edging is securely anchored.

Step 3: Align the Edging

Achieving a straight and level top edge for the metal edging is essential for a polished appearance. Here’s how to ensure proper alignment:

  • Adjust the depth of the metal edging within the trench to make it even with the ground;
  • Utilize a string line as a guide to verify that the top edge of the edging is perfectly level and straight along its entire length.

Step 4: Connect the Sections

If your landscaping design requires more than one piece of metal edging, you’ll need to connect them appropriately. Typically, this involves one of the following methods:

  • Follow the manufacturer’s instructions for connecting the sections, which usually include sliding the ends together in a channel or using a connector plate.

Step 5: Finish the Installation

Completing the installation involves backfilling the trench with soil to secure the metal edging in place. Follow these steps:

  • Fill the trench with soil;
  • Tamp down the soil firmly against the metal edging to ensure it stays in position.

Step 6: Fine Tuning

After the initial installation is complete, it’s important to make any final adjustments to guarantee the edging is perfectly straight and level:

  • Walk along the installed edging and carefully assess its alignment;
  • If any sections appear uneven or have sharp edges, use a hacksaw or angle grinder to trim them down for a neat and safe finish.

Customization and Tips

When it comes to customizing metal landscape edging for your outdoor projects, there are several key considerations and techniques to ensure a professional and durable result. Here’s a breakdown of customization tips for metal edging:

  • Curves: To accommodate curves in your landscaping design, gently bend the metal edging to match the desired curve. Some metal edging products come with pre-made grooves or flexible sections that make bending easier without causing kinks or damage to the material. Ensure that the bending process is gradual and even to achieve smooth curves in your landscape;
  • Angles: When dealing with sharp corners or angles in your landscaping, it’s essential to create mitered cuts in the metal edging. A mitered angle involves cutting the edging at a precise angle to form a clean and tight corner joint. This technique ensures a seamless and professional appearance, especially in areas where two pieces of edging meet at an angle;
  • Longevity: To maximize the lifespan of your metal landscape edging and protect it from rust, opt for edging with a powder-coated finish. Powder coating is a durable and protective finish that not only enhances the edging’s aesthetics but also provides a strong barrier against corrosion. It is especially crucial for metal edging exposed to outdoor elements and moisture, as it helps maintain the edging’s structural integrity over time. Additionally, routine maintenance, such as cleaning and sealing, can further extend the lifespan of your metal edging.


Metal edging is a sophisticated and practical choice to give your garden that edge of perfection. By following this guide, you will ensure your landscape project has crisp, clean lines and a professional finish that will last for years to come. Remember, the best metal edging for landscaping is one that suits your garden’s needs, both functionally and stylistically. With this durable and attractive solution, your garden edges will look sharp and maintenance will be a breeze, giving you more time to enjoy
