Types of Metal Garden Edging

Steel Edging

  • Materials: Typically made from galvanized steel or corten steel.
  • Advantages: Extremely durable, resistant to corrosion (especially corten steel), and provides a strong barrier.
  • Disadvantages: Can be heavy and more challenging to install, may rust if not properly treated (galvanized steel).

Aluminum Edging

  • Materials: Made from lightweight aluminum.
  • Advantages: Lightweight, easy to install, resistant to rust and corrosion, and available in various finishes.
  • Disadvantages: Not as strong as steel, can bend or dent under heavy impact.

Corten Steel Edging

  • Materials: Made from weathering steel that develops a rust-like appearance over time.
  • Advantages: Highly durable, unique aesthetic appeal, and resistant to atmospheric corrosion.
  • Disadvantages: More expensive than other types of metal edging, the rusting process can stain nearby surfaces.

Powder-Coated Metal Edging

  • Materials: Steel or aluminum with a powder-coated finish.
  • Advantages: Available in various colors, added layer of protection against corrosion, and aesthetically versatile.
  • Disadvantages: Coating can chip or scratch over time, which may expose the metal to rust.

Choosing the Right Metal Garden Edging

Consider the Garden Style

  • Match the edging material with the overall style of your garden. Modern gardens may benefit from sleek aluminum, while rustic or industrial designs might prefer Corten steel.

Durability and Maintenance

  • Choose materials that will withstand your local climate and garden conditions. Steel and Corten steel are ideal for areas with harsh weather conditions.

Cost and Budget

  • Determine your budget and explore options within your price range. While Corten steel may have a higher upfront cost, its long lifespan can make it a cost-effective choice in the long run.

Ease of Installation

  • Some metal edgings are easier to install than others. Aluminum is lightweight and typically easier to work with, while steel may require more effort and tools.

Installation of Metal Garden Edging

Planning and Preparation

  • Outline the Areas: Plan where you want to install metal garden edging. Use a garden hose or string to outline the areas you want to edge.
  • Measure the Required Length: Measure the perimeter of the areas to determine how much edging material you will need.
  • Choose Your Edging Material: Select the appropriate metal edging based on your garden style, durability, and budget.

Tools and Materials Needed

  • Metal edging (steel, aluminum, or Corten steel)
  • Spade or trenching tool
  • Level
  • Stakes and string
  • Rubber mallet or hammer
  • Measuring tape
  • Metal snips or a hacksaw (for cutting edging)
  • Safety gloves
  • Screws or metal stakes (for securing edging)

Step-by-Step Installation Guide

  1. Mark the Area: Use stakes and string to outline where the edging will go. Ensure the lines are straight or follow the desired curves.
  2. Dig a Trench: Dig a trench along the marked line, deep enough to accommodate the metal edging. The depth will depend on the height of the edging material.
  3. Prepare the Base: Add a layer of sand or gravel to the bottom of the trench to create a stable base for the edging. Compact it to ensure a level surface.
  4. Place the Edging: Place the metal edging into the trench. Ensure it’s level and aligns with your design. For longer runs, connect multiple pieces using screws or metal stakes.
  5. Secure the Edging: Use a rubber mallet or hammer to tap the edging into place. Ensure it’s firmly anchored in the ground.
  6. Backfill the Trench: Backfill the trench with soil or mulch, compacting it around the edging to provide additional stability.
  7. Final Touches: Ensure everything is secure and stable. Adjust the edging as necessary to achieve the desired look and function.

  • Weed Control: Periodically check for weeds that may be growing near the edging and remove them to prevent them from spreading into your garden beds.

Repair and Replacement Tips

  • Prompt Repairs: Promptly repair any damaged sections to prevent further deterioration. Small bends can often be straightened with pliers or a mallet.
  • Replacement: Replace edging materials that are beyond repair to maintain the integrity and appearance of your garden. For extensive damage, consider replacing entire sections rather than just the damaged part to ensure uniformity.
