Metal edging is a crucial component in landscaping and garden design, providing both aesthetic appeal and functional boundaries. As a professional in the field, maintaining metal edging is key to ensuring longevity and optimal performance.

Here are some comprehensive maintenance tips tailored for professionals.

Metal Edging Regular Inspection and Cleaning

Inspect Metal Edging Regularly

Regular inspections are fundamental to catching potential issues early. Schedule inspections monthly or bi-monthly, depending on the environment and usage.

During inspections, check for any signs of wear, rust, or damage. Pay close attention to the areas where the edging is most exposed to moisture or heavy use, such as garden beds near sprinklers or paths that experience a lot of foot traffic.

Clean Thoroughly

Thorough cleaning should be part of your routine maintenance. Dirt, debris, and organic matter can accelerate rust and corrosion.

Use a stiff-bristled brush to scrub the surface of the metal edging. For more stubborn grime, a solution of mild soap and water can be effective. Rinse thoroughly and allow it to dry completely to prevent any moisture buildup.

Metal Edging Rust Prevention

Apply Protective Coatings

Applying a protective coating is one of the best ways to prevent rust. Use a rust-inhibiting primer or paint specifically designed for metal. These products create a barrier that prevents moisture from reaching the metal surface. Ensure the coating is evenly applied and cover all edges and corners, which are more prone to rust.

Use Galvanised or Stainless Steel

When installing new metal edging, recommend using galvanised or stainless steel. These materials are inherently more resistant to rust due to their protective zinc coating (in the case of galvanised steel) or their chromium content (in stainless steel). Although they may have a higher upfront cost, the reduced maintenance and longer lifespan can provide significant savings over time.

Metal Edging Addressing Corrosion

Remove Rust

If rust is present, it's essential to remove it promptly. Use a wire brush, sandpaper, or a power tool designed for rust removal to scrub off the rust. After removing the rust, apply a rust converter to stabilize the remaining material and prevent further oxidation. Finish by applying a fresh coat of protective paint or primer. 

Replace Severely Corroded Sections

For sections that are heavily corroded and beyond repair, replacement is often the best option. Cut out the damaged section carefully to avoid damaging surrounding areas. Install a new piece of metal edging, ensuring it is securely anchored and properly treated to prevent future corrosion.

Metal Edging Managing Environmental Factors

Control Moisture around Metal Edging

Controlling moisture around metal edging is crucial for preventing rust. Ensure proper drainage by grading the soil away from the edging and installing drainage systems if necessary. In areas with high rainfall or heavy irrigation, consider installing gravel beds or other permeable materials around the edging to facilitate water drainage.

Avoid Metal Edging Chemical Exposure

Certain chemicals, such as fertilizers and herbicides, can accelerate the corrosion process. Advise clients to use organic or less aggressive alternatives. If chemical use is unavoidable, make sure to rinse the metal edging thoroughly to remove any residues.

Check for Metal Edging Stability

Over time, metal edging can become loose due to soil movement, freeze-thaw cycles, or physical impact. Regularly check that the edging is firmly anchored and has not shifted. Re-secure any loose sections with additional stakes or anchors as needed to maintain a straight and even boundary. 

Reinforce Weak Metal Edging Points

Certain areas of the edging may be more prone to damage, such as corners or joints. Reinforce these weak points with extra stakes or supports. Additionally, consider using thicker or more durable edging material in high-stress areas to prevent bending or warping.

Metal Edging Seasonal Maintenance

Prepare Metal Edging for Winter

Winter conditions can be particularly harsh on metal edging. Before the onset of cold weather, clean and inspect the edging, and apply a fresh coat of protective paint if needed. Ensure the edging is free of any debris that could trap moisture and cause rust during freeze-thaw cycles.

Metal Edging Spring Check-Up

After winter, conduct a thorough inspection to assess any damage caused by frost heave, heavy snow, or ice. Look for any signs of rust, bending, or displacement. Address any issues immediately to prevent further deterioration during the growing season.

Metal Edging Regular Upkeep

Routine Metal Edging Touch-Ups

Small scratches or exposed areas can quickly turn into rust spots if not addressed. Periodically inspect the edging for any signs of damage and touch up with protective paint or primer as needed. This simple maintenance step can significantly extend the life of the metal edging.

Keep Surroundings Clear

Vegetation can trap moisture and debris against the metal, promoting rust. Regularly trim grass and plants around the edging to keep it clear. Use a string trimmer or garden shears to maintain a clean edge and prevent overgrowth.

Professional Tools and Products

Use Quality Products

Investing in high-quality tools and maintenance products is crucial for effective upkeep. Use professional-grade rust removers, protective coatings, and cleaning equipment. High-quality products ensure better performance and durability, ultimately saving time and money in the long run.

Follow Metal Edging Manufacturer Guidelines

Every type of metal edging may have specific maintenance requirements. Always follow the manufacturer’s guidelines for maintenance and care. This ensures that you’re using the correct products and techniques, maintaining the integrity and warranty of the edging.
