The Essential Buying Guide for Metal Garden Edging
Metal garden edging is a fantastic way to give your yard a neat, clean, and professional look. It keeps mulch in place and stops grass from creeping into your flower beds. Choosing the right edging can be tricky, so this guide will help you find the best fit for your garden.
1. Key Features to Look For
When shopping for metal edging, keep these important features in mind. They make a big difference in how long your edging lasts and how easy it is to use.
Height and Depth
- Height: Choose a height that works for your needs. Taller edging (6 inches or more) works well if you have deep mulch layers or need strong separation between a lawn and a garden path. Shorter edging (3-4 inches) is good for light separation.
- Depth (For burying): Some styles need to be buried partially. Make sure the edging is deep enough to hold firm against soil pressure.
Connection System
How do the pieces connect? Look for strong connection methods. Some use simple overlapping joints, while others use internal clips or screws. Strong connections prevent gaps from forming over time.
Flexibility
Do you want straight lines or curvy flower beds? Flexible metal edging lets you create smooth curves easily. Stiffer sections are better for very straight paths.
2. Important Materials: What Your Edging Is Made Of
The material determines the look, strength, and price of your edging.
Steel
- Galvanized Steel: This is the most common choice. Zinc coats the steel, which stops rust. It offers a good balance of strength and cost.
- Corten Steel (Weathering Steel): This material forms a stable, rust-like surface layer after exposure to weather. This layer protects the inner metal from further rusting. It gives a beautiful, rustic look.
Aluminum
Aluminum is naturally rust-proof, so it lasts a very long time, especially near water or in damp soil. It is usually lighter than steel, making it easier to install. However, it might bend more easily if hit hard.
Thickness (Gauge)
Thickness is very important for quality. Thicker metal (lower gauge number) means stronger edging. Thin metal bends easily and might not hold back aggressive grass roots. Aim for at least 18-gauge steel for good durability.
3. Factors That Improve or Reduce Quality
Quality isn’t just about the base material; the finish matters too.
Coatings and Finishes
A good powder coating adds a layer of protection against scratches and moisture. This finish keeps the metal looking good longer. Poorly painted or uncoated metal will rust much faster.
Installation Stakes
Most metal edging needs stakes to hold it down. Check what kind of stakes come with the product. Heavy-duty, long stakes secure the edging much better than short, flimsy ones. Good stakes prevent the edging from popping up in the heat.
Ease of Installation
Some edging comes in long, continuous rolls that you just unroll and stake down. This saves a lot of time. Others come in short, rigid panels that require careful alignment and connection. Simpler systems usually mean a better user experience.
4. User Experience and Use Cases
Think about how you plan to use the edging in your yard.
Defining Garden Beds
This is the most common use. Metal edging creates a sharp line between your lawn and planting areas. This makes mowing easier because the mower wheel can run right along the top edge.
Containing Hardscaping Materials
Use sturdy metal edging to hold back gravel paths or decorative stone mulch. The metal prevents these materials from spilling onto the grass.
Root Barriers
If installed deep enough (often 10 inches or more), some metal edging can act as a root barrier, stopping aggressive plants like bamboo or certain trees from spreading into unwanted areas.
10 Frequently Asked Questions (FAQ) About Metal Garden Edging
Q: Will metal garden edging rust?
A: Galvanized steel edging resists rust well because of its zinc coating. Aluminum will not rust at all. Corten steel is designed to rust on the surface but this rust layer protects the rest of the metal.
Q: How deep should I bury the edging?
A: For basic definition, burying 1 to 2 inches is enough. For strong root control, you might need to bury 6 to 12 inches, depending on the plant.
Q: Is metal edging difficult to install?
A: No, most modern metal edging is quite easy to install. You usually unroll it and tap the included stakes into the ground with a rubber mallet.
Q: Can I use metal edging for curves?
A: Yes! Most flexible metal edging is designed to bend smoothly around tight curves without kinking, provided you install it slowly.
Q: What is the difference between steel and aluminum edging?
A: Steel is generally stronger and heavier, offering better resistance to being pushed. Aluminum is lighter, easier to handle, and naturally rust-proof.
Q: How do I join two pieces of edging together?
A: Manufacturers provide specific connectors, usually metal sleeves, clips, or screws, to overlap and tightly secure the ends of two sections.
Q: Will the sun make the metal too hot for plants?
A: While metal absorbs heat, the small amount of heat transferred to the surrounding soil is usually not enough to harm established plants.
Q: Does metal edging stop aggressive weeds?
A: It stops runners like Bermuda grass from crossing over, but it does not stop seeds dropped on top of the soil from sprouting near the edge.
Q: What is the best gauge for durable edging?
A: For excellent durability that resists bending from lawnmowers or shovels, look for 18-gauge steel or thicker.
Q: Can I paint my metal edging?
A: Yes, if you want a color other than metal gray or rust brown. You must use a metal primer first, and then apply paint formulated for outdoor use.
