The best steel edging infrequently asked questions

21 January 2024

If you are a garden designer or landscaper, or even if you are simply passionate about your outdoor space, you will appreciate how the nuances of different materials and their applications in a garden can lead to a variety of inquiries and questions. To celebrate the New Year, we’re delving into some of the less common questions to have hit EverEdge NZ’s inbox in 2023.


Is Corten garden edging suitable for a coastal garden

If you live on the coast, you will be aware of how humidity, salt and wind impact your home and garden and accelerates degradation. Corten steel edging is renowned for its weather-resistant properties, making it an ideal choice for coastal gardens in NZ. Its ability to withstand the salty air and retain its structural integrity makes it a go-to option for garden bed edging in these environments. Not only does it resist corrosion, but its rustic appearance adds a stylish touch to seaside gardens.


Do metal tree ring edging products limit tree growth?

It depends how you use it! As trees mature the ground underneath gets shady and consequently bare. Some people install a tree ring to create a flowerbed border for planting shrubs under the canopy, this is a one-way ticket to damaging your tree. If you love your tree, don’t plant anything underneath it.


Tree roots are surprisingly close to the surface, so digging, planting and filling the ring with soil in this area risks upsetting the oxygen exchange that the tree needs to be healthy. Metal tree edging provides a protective border around your trees enabling essential water and nutrients to reach the roots, so they flourish without restriction. If you want to cover the bare ground, mulch is the solution. Remember to keep the base of the tree exposed (applied like a doughnut) to allow the tree to breathe and avoid bark rot. Mulch should be no more than 3-4 inches thick, or 2 inches if the soil drains poorly (e.g. clay heavy soil).

Can metal landscape edging be installed on winding paths?

A common misconception is that landscape edging can only be applied in straight lines. Whether you have a conventional rectangular garden design or a whimsically shaped landscape design, metal landscape edging can be tailored to fit. Garden edging NZ products, especially steel edging, are incredibly versatile so, whether your garden curves left or right, or even zigzags, steel edging is the solution for your garden design.


Steel garden ornaments rust away, does this happen to steel garden edging?

Steel garden ornaments are typically made from a thin gauge mild steel because it’s easy to cut and create intricate details. This type of steel left untreated is not designed to be outside and exposed to the elements, so as it begins to rust, its degradation can be quick. This is why EverEdge Classic metal edging is galvanised and powder coated. Galvanisation increases the mild steel’s surface strength by an additional 13%, so the product becomes incredibly strong and durable while protecting the steel from oxidisation (rust).


Alternatively, Cor-Ten steel landscape edging is designed to gain strength from being exposed to the atmosphere. Both the Classic and Cor-Ten ranges remain incredibly strong, resilient and durable for many years. You can learn more by clicking here.

Creating definition between a lawn and garden beds is one of those seemingly small details that makes an enormous difference to the overall aesthetic of an outdoor space. A well-defined edge transforms a garden from casual to sophisticated, providing clean lines that elevate planting schemes while making maintenance significantly easier. Why garden edges matter Garden edges create visual boundaries that guide the eye and bring structure to your landscape. Beyond aesthetics, quality garden edging prevents grass from encroaching into beds, keeps mulch and soil in place, and simplifies mowing. Without proper landscape edging, gardens can quickly develop that dreaded unruly and unkempt look that requires constant attention. Material matters: the case for steel There are many edging options, from traditional brick to temporary plastic, but steel landscape edging stands in a class of its own for durability and clean definition. Unlike wooden edges that rot or concrete that cracks, metal landscape edging provides a permanent solution that ages beautifully. EverEdge steel garden edging offers the perfect combination of flexibility and strength. Whether you're creating straight formal lines or gentle curves, steel edging maintains its shape year after year, withstanding seasonal shifts and gardening activities. For contemporary gardens, Corten steel edging brings an added dimension with its rich, rust-coloured patina that develops naturally over time.
