Grow garden grow: Metal edging to boost plant health

24 August 2022

Without a doubt garden bed edging enhances the aesthetic appeal of any garden or lawn. A neat and orderly landscape not only looks great, but it also benefits the plants, shrubs, and trees. This is a lesser-known benefit of using steel landscape edging.

Garden edging has been used for centuries to enhance the appearance of a garden and outdoor space. However, it also has significant benefits for the health of the garden beyond just aesthetics. Garden edging products deliver an instant polished look, but the effect on plant health also delivers long-term benefits.

How metal edging helps garden plant health

EverEdge has been a leading manufacturer of metal edging for over 25 years. It’s easy to see why our steel garden edging goods boosted the transformation of NZ gardens, making them more beautiful and longer lasting.

Garden edging reduces material loss

As a keen gardener, you are most likely familiar with mulches. Mulches are loose coverings spread on top of the ground to conserve water, stop weeds, reduce the amount of work needed and enhance the soil quality.

The downside of mulching is it escapes from the bed and leeches onto the lawn. Garden bed edging keeps the mulch in position giving the garden a neat appearance but also helping the flora to flourish and thrive.

Metal tree ring edging protects trees

Tree edging transforms a tree into a manicured and clean feature, but it also defines a safe zone around the tree trunk. Trees rely on efficient movement of water and nutrients between their roots and top growth for fruiting and flowering. However, damage to the bark can disrupt this essential sap flow, preventing the tree from being healthy. When bark is damaged it becomes exposed and vulnerable to infection, dieback or even the premature death of the tree.

A garden ring around the tree guards it from harm caused by lawn mowers and trimmers while cutting the grass nearby. Garden rings are hardy to garden machinery and are the only true way to protect trees.

Metal landscape edging maintains flowerbeds

The nemesis of every gardener are weeds. Plants that sprout in undesired areas are known as weeds, particularly grass, which is difficult to manage. The vegetation you want to grow must battle with the weeds for water and soil nutrients.

Garden bed edging prevents grass from encroaching on flowerbeds and eroding their structure and form. With restricted grass growth, the soil’s nutrients are more available to the plants you intend to grow, encouraging new growth and plant health. A healthy garden is a beautiful garden, and its beauty is paramount to helping you achieve your garden goals and create an abundant space you enjoy.

EverEdge combines the traditional practice of garden edging with modern advancements, including the feature of quick and easy installation. This allows for greater flexibility in creating custom shapes, while still being durable and long-lasting.

The gardener’s guide to avoid garden edging mistakes

by Simon Mullinger • 25 August 2025

A well-designed garden isn’t just about the plants you choose; it’s the finishing touches that make all the difference. Garden edging frames your beds, pathways, and lawns, creating a clean, structured look while keeping soil, mulch, and grass exactly where they should be. But despite its time-saving capabilities, small mistakes during planning or installation can leave you with an untidy or high-maintenance garden – exactly what you didn’t sign up for. As a supplier of the best high-quality steel landscape edging products in New Zealand , EverEdge has heard it all – from shallow installs that allow grass to creep back in, to cracked or warped materials that ruin a carefully designed border. To help you get it right the first time, here are the top three garden edging mistakes and how you can avoid them. 1. Choosing the wrong edging material One of the most common mistakes is selecting edging that doesn’t stand the test of time. Plastic and timber edging might look appealing initially, but they deteriorate quickly over time, accelerated by harsh weather. Plastic warps under the sun, while timber is prone to rotting and shifting. Both often require replacement within just a few seasons. Even if you opt for the more expensive concrete garden edging it is vulnerable to ground movement and freeze-thaw cycles. By contrast, metal landscape edging, particularly steel garden edging, offers durability, flexibility, and a clean aesthetic. It can be shaped into sweeping curves or sharp angles without cracking, and it resists corrosion for decades. EverEdge products are designed for professional results and are trusted by landscapers across New Zealand for everything from garden bed edging and metal tree ring edging to driveway edging. Choosing a long-lasting material from the outset saves you time, money, and endless frustration down the line. 2. Installing at the wrong depth Even the best edging material won’t perform if it’s not installed correctly . A frequent error is laying edging too shallow. This allows mulch and soil to spill over and gives grass and weeds the perfect opportunity to creep back into your beds. Too deep, on the other hand, and the edging becomes buried, disappearing from sight and failing to give that crisp separation between lawn and border.
