9 Ways To Edge Your Garden Beds

There are many types of garden edging to choose from, so there's no surprise if you are overwhelmed. We've tried to make it easy by breaking down the pros and cons of the varieties to choose from.

Why You Need Garden Edging

There are many reasons why you should consider garden edging. Garden edging will not only improve the aesthetic of your garden, but it will also make maintenance tasks trouble-free and more efficient.

For garden beds nearing grass, edging separates the grass and the mulch. It creates crisp, clean cut lawn edges that makes mowing simple. Without separation, grass will continue to grow and creep into the garden bed, making your beds look untidy.

Garden edging adds a design element into your outdoor space. Edging delineates the garden beds from hardscaped or lawn areas. It looks smart and stylish whilst also creating distinct garden spaces.  A well designed garden not only adds value to your home but also reduces garden maintenance tasks.

Corten Steel

Corten Steel is currently my personal favourite option for garden edging. 

The industrial look is trending, which has seen a rise in the use of corten steel in gardens.  When used in landscaping, corten steel adds interest and texture due to its natural weathering rustic look


  • Excellent quality

  • Tested strength

  • Long life span

  • 100% recyclable

  • Highly resistant to weather 

  • Excellently withstands corrosion

  • Production requires less water & energy 

  • Attractive in style and function 

  • No need for paint

  • Very little maintenance

  • Can create attractive curved beds


  • It is not entirely rustproof. If the steel never had a chance to dry out, it may cause corrosion. This is more likely to happen in gardens with poor drainage or in humid climates. 

  • Rust can stain nearby areas, such as tiles or concrete.  Most suppliers will offer steel that has had a pre-weathering treatment to reduce the amount of "bleeding" between 6 months to two years. After that, the steel should have developed its protective layer, helping to prevent staining. 

We can recommend Tiny Anvil for Corten Steel.

Timber can be attractive in the right landscape, as it blends in and gives a natural feel. 


  • Timber edging is relatively cheap & easy to install


  • Wood will eventually rot so opt for treated timber.
  • Requires painting or staining and future maintenance to help withstand the environment

Railway Sleeper Edging

Railway sleeper edging is made from large rectangular timber slabs, and are an ideal cost-efficient option for creating a raised garden beds. Sleepers are a timeless way of making your garden look elegant.


  • Last longer than pegged timber
  • Good insulating properties for vibration and noise
  • Easy to install and maintain
  • Can be replaced when rotten


  • Treated sleepers are not suitable for vegetable beds where the chemicals can leech into the produce - use untreated macrocarpa as an alternative.
  • Can't create curved edges.
