Steel edging — the crisp line
The designer's default: a thin, continuous line that curves beautifully and disappears into the design. Raw steel develops a rust patina (a feature, not a fault); powder-coated stays black. Decades of life in Perth sand, mid-range cost, and easier DIY than it looks — the pins do the work.
Timber and sleeper edging — warm and natural
Timber suits native and cottage gardens and doubles as a low raised-bed wall in sleeper form. In ground contact it's a 5–8 year finish even treated — accept that or choose concrete 'timber-look' sleepers for the same style with triple the life.
Flexible poly edging — curves on a budget
The budget shape-maker: bends to tight curves, invisible once the garden grows in, and the easiest DIY of all. It won't hold back much soil, so use it as a mowing edge and pebble-stopper, not a retaining product.
Limestone and paver edging — the Perth classic
Limestone block edging matches half the walls in Perth and makes a bed feel built, not just planted. Heavier DIY (a levelled sand bed matters) but effectively permanent, and small-format blocks are stocked in store.
Which edging for which garden
Whatever you choose, weed mat under any stone or gravel beside the edge keeps the line clean for years — the edging and the mat are a team.
- Crisp modern lines and curves → steel
- Native / cottage warmth → timber or lupin-mulched steel
- Tight budgets and tight curves → flexible poly
- Matching Perth limestone walls → small-format limestone
- Raised bed + edge in one → sleepers
