Plastic or metal garden edging in Australia?

Plastic is flexible and budget-friendly for curves; metal holds straight lines and resists lawn encroachment longer.

How deep should garden edging sit?

Enough to block runners — typically several centimetres buried with a clean top edge for mowing; follow the product’s spike or trench guide.

Can I install edging without digging?

Yes — many spiked no-dig rolls work in soft beds; heavy clay or high traffic still benefits from a shallow trench.

Will metal edging rust?

Prefer aluminium or coated steel outdoors; rinse salt in coastal gardens and avoid burying untreated mild steel.

Edging vs raised garden beds?

Edging defines lawn/bed lines at ground level; raised beds add soil height — use edging when you only need a crisp border.

1. Plastic vs metal garden edging

Flexible plastic rolls suit curved beds and DIY weekends; steel or aluminium packs give crisp straight lines and lasting lawn edges under mower wheels.

2. No-dig vs trenched install

No-dig spike systems are fast for soft soil; trench-in metal edging resists lawn creep better on clay and high-traffic paths.

3. Heights and mower clearance

Choose height for soil retention vs a low bevel for whipper-snipper and mower edges. Leave a clean mow strip so grass doesn’t overgrow the border.

4. UV, rust and Aussie soils

UV-stable plastics and rust-resistant metals matter in full sun. Rinse coastal installs and avoid untreated mild steel against wet soil.
