In this guide, we’ll compare the pros, cons, costs, and durability of each type, helping Sydney homeowners select the perfect garden edging for their landscaping projects.

3. Stone & Brick Garden Edging (Sandstone, Bluestone, Brick Pavers)

Best for: Classic, natural, and high-end Sydney landscapes

✅ Pros:

  • Timeless aesthetic – Perfect for heritage homes & bushland gardens

  • Extremely durable – Lasts decades with minimal upkeep

Stone & Brick Garden Edging

Best Uses in Sydney:
✔ Heritage homes in North Shore & Northern Beaches
✔ Bushland-style gardens in Upper North Shore
✔ High-end properties needing a luxury finish

Popular Sydney Stone Choices:

  • Sydney sandstone blocks (local & iconic)

  • Bluestone pavers (modern & sleek)

  • Exposed aggregate edging (durable & slip-resistant)

Which Garden Edging is Best for Sydney’s Climate?

Sydney’s humid summers, coastal salt air, and occasional heavy rains mean your edging must withstand:
✔ UV exposure (plastic can fade, metal can heat up)
✔ Moisture & erosion (stone is best for drainage)
✔ Soil shifts (metal & stone handle movement better)

Best by Climate Zone:

  • Coastal areas (Bondi, Manly): Powder-coated metal (rust-resistant)

  • Western Sydney (Parramatta, Penrith): Stone or thick plastic (heat-resistant)

  • Bushfire-prone areas (Blue Mountains): Steel or stone (non-flammable)

Cost Comparison: Metal vs. Plastic vs. Stone Edging in Sydney

Material Avg. Cost per Metre (AUD) Lifespan Maintenance
Metal $25 – $60 20+ yrs Low
Plastic $5 – $20 5–10 yrs Medium
Stone $50 – $150+ 30+ yrs Low

Tip: For budget-friendly stone options, consider reclaimed bricks or broken concrete (“urban stone”).

Final Verdict: Which Garden Edging is Best?

  • Best Premium Choice: Metal (Corten steel or aluminium) – Sleek, durable & modern

  • Best Budget Choice: Plastic (recycled or no-dig) – Affordable & easy to install
