What are the best edging options for garden beds in New Brunswick?

The best garden bed edging options for New Brunswick include aluminum or steel landscape edging, natural stone, and concrete curbing — materials that withstand the province's freeze-thaw cycles, heavy snow loads, and wet Maritime conditions without shifting, rotting, or crumbling. Cheap plastic edging sold at garden centres is the most common choice and the most common failure in NB's climate.

Aluminum landscape edging (brands like Sure-Loc or Permaloc) is the professional's choice for NB garden beds. It's thin (1/8 inch), virtually invisible once mulch is applied, and stays rigid through freeze-thaw cycles that warp and pop plastic edging out of the ground. Aluminum won't rot, rust, or degrade from moisture exposure — critical in NB's 1,100–1,200mm annual rainfall climate. It installs with stakes driven into compacted soil every 3–4 feet and bends smoothly around curves. Professional-grade aluminum edging costs $3 to $6 per linear foot installed and lasts essentially forever.

Steel landscape edging is similar to aluminum but heavier-gauge and even more rigid. It's ideal for straight lines and sharp geometric bed edges. Cor-ten steel (weathering steel) develops an attractive rust patina that complements natural NB landscapes. Standard steel will rust through eventually, but quality landscape-grade steel edging lasts 15–20 years in NB conditions. Steel edging costs $4 to $8 per linear foot installed.

Natural stone edging creates a substantial, visible border that doubles as a design element. Flat fieldstone set vertically or slightly angled creates a rustic NB aesthetic. Granite cobblestones (4x4 or 6x6 inch cubes) set in a concrete footing create a formal, permanent edge. The key in NB is setting stone edging on a 4-inch compacted gravel base so frost heave shifts the entire edge uniformly rather than popping individual stones. Natural stone edging costs $8 to $15 per linear foot installed depending on the stone type and setting method.

Concrete curbing (continuous poured-in-place edging) creates a clean, permanent border. A machine extrudes the concrete into a consistent profile along your bed edge. It's popular in NB for its clean look and permanence, though it can crack if the base isn't properly prepared for freeze-thaw movement. Concrete curbing costs $5 to $10 per linear foot and typically lasts 10–20 years in NB before cracks develop.

Avoid these materials in NB. Thin plastic roll edging warps and pops out of frozen ground every winter — you'll reinstall it every spring. Untreated wood edging rots within 2–3 years in NB's wet climate. Rubber edging degrades from UV exposure and becomes brittle in cold temperatures. Even pressure-treated wood timbers, while lasting longer (8–12 years), eventually rot and shift with frost heave.

For a typical NB home with 100–200 linear feet of garden bed edging, budget $300 to $1,200 for quality aluminum or steel edging installed, or $800 to $3,000 for natural stone. The investment pays for itself by eliminating the annual grass-creeping and edge-repair cycle that cheap edging creates.
