Concrete garden edging runs anywhere from $8 to $35 per meter installed, depending on whether you’re buying precast strips, pouring your own, or hiring someone to do it. The spread is wide because “concrete edging” covers three completely different jobs: snapping together cheap precast pavers, hand-pouring a continuous curb with forms, or paying a contractor to do the latter with proper tools and a finished look. Each has a different failure mode, and the cheapest option is often the right one for small, straight runs.
What you actually pay for
Precast concrete edging strips (the ones that look like scalloped or straight blocks you butt end to end) cost $3 to $8 per meter in materials, plus your time. A 10-meter garden bed border might run $40-80 in materials and an afternoon of labor if the ground is already level. These are fine for straight or gently curved beds where you don’t need a continuous barrier against grass roots or soil erosion.
Poured-in-place concrete edging, where you dig a trench, set wooden or metal forms, and pour ready-mix concrete, costs more in materials ($15-25 per meter including forms, rebar or mesh, and concrete) but gives you a continuous, root-proof barrier. DIY labor adds a full weekend for anything over 15 meters. This is the option that actually stops Bermuda grass or bamboo from invading a bed, which precast strips don’t do well since water and roots find the gaps.
Hiring a contractor to pour edging runs $25-35 per meter in most regions, sometimes more in high labor-cost areas. You’re paying for proper trenching, compaction, correct concrete mix, and a clean finish that won’t crack in the first winter. For anything longer than about 20 meters, or anywhere with slope or drainage concerns, this is usually worth it unless you have real concrete experience.
| Edging type | Cost per meter | Best for | Main failure mode |
|---|---|---|---|
| Precast concrete strips | $3-8 (materials only) | Straight/curved beds, low budget, easy DIY | Gaps let grass and weeds through; heaving in freeze-thaw climates |
| DIY poured concrete | $15-25 (materials + your labor) | Root barriers, driveways, permanent borders | Cracking from poor base prep or no rebar/mesh |
| Contractor-poured concrete | $25-35 (installed) | Long runs, sloped ground, resale-ready finish | Still cracks if contractor skips a gravel base — ask first |
When precast strips are genuinely enough
If you’re edging a flower bed that doesn’t border lawn grass with aggressive runners, precast concrete edging is the right call. It’s also the better choice if you expect to redesign the bed shape in a few years, since you can pull strips up and move them. The main complaint I hear is edging “walking” out of the ground after a hard winter. That’s almost always a installation problem, not a product problem: the strips need to sit on a few centimeters of compacted gravel or sand, not loose topsoil, or frost heave will push them up every year.
Don’t buy the thinnest precast strips you find at a big box store if your soil has any clay content. Clay swells when wet and will crack thin edging within two seasons. Spend a little more for strips rated at least 4-5 cm thick.
What poured edging actually requires
If you’re pouring your own, budget for a trench 10-15 cm deep and about 10 cm wide, a layer of compacted gravel base, wooden or flexible plastic forms, and either rebar or a strip of welded wire mesh down the center. Skipping the base is the single most common reason DIY poured edging cracks in the first year — concrete over soft, uncompacted soil moves with the ground and cracks along the weak point, which is usually every meter or so where there’s no reinforcement.
For mixing and placing concrete over any real distance, a basic concrete mixer makes the job survivable; hand-mixing bag after bag of ready-mix in a wheelbarrow for a 15-meter run is miserable and the mix quality gets inconsistent toward the end. If you’re doing this yourself, it’s worth looking at a concrete mixer rental or small electric unit rather than mixing by hand. You’ll also want a basic concrete edging tool to round off the top edge so it doesn’t chip, and a decent trowel set for finishing the surface smooth.
What you need for precast installation
Installing precast strips is simpler but still needs a trench and a flat, compacted base, or the pieces will rock and separate at the joints within a year. A flat spade or edging trencher speeds up cutting a clean trench line, especially on long curved borders where a straight spade fights you on the curve.
Costs people forget to budget
Base material (gravel or sand) adds roughly $2-4 per meter that often doesn’t show up in a quoted “concrete edging” price, whether DIY or contractor. Removing old edging, if you’re replacing something, is another cost that catches people off guard: pulling up decades-old concrete curbing can take longer than installing the new edging. If your contractor’s quote doesn’t mention base prep or demo of existing material, ask directly, because that’s where corners get cut and where edging fails fastest.
Climate matters more than most quotes acknowledge. In regions with hard freeze-thaw cycles, unreinforced poured concrete edging without a proper gravel base will crack within two or three winters regardless of who pours it. If you’re in that kind of climate and not willing to pay for a contractor who does it right, precast strips that can be reset or replaced individually are often the more practical long-term choice, even though they look less seamless.
