The best landscape edging for most flower beds and borders is steel, and the choice within steel comes down to one number nobody advertises: how deep it buries. A $2 a foot hammer-in kit puts about three inches in the ground. A six inch Cor-Ten strip at about $6.50 a foot puts in twice that, and that is the one that actually holds grass back.
Worth saying plainly before the list starts: edging does not have to be a product. The oldest and best looking border in landscaping is a trench cut into the soil with a spade, and it is what most of the estate gardens you have admired actually use. Everything else on this page is a way to make that line hold with less maintenance.
Which is the real decision. University of Illinois Extension puts it plainly: grass grows toward and into beds about three to four inches a year. So the honest question is not "which edging works" but how much of that creep you are willing to fight, and how often. A trench edge asks for twenty minutes once or twice a season. Six inches of steel asks for almost nothing for twenty years, and asks for the money up front.
One thing before the list: we make digging tools, so the spade in idea one is ours and we say so. Every edging material below is somebody else's product.

What is the best landscape edging?
Steel, for most yards. It is the only cheap material that is simultaneously thin enough to disappear, stiff enough to hold a straight run, and flexible enough to take a curve. But read the buried depth before you read the price, because most hammer-in kits put only about three inches in the ground, and three inches slows grass rather than stopping it. If you want a barrier at the depth extension sources actually recommend, buy a strip that states six inches and pay about three times as much per foot for it.
If budget decides it, no-dig plastic coil is the cheapest thing that works, at roughly a quarter of the cost of the cheapest steel. If you want the border to look like it grew there, cut a trench edge and skip the product entirely.
What should you look for in landscaping edging?
Five things separate edging that holds for a decade from edging that heaves out of the ground in the second spring.
- Buried depth is what actually stops grass. Height above grade is cosmetic. What blocks turf is the part below the soil line, because grasses spread by rhizomes and stolons that travel horizontally a few inches down. University of Illinois Extension puts the threshold at four inches, noting that an edge four inches deep and wide can easily contain bluegrass. Aggressive spreaders are a different story: bermudagrass rhizomes are usually in the top one to six inches but have been recorded far deeper, and quackgrass shoots come up from rhizomes at ten inches or more, which is why no edging is a permanent fix against either.
- The top profile decides whether you can mow it. A flat top set level with the turf lets a mower wheel ride straight over the border and cuts your string-trimming to nothing. A rolled or decorative top looks better and commits you to trimming by hand.
- Stake count, not stake length. Frost heave pushes edging up, and stakes are what hold it down. Count the stakes against the footage: the galvanized steel kit ships 11 stakes for 33 feet, the aluminum kit 36 for 72 feet, the composite 24 for 40, the pound-in poly 6 for 20, and the no-dig plastic 50 spiral spikes for 40 because thin plastic needs far more anchoring than steel does. If a kit ships light, a bag of 50 ten inch landscape anchoring spikes is about $24 and works for paver restraint, turf, and weed fabric too.
- Thickness and gauge over marketing. Thin steel dents when you catch it with a mower deck and thin plastic goes wavy in July sun. This is the spec listings are quietest about. Gauge, when it is stated at all, is the number to look for: 16-gauge steel is substantially heavier than the unstated stock in a budget kit.
- How it takes a curve. Steel and plastic coil bend freely. Composite and rubber sections bend to a limit and then kink. Brick, stone, and log rolls do not bend at all, so a tight curve becomes a series of short straight facets with gaps that grass finds.
The 13 landscape edging ideas, by job
Ordered by how often they are the right answer, not by price.
1. Spade-cut trench edge: the best looking garden border edging, and free
A trench edge is a V or an L cut into the soil at the bed line: a vertical face on the lawn side, a shallow slope back into the mulch, and no material at all. It is the border every other one on this list is imitating. It follows any curve exactly, costs nothing, never heaves, never fades, and can be moved in an afternoon when you change the bed shape. It is also the only entry here whose depth is entirely up to you, which means it is the only one that can be cut deeper than six inches without buying anything.
What it costs you is a recut, at least once a year and twice if you want it crisp through the whole season. Cutting it is a spade job rather than a shovel job, because you want a straight vertical slice and a lifted wedge, not a scoop. Our D-handle Spear Head Spade is built for that cut: the double-patented blade is pointed and sharpened like a spade but curved like a shovel, so the same tool slices the line, makes the relief cut, and carries the wedge out without you swapping tools. It is also the tool the bed already needs for planting, which is why a trench edge is the only idea here that adds nothing to the shed.
Not sure which of our spades suits your height and soil, take the two minute spade finder. For the technique itself, string line to finished trench, we wrote it up step by step in how to cut and keep a clean bed edge.
2. Galvanized steel: the best value steel landscape edging
The STIRLINGEAR galvanized steel kit is the cheapest way to put real metal at a bed line: ten powder-coated black panels, each 40 inches long and 5 inches high, covering 33 feet with 11 hammer-in stakes, for $69.99. That is about $2.12 a foot.
Read the geometry before you buy, because the listing is unusually honest about it and most buyers miss it. Of those 5 inches, roughly 3 go underground and 2 show above the turf. You are getting a clean low-profile line and a shallow barrier, not a deep one. For an ordinary bluegrass or fescue lawn that is on the edge of enough, and for the money it is the best line-per-dollar on this page. Where it loses: three inches in the ground is not enough against bermudagrass or quackgrass, cut ends and scratches will eventually bloom rust through the galvanizing, and stony soil will fight the stakes. Wear gloves, the edges are sharp by design.
3. Cor-Ten steel at six inches: the best metal landscape edging overall
The Edge Right hammer-in kit is the one product here that states the number the rest of the page says matters: 6 inch depth, in 16-gauge Cor-Ten steel, 48 inch strips, five to a pack for 20 feet at $130. That is $6.50 a foot, three times the galvanized kit, and it buys twice the buried depth in heavier stock. Edge Right's own listing says the weathering steel can last well over 100 years and that the edging shrugs off a string trimmer.
Cor-Ten is weathering steel: it rusts deliberately and the rust layer becomes the finish rather than the failure, going warm orange-brown then darkening. That patina forms over roughly six to nine months, and the runoff stains what it touches while it does, so keep it away from pale patio stone and light gravel through the first season. If you want the same look for less and can live without a stated depth, the budget Cor-Ten six-pack gives you 20 feet of 40 by 6 inch strips with six stakes for $63.99, about $3.20 a foot.
4. Aluminum: best for wet ground and coastal yards
The Dreamscape E-Z Edge kit is 12 slide-together strips of six feet each, 72 feet total, at $298, which works out to $4.14 a foot and makes it the most expensive metal by volume here. What you buy is the one thing steel cannot offer: the aluminum strips will not rust, ever. In salt air or in a bed that sits wet, that is worth the premium.
Two caveats. The 36 anchoring spikes in the kit are steel, so the anchors will corrode long before the edging does. And the listing does not state a buried depth, so treat the depth as unknown rather than assume it matches the six inch strips above. In an average dry suburban bed, galvanized steel does the visible job for half the money.
5. No-dig plastic coil: the cheapest landscape edging that works
The Tegarbed no-dig coil is 40 feet of 2 inch flexible plastic border with 50 spiral spikes for $19.99, or $0.50 a foot, and it is the cheapest thing on this page that is not free. No trench: you lay the coil on the line and drive the spiral spikes through it into the soil.
Be clear-eyed about what two inches buys. This is a mulch dam and a visual line, not a serious root barrier, and 50 spikes for 40 feet tells you how much anchoring thin plastic needs. For a rented yard, a first bed, or a border you expect to redraw next year, it is the right amount of money to spend.
6. Pound-in poly: best for mowing straight over the border
The EasyFlex pound-in edging gives you a 20 foot coil and 6 anchoring stakes for $20.94, around $1.05 a foot, in a 4.5 inch straight-top profile made from recycled plastic. The straight top is the point. Set level with the turf it becomes a mowing strip, so the outside mower wheel rides on the border and you stop string-trimming that bed entirely, and the listing rates it to withstand string trimmers besides.
Pound-in means you score the soil and drive it down with a rubber mallet rather than opening a trench first, which is far less work than it sounds on soft ground and considerably more on hard clay. Soak the line the day before if your soil is heavy, or read our notes on working with clay soil first.
7. Composite: best depth without metal in the garden
The EasyFlex composite kit is a 40 foot coil with 24 anchoring stakes for $57.59, roughly $1.44 a foot, and the maker calls it contractor grade. The 4 inch wall is mostly buried: the listing says it installs at least 3 inches in the ground, so what you see is about an inch of dark line over a barrier at the depth that matters. That makes it quietly one of the better buys here, since it puts as much underground as the galvanized steel kit for two thirds of the price, and it cannot rust or rot.
8. Recycled rubber: best for rocky ground
The TISHO rubber border ships six 3 inch by 48 inch sections, 24 feet in total, for $89.95, which is $3.75 a foot and made entirely from recycled tires. Rubber earns its place in one specific yard: the stony one. Steel stakes stop dead on buried rock and thin plastic snaps, while rubber sections sit on the surface and take spikes wherever the soil actually accepts them, so a rocky border becomes possible instead of infuriating. The cost is looks, since rubber stays visibly rubber, and recycled rubber generally lightens with UV exposure.
9. Edging stones: the look most people picture, with a catch
Scalloped and interlocking edging stones are the best selling border material in the country, and they are the reason a lot of people are reading this page. Real concrete scallops are sold by the piece at any local yard for roughly $2 to $5 a foot, and they are honestly the weakest performer of anything here on the one spec that counts: they sit on the surface, bury almost nothing, and each piece is a straight segment, so a curve becomes a row of gaps that grass walks through in a season.
They are still the right pick when the look is the point and the bed line is straight. If you want the appearance without hauling concrete, the Suncast interlocking border is stone-look poly rather than stone, at $35.48 a kit, and the sections slide together and tap in with a mallet with no digging at all. Call it what it is: a decorative border that ships, not a root barrier.
10. Wood log roll: best short decorative accent
A WORTH log roll is 47 inches long and 6.5 inches high for $29.99. Run the arithmetic and it is $7.66 a foot, the most expensive material on this page, so treat it as what it is: an accent for a four foot stretch by a gate or around a single specimen, not a way to edge a 60 foot border. If the roll is untreated, wood in soil contact is also on a clock, and that is the deal you are making for the cottage-garden look.
11. Brick edging: the best formal flower bed edging you can mow along
Brick set in a shallow trench over compacted base is the classic formal edge, and it is the one material here that is close to permanent while still being a do-it-yourself job. Budget about $3 to $6 a foot for the brick itself from a local yard, because shipping masonry is what makes it expensive online, then add base gravel, sand, and restraint spikes on top of that.
Get the orientation right, because this is where most guides are wrong. A soldier course, brick stood on end with the narrow face out, is under four inches wide, which is narrower than a mower wheel. For a border you can actually run the mower along, lay the brick flat instead, giving you roughly eight inches of hard surface. Either way the work is in the base, not the brick: dig, compact, screed sand, set, and check level constantly, because a brick course telegraphs every mistake down the whole run. If you are lifting turf to open that trench, our guide to removing sod cleanly saves you the worst of it.
12. Natural stone: best rustic border
Fieldstone, flagstone offcuts, or cobbles set into a trench give you a border with no seams to align and no manufactured repetition, which is exactly why informal and cottage gardens use it. Expect $8 to $25 a foot depending on the stone, sold by the ton at a local yard. The trade is that stone is set, not driven, so the gaps between pieces are grass highways unless you set them tight and back them with something. It is also the heaviest option by a wide margin, and the one most likely to end with a wheelbarrow and a sore back.
13. Poured concrete curbing: best zero-maintenance permanent border
A contractor extrudes a continuous concrete curb along your bed line in a single pass, in any curve, usually with a decorative top. It is the only option here that is truly maintenance free, and it will outlive everything else on the page. Figure $8 to $18 a foot installed, at the higher end for a stamped or colored finish. Two things to understand before you sign: it is permanent in the sense that changing your mind means demolition, and continuous concrete needs control joints or it will crack where the ground moves. This is the right answer for a finished landscape you intend to keep, and the wrong one for a garden still finding its shape.
How much does landscape edging cost?
These are what you actually pay for a 60 foot bed border, not the per-foot figure times sixty, because every kit ships in a fixed length and you round up to the next one.
| Choice | 60 ft of border | What you also spend |
|---|---|---|
| Spade-cut trench | $0 | Two hours a year, one spade you already own |
| No-dig plastic coil | About $40 for two 40 ft kits | An afternoon, and replacement in a few seasons |
| Pound-in poly | About $63 for three 20 ft kits | An afternoon, no trimming afterward |
| Composite | About $115 for two 40 ft kits | An afternoon |
| Concrete edging stones | About $120 to $300 | A day, and grass in the joints |
| Galvanized steel | About $140 for two 33 ft kits | An afternoon, then nothing for years |
| Budget Cor-Ten steel | About $192 for three 20 ft kits | An afternoon, plus rust runoff while it weathers |
| Brick, laid yourself | About $180 to $360 in brick | A full weekend of base work, plus gravel and sand |
| Aluminum | About $298 for one 72 ft kit | An afternoon |
| Cor-Ten steel at 6 in | About $390 for three 5-packs | An afternoon, then nothing for decades |
| Natural stone | About $480 to $1,500 | A weekend, a wheelbarrow, and a sore back |
| Poured concrete | About $480 to $1,080 | Nothing, and no changing your mind |
Which landscape edging actually stops grass?
None of them stop it permanently, and any product page that says otherwise is selling you something. What buried depth changes is the frequency. Rank this page by that one spec and the picture is honest.
- Buries nothing. Edging stones, rubber, and anything that taps in on the surface. These are borders and mulch dams. Grass crosses them.
- Two inches. No-dig plastic coil. You will notice creep inside one season.
- Three inches. The galvanized steel kit and the composite coil. Below the four inch threshold extension sources give, but close, and enough for an ordinary cool-season lawn that gets recut occasionally.
- Four and a half inches or more. Pound-in poly, and a full six inches on the Edge Right Cor-Ten. This is a real barrier, and it is the band where you stop thinking about the bed line for years.
Nothing on this page holds back bermudagrass or quackgrass without you patrolling the line, because both send rhizomes deeper than any of it. If the grass is already in the bed, get it out first with the technique in our weeding tools guide, then edge behind it.
How to choose garden edging for your bed
Most garden edging ideas fail on one of these seven questions, so answer yours first.
- You want it to look like a garden, not a product. Cut a trench edge, and buy a spade rather than edging.
- You want to install it once and genuinely forget it. Cor-Ten at six inches, or aluminum if the ground stays wet.
- You want a crisp line for the least money that still buries. Galvanized steel, or the composite coil for less.
- You want to stop string-trimming that bed. Pound-in poly with a flat top, or brick laid flat.
- You are spending as little as possible. No-dig plastic coil at about $0.50 a foot.
- Your soil is full of rock. Recycled rubber, since it does not have to be driven.
- The bed shape is still changing. A trench edge or plastic coil, and nothing you would resent tearing out.
Frequently asked questions
What is the cheapest way to edge a garden bed?
Cutting a trench edge with a spade is free and looks better than anything you can buy, at the cost of a recut once or twice a year. If you want a physical border, no-dig plastic coil is the cheapest option that works, at about $0.50 a foot, or roughly $40 for a 60 foot bed once you round up to two kits. Skip landscape fabric as an edging substitute, since it stops nothing at the bed line.
How deep does landscape edging need to go to stop grass?
Four inches is the working threshold. University of Illinois Extension notes that an edge four inches deep and wide can easily contain bluegrass, and most hammer-in kits fall short of it: a typical galvanized strip buries about three inches. Anything that only taps into the surface, including edging stones and rubber borders, is a visual line rather than a barrier. Six inches is the point where you stop thinking about the bed line for years.
Is metal or plastic landscape edging better?
Metal, for almost everyone. Steel is thinner, stiffer, and lasts many times longer, and the cheapest steel costs about four times what plastic coil does rather than ten. Plastic wins in three cases: a very tight budget, a border you expect to move, and ground so rocky that stakes will not drive. Composite is the honest middle, since it buries as deep as budget steel for less money. Aluminum is the version of metal to buy if rust is a concern.
What is the best edging for a flower bed?
For a flower bed specifically, the answer is usually a cut trench edge or a buried steel strip, because both let you push mulch right up to the line without it washing onto the lawn. Skip anything that sits on the surface, since mulch escapes over the top of a two inch border every time it rains hard. If the bed line curves, that rules out brick, stone, and scalloped edging stones, none of which bend.
What is the best landscape edging for curves?
Steel and plastic coil, because both bend freely without cutting or faceting. A spade-cut trench edge follows any curve exactly and is the best of all on a serpentine bed line. Avoid brick, stone, and log rolls on tight curves: they do not bend, so the curve becomes short straight segments with gaps at every joint, and grass finds those gaps within a season.
Can you mow over landscape edging?
Only if the top is flat and set level with the turf. A straight-top pound-in border, or a flush course of brick laid flat at about eight inches wide, is designed for the mower wheel to ride on, which is what eliminates string-trimming along that bed. A brick soldier course stood on end is under four inches wide, narrower than a mower wheel, so it does not qualify. Rolled tops, scalloped stone, and log rolls all sit proud of the grass and have to be trimmed by hand.
The bottom line
If you want one decision to last, buy the six inch Cor-Ten and pay the $6.50 a foot, because depth is the only spec that changes how often you fight the bed line. If the budget is the constraint, galvanized steel at about $140 for a 60 foot border is the best line-per-dollar here, as long as you know you are burying three inches and not six. And before you buy anything, go and look at a bed with a well cut trench edge, because it is free, it is the best looking border in this guide, and the tool that cuts it is one you need for the rest of the garden anyway.
Next: how to cut and keep a clean bed edge for the technique, the best lawn edgers if you would rather cut the line with a machine, and how to build a raised garden bed if the answer turns out to be walls instead of edging.
