Brick Edging for Landscaping Design Ideas | Borders That Last

Brick edging creates a durable, defined border between lawn and garden beds using clay or concrete bricks, keeping grass at bay while adding timeless visual structure.

A crisp line between grass and a flower bed is one of those details that separates a finished yard from a work in progress. Brick edging delivers that line without looking temporary or cheap. It handles freeze-thaw cycles, shrugs off lawn mower passes, and ages better than plastic or metal alternatives. Whether you’re after a straight formal border or a curving garden path, the same basic technique works — and it’s a weekend project for a capable DIYer.

Why Choose Brick Edging Over Plastic or Metal?

Brick edging wins on longevity and looks. A thick plastic strip might last a few seasons before cracking; cheap metal edging bends under a stray tire. Clay bricks, properly installed on a gravel base, stay put for decades. The warm red tones of a traditional clay edger like the Pacific Clay Jumbo complement both mulched beds and green lawns without competing with the plants. Concrete bricks offer a grayer, more modern option — either way, the material weight keeps it grounded where lighter alternatives wander.

What Brick Edging Costs and How Much You Need

A pallet of Pacific Clay Jumbo Clay Red Edgers runs around $357 and holds 60–70 bricks. Each brick measures 11.5 inches long, 3.5 inches wide, and 3 inches tall. To estimate your total, run a rope along the bed edge, measure the length in feet, multiply by 12, and divide by 11.5 (the brick length). Add 10 percent for cuts and curves. For a straight 50-foot border, you need roughly 57 bricks plus six spares — call it a full pallet and you’ll have leftovers for repairs.

Step-by-Step: Installing Brick Edging the Right Way

The method below comes from the hands-on guide published by This Old House, and it works in any US climate when you respect the base depth.

Step 1: Measure and Mark

Lay a garden hose or rope along the edge you want to create. Step back and adjust it until the curve looks right — fixing it now is free, fixing it after the trench is dug costs a lot of sweat. Mark the line with spray paint or flour.

Step 2: Dig the Trench

Dig a trench 4 to 6 inches deep and several inches wider than the brick length — about 14 inches across for a standard 11.5-inch brick. A flat spade or a half-moon edger works well for straight sections; a narrow trenching shovel helps with curves.

Step 3: Compact the Base Material

Spread 2A modified limestone (a 2-inch stone chip with dust) in the trench, about 2 inches per layer. Tamp each layer firmly with a hand tamper until it’s solid. The goal is a packed base 2 to 3 inches deep total — skipping the compaction is the single most common reason brick edging sinks after winter.

Step 4: Mix and Spread the Setting Bed

Combine stone dust and Portland cement in a 6-to-1 ratio — six shovelfuls of dust to one shovelful of cement. Mix them dry in a wheelbarrow, then spread a 1-inch layer over the compacted limestone. A trowel smooths it out evenly.

Step 5: Set the Bricks

Press each brick into the cement mixture, one at a time. Tap it with a rubber mallet until the top sits flush with the surrounding ground — or about half an inch lower than the grass height if your lawn is thick. Check alignment frequently with a straightedge and a mason’s line. For curves, cut a few bricks into wedge shapes or buy pre-made keystones to keep the gaps consistent.

Step 6: Backfill and Sweep

Backfill the back edge of the trench with leftover stone dust, then top it with soil. Spread polymeric sand over the bricks, sweep it into the joints, and whack each brick lightly with the mallet to settle the sand deep. Sweep away the excess, then mist the line gently with a hose — just enough to dampen and activate the sand without washing it out of the gaps.

Design Ideas: Straight Lines, Curves, and Sawtooth Patterns

Straight brick borders suit formal gardens and walkways. Curved beds look softer and more natural — the same installation method handles both, though curves demand more cutting and patience. A sawtooth pattern (bricks set on their edges at alternating angles) adds visual texture for flower beds and path edges. If you want the bricks to double as a subtle seating edge or a mowing strip, make sure they sit flush with the ground; raised bricks will either get hit by the mower blade or force you to reach for a string trimmer every time you cut the grass.

Common Mistakes That Ruin Brick Edging

The most frequent error is skimping on the trench depth. Digging only two inches deep guarantees the bricks will lift and shift during the first freeze-thaw cycle. The second mistake is skipping the tamper — loose base material settles unevenly, and within a year the edging looks like a wave. The third is setting the bricks too high. A brick that sits above the grass line catches the mower blade and chips or gets launched. Set them flush or a hair below. Finally, don’t leave excess polymeric sand on the brick faces before you hose it down. If that sand gets damp while sitting on the brick surface, it stains, and the stain is permanent.

Brick vs. Concrete: Which Edging Material Fits Your Yard?

Clay bricks offer that classic warm red color and a slightly rougher texture that ages gracefully. They’re fired at high temperatures, so they resist moisture absorption better than concrete. Concrete pavers cost less per unit and come in gray, charcoal, and tan tones that suit modern landscapes. The trade-off: concrete is more porous and can flake after repeated freeze-thaw cycles unless it’s a high-density paver. For most US climates, a proper gravel base under either material solves the durability question — the base matters more than the brick type.

Finishing Checklist: What You Need and What to Watch For

Before you start, gather these tools: a rubber mallet, hand tamper, flat spade or half-moon edger, mason’s line with stakes, a framing square, a trowel, a wheelbarrow, a stiff broom, and a garden hose with a spray nozzle. The job takes one person a full day for 50 to 75 feet of border — longer runs go faster with a helper on the tamper. Work when the ground is soft but not soaked, and never on frozen soil. In regions with hard winters, the gravel base is not optional; it’s the difference between edging that stays straight and edging that turns into a pile of loose bricks every spring.
