Why Choose a Brick Lawn Edge for Your Garden?
When it comes to garden borders, you have plenty of options like plastic, wood, or metal. However, few materials offer the same blend of durability and charm as natural clay or concrete bricks.
A brick border acts as a “mower strip,” allowing you to run the wheels of your lawn mower directly over the bricks. This eliminates the need for string trimming and prevents those annoying grass “stragglers” from leaning over your flowers.
Unlike plastic edging that cracks in the sun or wood that rots in the damp soil, a well-installed brick border can easily last for thirty years or more. It is a one-time investment of effort that pays off every time you look at your landscape.
Beyond the practical benefits, bricks offer a sense of permanence and history. Whether your home is a modern build or a cozy cottage, the earthy tones of brick complement almost any architectural style beautifully.
Selecting the Best Bricks for Your Project
Not all bricks are created equal, and choosing the wrong type can lead to crumbling borders after just a few winters. You want to look for “paver grade” bricks rather than standard “face bricks” used for houses.
Face bricks often have holes (cores) in the center to save weight and help them bond with mortar. In a garden setting, these holes trap water, which then freezes and shatters the brick from the inside out.
Solid clay pavers are fired at much higher temperatures, making them nearly non-porous and incredibly strong. They can withstand the weight of heavy garden equipment and the constant moisture of the soil without losing their integrity.
If you want a more eco-friendly or rustic look, consider reclaimed bricks from old building sites. Just ensure they are solid and test a few by tapping them together; a high-pitched “clink” means they are structurally sound.
Concrete pavers are another excellent alternative, often available in a wider variety of colors and textures. They are uniform in size, which makes the installation process much faster for beginners who want perfectly straight lines.
Essential Tools for the Job
Before you start digging, gathering the right tools will save you multiple trips to the hardware store. You don’t need heavy machinery, but a few specific hand tools are essential for a professional finish.
- A sharp-edged spade or a specialized half-moon edger for clean cuts.
- A garden hose or long rope to map out organic, flowing curves.
- A rubber mallet to set the bricks without cracking the surface.
- A long carpenter’s level (at least 2 feet) to ensure a flat mowing surface.
- String line and wooden stakes for keeping straight sections perfectly aligned.
- A tamper or a heavy piece of 4×4 timber to compact the base soil.
In addition to tools, you will need “consumable” materials like crushed stone (often called paver base) and sharp sand. These materials create a stable foundation that prevents the bricks from sinking over time.
I also recommend a pair of heavy-duty gardening gloves. Handling dozens of bricks can be surprisingly tough on your hands, and the rough edges can cause small abrasions before you even realize it.
Step-by-Step Guide to a Professional brick lawn edge
Now that you have your materials, it is time to get your hands dirty. Following a systematic approach ensures that your border won’t shift or heave when the ground settles.
Step 1: Marking the Perimeter
Start by laying out your garden hose along the desired edge of your flower bed. If you prefer straight lines, use your stakes and string line to create a guide that is parallel to your house or fence.
Take a step back and look at the lines from different angles, including from inside your house. It is much easier to adjust a hose now than it is to move a trench later on.
Step 2: Excavating the Trench
Using your spade, cut vertically into the turf along your guide line. You want to dig a trench that is about two inches wider than your brick and deep enough to accommodate the base material.
Calculate your depth by adding the height of the brick to two inches of base material. If you want the bricks to be flush with the grass, the trench should be deep enough that only the top half-inch of the brick is visible initially.
Step 3: Creating a Solid Foundation
Fill the bottom of your trench with about an inch of crushed stone or paver base. Use your tamper to pack this down until it is rock-solid; this is the most important step for preventing future sinking.
Add a one-inch layer of leveling sand on top of the crushed stone. Do not compact the sand yet; this loose layer allows you to wiggle the bricks into a perfectly level position later.
Step 4: Setting the Bricks
Place your first brick at the start of the trench and tap it firmly with your rubber mallet. Use your level to check that it is flat both across its width and along its length.
Continue laying bricks end-to-end, keeping them as tight as possible. For curves, you may have small gaps on the outer edge, which is perfectly normal and will be filled with sand later.
Once your brick lawn edge is in place, check the height relative to your lawn. The bricks should sit slightly above the soil but low enough that your mower blades won’t strike them during a low cut.
Step 5: Securing the Joints
Once all bricks are set, pour a generous amount of polymeric sand or plain sharp sand over the border. Use a broom to sweep the sand into the cracks between the bricks.
If you are using polymeric sand, lightly mist it with water to activate the binding agent. This creates a “glue” that keeps the sand in place and prevents weeds from sprouting in the gaps.
Advanced Layouts: Soldier vs. Sailor
When installing your border, you have a few choices regarding the orientation of the bricks. The two most common styles are the “Soldier” and the “Sailor” courses.
A Sailor course involves laying the bricks flat on their widest side, end-to-end. This creates a wide, stable mowing strip that is very easy for beginners to install and level.
A Soldier course means standing the bricks up on their narrow ends. This creates a much deeper barrier against invasive grass roots, though it requires a deeper trench and more bricks per foot.
For a decorative touch, some gardeners prefer the “angled” or “sawtooth” look, where bricks are buried at a 45-degree angle. While beautiful, this style is harder to mow against and may require more frequent hand-trimming.
Common Challenges and Pro Solutions
Even the most careful gardener can run into issues during installation. One common problem is “frost heave,” where the ground freezes and pushes the bricks upward out of alignment.
To prevent this, ensure your drainage is adequate. If your soil is heavy clay, consider digging your trench slightly deeper and adding an extra inch of crushed stone to allow water to move away from the base.
Another challenge is navigating thick tree roots. Never chop through a major structural root (anything thicker than your thumb) to lay a brick. Instead, slightly adjust the curve of your border or “bridge” over the root with a thinner layer of sand.
If you find that your bricks are shifting outward toward the lawn, you can install a hidden plastic edge restraint on the garden side. This L-shaped strip is spiked into the ground and keeps the bricks locked in place.
Maintenance Tips to Keep Your Borders Crisp
While brick is low-maintenance, it isn’t “no-maintenance.” Over time, dirt can accumulate on the surface, and moss might begin to grow in the shaded sections of your garden.
Once a year, give your border a quick scrub with a stiff brush and some soapy water. Avoid using a high-pressure power washer directly on the joints, as this can blast out the stabilizing sand.
If you notice a brick has sunk, don’t worry. Simply pry it up with a screwdriver, add a handful of sand to the hole, and tap the brick back into place. It is a five-minute fix that restores the integrity of the line.
Keep an eye on the grass at the very edge of the bricks. Occasionally, runners will try to jump over the top. A quick pass with a hand edger once a season will keep that boundary looking sharp and intentional.
Frequently Asked Questions About Brick Lawn Edging
How deep should a brick lawn edge be buried?
Ideally, you should bury about half to two-thirds of the brick’s height. This provides enough lateral stability to keep it from tipping while leaving enough surface area to act as a visible border and mower strip.
Can I use old house bricks for my garden edge?
You can, but be aware that they are more prone to weathering. If you live in a climate with harsh winters, “face bricks” may begin to flake or crumble within a few years. For long-term results, solid clay pavers are much better.
Do I need to use mortar for a brick border?
For most residential gardens, a “dry-laid” border using sand and crushed stone is actually superior to mortar. Dry-laid borders can flex with the ground’s natural movement, whereas mortar will crack when the soil shifts or freezes.
How do I calculate how many bricks I need?
Measure the total length of your planned border in inches. Divide that number by the width of your brick (usually about 4 inches for a sailor course). Always buy 10% more than you think you need to account for cuts and breakage.
