Why Edging Grass with Bricks is a Gardener’s Best Friend
There is a reason why professional landscapers and historical estates rely on clay and concrete pavers for their boundaries. Unlike plastic or thin metal strips, a heavy masonry border stays put and handles the elements without warping or cracking.
The primary benefit is the creation of a mowing strip, which is a flat surface where you can run your lawnmower’s wheels. This eliminates the need for string trimming or hand-shearing every time you mow the lawn, saving you hours of labor over a single season.
Beyond the practical side, bricks offer a timeless aesthetic that complements almost any home style, from rustic cottages to modern builds. They provide a sense of structure and “intentionality” to your garden beds that softer edges simply cannot match.
Furthermore, a deep-set brick border acts as a physical root barrier, making it much harder for aggressive grass species like Bermuda or St. Augustine to invade your prized perennials. It is a one-time investment that pays dividends in reduced weeding and a cleaner-looking yard.
Choosing the Right Materials for Your Border
Before you start digging, you need to decide which type of masonry best fits your garden’s personality. Not all bricks are created equal, and choosing the right material ensures your border survives the freeze-thaw cycles of winter.
Red Clay Bricks are the traditional choice, offering a warm, weathered look that gains character over time. If you choose these, ensure they are “severe weather” rated so they do not flake or crumble when exposed to moisture and frost.
Concrete Pavers are a fantastic alternative if you want more variety in color and texture. They are incredibly durable and often come in interlocking shapes that can make installation on curves a bit easier for beginners.
Reclaimed Bricks can add a sense of history and charm to your landscape, especially if they have old foundry marks. Just be sure to inspect them for structural integrity, as older bricks can sometimes be more porous and prone to breakage.
You will also need a base material, such as leveling sand or crushed stone. This is the foundation of your project; without a solid base, your bricks will eventually sink or shift, ruining that perfectly straight line you worked so hard to create.
The Importance of Landscape Fabric
While some gardeners skip this step, I highly recommend laying a narrow strip of heavy-duty landscape fabric at the bottom of your trench. This prevents the base sand from migrating into the soil below and helps suppress any stubborn weeds from pushing up through the joints.
Calculating Your Needs
To determine how many bricks you need, measure the total length of your planned border in inches. Divide that number by the length of your chosen brick to get a rough estimate, but always buy 10% more than you think you need to account for cuts and breakage.
Essential Tools You Will Need Before You Dig
Having the right tools on hand makes the process of edging grass with bricks much smoother and prevents unnecessary trips to the hardware store. Most of these are basic garden staples, but a few specialized items will ensure a professional finish.
A half-moon edger is your best friend for creating clean, vertical cuts in the sod. While a standard shovel can work, the flat blade of an edger allows for much more precision when you are following a string line or a garden hose curve.
You will also need a rubber mallet for setting the bricks into the sand. Never use a metal hammer, as it will likely crack the masonry; the rubber mallet provides enough force to seat the brick without causing damage.
A spirit level is non-negotiable if you want your border to look professional. I prefer using a 2-foot level for straight runs and a smaller torpedo level for checking individual bricks as I go along.
- Garden Hose or String Line: For marking out the shape of your border.
- Hand Trowel: For fine-tuning the depth of your trench.
- Tamper: For compacting the soil and base material.
- Safety Gear: Sturdy gloves and knee pads will make the job much more comfortable.
A Step-by-Step Guide to Edging Grass with Bricks
Now that you have your materials and tools ready, it is time to get your hands dirty. Follow these steps carefully, and you will have a border that remains stable and beautiful for many years.
Step 1: Mark Your Path
Start by laying out your garden hose to define any curves, or use a string line for straight edges. Take your time with this step, as it is much easier to adjust a hose than it is to move a trench once it is dug.
Once you are happy with the shape, use a can of landscaping spray paint to mark the line directly onto the grass. This gives you a clear guide to follow with your edger and ensures your border doesn’t “drift” as you work.
Step 2: Cut the Sod and Excavate
Use your half-moon edger to cut straight down along your painted line. Once the perimeter is cut, use a spade to remove the grass and soil, creating a trench that is about two inches wider than your bricks.
The depth of the trench should equal the thickness of your brick plus about one to two inches for the base material. If you want the bricks to sit flush with the lawn for easy mowing, make sure the trench is deep enough to accommodate that.
Step 3: Prepare the Base
Clear out any large rocks or roots from the bottom of the trench and use a hand tamper to firm up the soil. Lay down your landscape fabric, then add an inch of leveling sand or fine crushed stone.
Smooth the sand with a small board or your trowel until it is relatively level. This layer of sand is crucial because it allows you to “wiggle” the bricks into place and adjust their height individually.
Step 4: Set the Bricks
Place your first brick at the start of the trench and tap it firmly with your rubber mallet. Use your spirit level to check that it is level both lengthwise and across its width.
Place the second brick tightly against the first one and repeat the process. If a brick sits too low, add a little more sand underneath; if it is too high, tap it a bit harder or remove a small amount of sand.
Step 5: Backfill and Finish
Once all the bricks are in place, fill the small gaps on either side of the border with the soil you excavated earlier. Pack the soil down firmly with your feet or a tool to lock the bricks in place.
Finally, sweep some polymeric sand or plain fine sand into the joints between the bricks. This helps prevent weeds from growing in the cracks and provides extra stability to the entire structure.
Creative Patterns and Layout Ideas
The way you orient your bricks can completely change the “vibe” of your garden. There is no right or wrong way to do it, but some patterns are more functional than others depending on your specific needs.
The Soldier Course involves standing the bricks up on their ends, side-by-side. This creates a taller barrier that is excellent for keeping mulch from washing away during heavy rains, though it doesn’t provide as wide a mowing strip.
The Sailor Course lays the bricks flat on their widest side, perpendicular to the lawn. This is the gold standard for mowing strips, as it provides a wide, stable path for your mower wheels and a very clean visual line.
If you have a very formal garden, a Running Bond pattern—where the bricks are laid end-to-end—looks sleek and understated. This is also the easiest pattern to install if you are working with tight curves or circular flower beds.
For a more rustic or “cottage” feel, try a Cobbled Look using irregularly shaped bricks or stones. This requires a bit more patience during the leveling phase, but the finished product feels organic and timeless.
Troubleshooting Common Installation Pitfalls
Even with the best intentions, DIY projects can hit a few snags. Knowing how to handle these common issues will keep your project on track and ensure a long-lasting result.
One common problem is heaving, where the bricks push upward during the winter. This is almost always caused by poor drainage or a base that is too shallow; ensure your trench has a solid layer of sand to allow for minor soil movement.
If you find your bricks are sinking over time, it usually means the soil underneath wasn’t compacted enough before the sand was added. Use a heavy tamper or even a 4×4 post to really pack down the earth at the bottom of your trench.
Weeds growing between the bricks can be a nuisance, but they are easily managed. Using polymeric sand in the joints is the best preventative measure, as it hardens into a mortar-like consistency that blocks weed seeds from reaching the soil.
If you encounter a large tree root while digging, do not simply chop through it, as this could harm the tree’s health. Instead, try to bridge over the root by adding a bit more sand or slightly shifting the path of your border.
Frequently Asked Questions About Edging Grass with Bricks
How deep should the trench be for a brick border?
Generally, you want a trench that is about 4 to 6 inches deep. This allows for 1 to 2 inches of base material (sand or gravel) plus the thickness of the brick itself. If you want a flush-mount mowing strip, the top of the brick should be level with the soil line of your lawn.
Do I need to use mortar for my brick edging?
For most residential garden beds, a “dry-laid” method using sand is preferred. It allows for natural drainage and makes it much easier to repair or move the border in the future. Mortar is only necessary if you are building a formal, raised masonry wall.
Can I use old bricks I found in my yard?
Yes, but be cautious. Some older bricks are “interior grade” and will absorb water, causing them to shatter during a freeze. Test a few by soaking them in water and leaving them out; if they stay solid, they are likely safe for edging grass with bricks in your landscape.
How do I keep the bricks from moving over time?
The key to stability is a well-compacted base and tight joints. Filling the gaps with sand and packing soil firmly against the back of the bricks (on the garden side) creates a “lock” that prevents shifting. For extra security, you can use hidden plastic edging on the backside to hold them in place.
Will a brick border damage my lawnmower blades?
If installed correctly (flush with or slightly below the grass height), your mower blades will pass right over the bricks without contact. This is why edging grass with bricks is so popular—it allows you to get a close cut without the risk of hitting stones or metal edges.
Conclusion: Transform Your Landscape Today
Building a brick border is one of the most satisfying “quick wins” you can achieve in your garden. It provides instant gratification by cleaning up messy lines and offers long-term benefits by reducing your weekly maintenance chores.
