DIY Brick Garden Edging: A Complete Guide to Beautifying Your Outdoor Space

Introduction to Brick Garden Edging

Brick garden edging is one of the most timeless and rewarding landscaping projects a homeowner can undertake. Whether you are looking to define the boundary between your lawn and flower beds, create a clean separation along a pathway, or simply add a touch of classic elegance to your outdoor space, brick edging delivers results that are both practical and visually stunning. The natural texture and warm tones of brick complement virtually every garden style, from formal English gardens to relaxed cottage landscapes.

What makes brick edging particularly appealing is its remarkable durability. Unlike plastic or metal edging materials that can warp, fade, or degrade over time, properly installed brick edging can last for decades with minimal maintenance. Bricks are resistant to weathering, frost, and the general wear and tear of outdoor life. This longevity means that the time and effort you invest in a DIY brick edging project will continue paying dividends for many years into the future, making it one of the best value-for-money improvements you can make to your garden.

Beyond durability, brick edging offers a satisfying hands-on project that does not require specialist skills or expensive professional help. With the right preparation, a few basic tools, and a weekend of work, most homeowners can achieve professional-looking results. The sense of accomplishment that comes from stepping back and admiring a neatly edged garden bed you built yourself is genuinely hard to beat. This guide will walk you through every stage of the process, from planning and materials through to finishing touches and ongoing care.

Planning Your Brick Garden Edging Project

Before you purchase a single brick or pick up a shovel, careful planning is essential to ensure your project runs smoothly and delivers the results you are hoping for. Start by walking around your garden and identifying exactly where you want the edging to go. Use a garden hose or length of rope to lay out the proposed line of the edging, allowing you to visualize curves and straight sections before committing. Take photographs from different angles so you can review your plans and make adjustments before any digging begins.

Measuring accurately is the next critical step. Walk along the proposed edging line and measure the total length in metres or feet, adding approximately ten percent to account for cutting waste, breakage, and any mistakes during installation. For standard brick edging laid flat, you will need roughly four to five bricks per linear foot. For soldier-style edging where bricks are set vertically on end, the number increases to around seven or eight per linear foot. Having a clear calculation ready before you visit the supplier will prevent costly return trips and project delays.

Consider also the style and pattern of your edging at this planning stage. Flat bricks laid horizontally give a wide, low-profile border that suits relaxed garden styles. Soldier edging, where bricks stand upright in a neat row, creates a more formal and defined look. Diagonal or herringbone patterns add visual interest but require more precise cutting. Sketching your preferred style on paper alongside a simple site diagram will help you communicate your vision to suppliers and keep you focused throughout the installation process.

Tools and Materials You Will Need

Gathering all your tools and materials before you start is one of the most important habits of a successful DIY gardener. Running back and forth to the hardware store mid-project wastes time and breaks your momentum. For brick garden edging, the good news is that most of the tools required are common items you may already own or can rent inexpensively. Having everything laid out and ready at the start of your working day makes the project feel manageable and keeps the workflow moving steadily forward.

Here is a comprehensive list of the tools you will need for a standard brick edging installation:

• Spade or flat-edged garden spade for cutting a clean trench edge
• Trowel for shaping the trench bottom and applying mortar
• Rubber mallet for setting bricks firmly without cracking them
• Spirit level to ensure your edging remains even and consistent
• String line and stakes for keeping straight sections perfectly aligned
• Tape measure for accurate spacing and depth checks
• Safety goggles and gloves for protection when cutting bricks
• Angle grinder or brick splitter if cutting is required for curves or ends
• Bucket and mixing paddle or a small concrete mixer for mortar
• Stiff brush for cleaning excess mortar from brick faces

For materials, you will need reclaimed or new clay bricks, sharp sand, cement, and optionally a proprietary landscaping adhesive for a mortar-free installation. Reclaimed bricks are a popular choice because their weathered appearance blends naturally into garden settings almost immediately, whereas new bricks can take a season or two to develop that lived-in character. When selecting bricks, look for engineering bricks or hard-fired clay bricks that are rated for outdoor use and frost resistance, as softer facing bricks may crumble after repeated freeze-thaw cycles.

Step-by-Step Installation Guide

Begin the installation by marking out your edging line precisely using string and stakes for straight sections, or spray paint for curved areas. Once your line is clearly marked, use your flat-edged spade to cut a clean, vertical trench along this line. The trench should be deep enough to accommodate the height of your bricks plus a two-inch bed of compacted sand or mortar beneath them. For flat-laid bricks, a trench of around four to five inches deep is typically sufficient. For upright soldier edging, you will need a trench of eight to ten inches to bury roughly one-third of the brick below ground for stability.

Once your trench is dug, compact the base firmly using the end of a piece of timber or a hand tamper. Add a two-inch layer of sharp sand to the base of the trench and level it carefully with a trowel, checking with your spirit level as you go. This sand bed provides drainage beneath the bricks, which is crucial for preventing frost heave in colder climates. If you prefer a more permanent installation, mix a stiff mortar of three parts sharp sand to one part cement and use this as your bed instead of loose sand, pressing each brick firmly into the mix.

Lay your bricks one at a time, pressing each firmly into the sand or mortar bed and tapping gently with your rubber mallet to set them level. Use your string line as a constant reference for alignment, and check frequently with your spirit level both along the row and across individual bricks. Leave a consistent gap of around half an inch between bricks if you plan to fill the joints with mortar or jointing sand. Once a section is complete, step back regularly to check that the edging looks straight and even from a distance, as small deviations are much easier to correct before the mortar sets.

For curved sections of edging, you may need to cut some bricks at an angle to maintain tight, neat joints around the curve. Mark the cut line clearly on each brick with a pencil and use an angle grinder fitted with a diamond blade, or a dedicated brick splitter, to make the cut. Always wear safety goggles and gloves when cutting bricks, and work in a well-ventilated area to avoid inhaling dust. Take your time with curves, as this is where the quality of a finished edging project is most clearly visible and where rushed work is most likely to show.

Finishing Touches and Jointing

Once all your bricks are set in position and the mortar bed has had time to cure for at least twenty-four hours, it is time to address the joints between the bricks. For a traditional, formal look, mix a fairly stiff mortar and press it carefully into each joint using a pointing trowel. Work in small sections to prevent the mortar from drying before you can shape it, and use a jointing iron or the rounded handle of a tool to press the mortar into a slightly concave profile. This recessed profile sheds rainwater efficiently and gives a clean, professional finish to the completed edging.

For a more informal or low-maintenance approach, brush dry kiln-dried jointing sand into the gaps between bricks, sweeping it diagonally across the surface so it fills each joint completely. Compact the sand with your fingers or a piece of timber, then brush away any excess from the brick faces. Apply a fine mist of water from a garden hose to help the sand settle and consolidate. This method allows slight flexibility in the edging, which can actually be beneficial in areas subject to ground movement or frost, as the individual bricks can shift slightly without cracking.

After jointing, clean any mortar smears or sand residue from the faces of the bricks using a stiff brush and clean water. Work quickly if removing fresh mortar, as it becomes significantly harder to remove once it has fully cured. For older or set mortar spots, a diluted solution of muriatic acid can be carefully applied with a brush, but this requires protective gloves and eyewear and must be thoroughly rinsed off with water immediately after use. Once your edging is clean and dry, take a moment to tidy the surrounding soil and replant any disturbed ground cover or edging plants that were moved during the project.

Maintenance and Long-Term Care

One of the greatest advantages of brick garden edging over other border materials is how little ongoing maintenance it requires once properly installed. A well-laid brick edge will largely take care of itself through the seasons, requiring only occasional attention to keep it looking its best. The most common maintenance task is checking for and correcting any bricks that have shifted due to frost heave, tree root activity, or soil settlement. An annual check in early spring, after the last frost has passed, is all that is needed to catch and address any movement before it becomes a more significant problem.

To correct a shifted or sunken brick, simply lever it out carefully using a flat screwdriver or garden trowel, add or remove sand or mortar from the base as needed, reset the brick, and check it for level. If mortar joints have cracked or eroded over time, repoint them using fresh mortar mixed to the same consistency as the original. Keeping joints well-filled prevents weeds from gaining a foothold in the gaps, which is one of the most persistent maintenance challenges for any type of garden edging. Applying a proprietary patio or brick sealant every few years can also help to protect against staining and reduce weed germination in the joints.

Weeds are the gardener’s perennial challenge, and brick edging is not entirely immune. Inspect the joints regularly during the growing season and remove any weed seedlings promptly before they establish a deep root system that can disrupt the brickwork. A sharp-bladed hand tool or dedicated weeding knife makes this task quick and satisfying. Applying a residual weed suppressor to the joints after cleaning them out can provide several months of protection during peak growing periods. With consistent, light-touch maintenance through the year, your brick garden edging will remain sharp, stable, and attractive for many seasons without ever demanding a major overhaul.

Design Inspiration and Creative Variations

Once you have mastered the fundamentals of brick edging installation, a world of creative possibilities opens up. One of the most popular design variations is the angled or diagonal layout, where bricks are set at a forty-five degree angle to the edging line, their corners pointing upward to create a distinctive sawtooth profile. This style, sometimes called sailor edging or diamond edging, adds considerable visual interest and is particularly effective when used to border formal rose beds or herb gardens. The repeating geometric pattern catches the light beautifully and gives even a modest garden a structured, designed quality.

Mixing brick colours and textures is another effective way to add personality to your garden edging. Combining weathered red clay bricks with buff or grey engineering bricks in alternating patterns creates a striking two-tone effect. You can also introduce other materials alongside brick, such as sections of natural stone, salvaged roof tiles set on edge, or cobblestones, to create an eclectic, characterful border that reflects a genuinely individual style. The key is to maintain a consistent height and level throughout so that the edging reads as a unified element even when the materials vary.

Raised brick edging offers yet another creative avenue worth exploring. By building the edging two or three courses of brick high rather than a single course, you create a raised bed effect that gives your planting areas greater depth and visual presence. Raised edging is particularly practical on sloping ground, where it helps retain soil and prevent erosion. It also makes garden beds more accessible for those with limited mobility, as the raised sides double as a low seat for comfortable weeding and planting. For a raised edging, it is advisable to use mortar throughout to ensure structural stability and to lay the second and third courses in a staggered bond pattern for added strength.

Lighting is a final finishing touch that can transform your brick garden edging from a daytime feature into a year-round garden highlight. Small solar-powered LED lights set into the jointing between bricks, or low-voltage landscape spotlights positioned to graze along the edging line at an angle, create dramatic shadow effects after dark that emphasize the texture and pattern of the brickwork. This kind of garden lighting is relatively inexpensive, straightforward to install, and makes a remarkable difference to the atmosphere of an outdoor space in the evening hours. Combined with well-chosen planting alongside the edging, thoughtful lighting completes the transformation of a functional border into a genuine garden feature.
