To make raised garden beds with brick, set out a stable brick wall on a solid base, line the interior for drainage, then fill it with rich soil before planting.
If you want a vegetable or flower plot that looks tidy and lasts for years, learning how to make raised garden beds with brick is a solid project. Brick walls hold soil in place, frame paths, and give your garden structure that still looks good when plants die back in winter.
Before you lift the first shovel, you need a clear plan for bed size, wall height, footing, drainage, and soil mix. Getting these details right from the start means fewer cracks in the wall, less back-breaking maintenance, and happier plants.
Planning A Brick Raised Garden Bed Layout
Good planning saves time, money, and effort later. Start with sunlight, access, and overall layout, then move on to detailed measurements.
Sun, Access, And Garden Flow
Most vegetables and many flowers grow best with six to eight hours of direct sun. Watch where shadows from trees, fences, and buildings fall during the day, and choose a spot where beds get steady light in the main growing season.
Leave clear paths at least 60 cm wide around each bed so you can bring in a wheelbarrow and reach plants without stepping on the soil. Building several smaller beds instead of one long one makes crop rotation and access easier, as raised bed guides from university extension services often point out.
Bed Size And Height For Brick Walls
For height, 30–45 cm (12–18 in) of soil suits most crops. Deeper beds up to 60 cm (24 in) help where native soil is poor or you want less bending when you garden. Taller walls need a stronger footing and may need a thicker wall or short piers to resist soil pressure.

The table below gives a quick overview of sizes and materials that work well for raised beds built with brick in most home gardens.
| Feature | Suggested Range | Notes For Brick Beds |
|---|---|---|
| Bed Width | 75–120 cm (2.5–4 ft) | Narrower if accessed from one side only |
| Bed Length | 2–4 m (6.5–13 ft) | Shorter beds reduce wall bowing |
| Wall Height | 30–60 cm (12–24 in) | Higher walls need strong footing |

| Soil Depth | 30–45 cm (12–18 in) | Enough for most vegetables and herbs |
Tools And Materials For A Brick Raised Bed
Gathering everything before you start keeps the build smooth and steady. You do not need specialist masonry gear for a modest bed, but sturdy basics help a lot.
Core Tools
- Spade and garden fork for digging and levelling
- Wheelbarrow for soil, gravel, and bricks
- Builder’s string line, stakes, and a tape measure
- Set square for corners and a long spirit level
- Rubber mallet, brick trowel, and jointing tool
- Buckets or a mixing tray for mortar
- Gloves, knee pads, and safety glasses
Materials Checklist
Choose durable materials that do not break down or leach into soil. Guidance on the safety of materials for raised beds notes that brick, stone, and many untreated woods are suitable for edible gardens when used sensibly. You can see an example of this kind of advice from the University of Maryland Extension. Safety of materials used for raised beds
- Solid, frost-resistant clay bricks
- Sharp sand and cement for mortar (if using mortared walls)
- Compacted gravel or crushed stone for the footing
- Landscape fabric, cardboard, or thick newspaper for weed control
- Topsoil, compost, and coarse material such as sharp sand or leaf mould
- Optional capping bricks or stone for
How To Make Raised Garden Beds With Brick Step By Step
This project breaks down into clear stages: set out the shape, prepare the footing, build the wall, then line and fill the bed. Move slowly on the first course of bricks; speed later depends on that base.
Step 1: Mark Out The Bed
Start by measuring the bed footprint on the ground. Knock in stakes at the corners, then run string between them. Measure both diagonals; matching measurements show that the rectangle is square. Adjust the lines until you are happy with the alignment in relation to paths, fences, and views from the house.
Step 2: Prepare The Ground And Footing
Cut away turf and obvious roots along the line of the wall. Dig a trench around the perimeter that is roughly twice the width of a brick and 15–20 cm deep. This trench becomes the footing for the wall.
Fill the trench with compacted gravel or crushed stone, tamping it down in layers until it is firm and level. A flat, solid base spreads the weight of the wall and helps water move away from the bricks, which reduces frost damage in cold climates.
Step 3: Lay The First Course Of Bricks
Mix mortar to a thick, workable consistency. Spread a bed of mortar on the gravel footing, then press the first brick into place. Tap it gently with the mallet and check levels along and across the wall. Lay the next brick with a small mortar joint, keeping the top surface flush with the first.
Keep checking with the string line and the spirit level as you move around the bed. Any tilt or bump in this course will echo through every course above it, so this stage deserves patience.
Step 4: Build Up The Wall
Once the first course is straight and level, add the next course with staggered joints. This pattern strengthens the wall and gives it a cleaner look. Scrape away squeezed-out mortar as you go so you can finish the joints neatly later.
For a bed around 30–40 cm tall, three to four half-brick courses usually work well. For something higher, consider short piers or a thicker wall spaced along the length to resist soil pressure. If you garden in a wet area, leave small gaps or pipes low in the wall at intervals to act as drain outlets.
Step 5: Line The Interior And Add Drainage
When the mortar has set, brush off loose bits and tidy the joints. Line the inner face of the wall with landscape fabric if you want to keep fine soil from washing through gaps. Fix the fabric just below the top of the wall so it stays hidden once he base is heavy clay or hard surface, spread 8–10 cm of coarse material such as gravel, broken brick, or small stone across the bottom. This layer creates space for excess water to collect and move away from roots, a point also stressed in guides such as the raised bed advice from the Royal Horticultural Society.
Step 6: Fill With A Raised Bed Soil Mix
Now fill the bed with a loose, fertile mix. Many raised bed resources suggest something close to forty percent screened topsoil, forty percent mature compost, and twenty percent coarse material like sharp sand or fine bark. Blend these in shallow layers so the bed settles evenly.
Water the soil as you fill to help it settle and to reveal any low spots. Top up until the soil sits a few centimetres below the brick edge so mulch and water stay inside the bed during heavy rain.
Step 7: Plant And Mulch
Once the soil is in place, you can plant. Group crops by height and spacing: low salad plants near the front, taller fruiting crops and trellises toward the back. This keeps sunlight reaching everything and makes the bed easier to tend.
Finish with a layer of organic mulch such as shredded bark, straw, or compost. Mulch helps keep moisture in, limits weed growth, and gives the brick edge a tidy frame of dark soil and plant growth.
Building Raised Garden Beds With Brick Edging In Different Spaces
The same basic method adapts well to different garden shapes and sizes. You can build single feature beds, neat rows, or a full kitchen garden grid.
Compact Courtyard Or Patio Beds
In small yards or on patios, short brick beds around 2 m long and 75 cm wide work well. A height of about 30 cm gives enough soil for salads, herbs, and compact flowers while still feeling light in a tight space.
On solid surfaces, make sure water has a route away from the bed. Leave tiny gaps near the base of the brickwork or build drain pipes into the wall so water can flow to a gravel strip or channel rather than pooling inside the soil.
Kitchen Garden Rows In Larger Yards
Where space allows, a set of parallel brick beds gives a classic kitchen garden look. Keep each bed shorter than 4 m to limit strain on the walls and to make filling, weeding, and harvesting less tiring.
Paths between beds should be wide enough for a barrow and a person side by side. Many gardeners aim for at least 60–75 cm. Using the same brick and height for each bed ties the whole area together while varied planting brings colour and life through the year.
Soil Depth And Crop Ideas For Brick Raised Beds
Choosing crops that match your bed depth keeps plants vigorous and reduces wasted effort. The table below pairs common soil depths with suitable plants.
Suitable Crops Notes 30 cm (12 in) Lettuce, spinach, radish, many herbs Shallow roots; steady moisture helps 40 cm (16 in) Beans, peas, beetroot, spring onions Good for mixed salad and veg beds 45–50 cm (18–20 in) Tomatoes, peppers, cabbage, broccoli Extra depth supports taller crops 50–60 cm (20–24 in) Carrots, parsnips, deep-rooted flowers Helps in shallow or stony native soil 60 cm+ (24 in+) Berry bushes, dwarf fruit trees Use strong walls and footing Ongoing Care For Brick Raised Garden Beds
Once the hard work of construction is done, care is simple. Most of the effort goes into keeping the soil rich and the brickwork sound.
Feeding And Refreshing The Soil
Each year, spread a few centimetres of compost over the soil surface and fork it gently into the top layer. This keeps nutrients and soil life topped up without turning the whole bed, which can disturb structure and worms.
Keep an eye on soil level. As organic matter breaks down, the surface will sink a little. Adding compost and a small amount of topsoil from time to time keeps bed depth where you need it for roots and moisture storage.
Looking After The Brickwork
After heavy rain and frosty periods, walk around the bed and check for loose bricks or cracked mortar. Repoint joints where needed before gaps grow wider. Clear any debris from drain gaps at the base of the wall so water still has a clear route out.
With steady care, a brick raised bed becomes a long-term feature of your garden. Once you understand how to make raised garden beds with brick and match soil depth to the crops you love, you gain a neat, dependable growing space that rewards that effort for many seasons.
