1. Prepare the Site for Your Brick Planter:

  • Choose the desired location for your planter.
  • Clear the area of any vegetation and roughly level the ground.
  • To minimize the need for brick cutting:
  • Approximate the dimensions of the planter.
  • Place the bricks in position and measure more precisely.

Note: It’s possible and helpful to cut bricks if your space is relatively small.

2. Build the Formwork:

  • Put on your protective gloves.
  • Cut two formwork boards to match the exterior dimensions of the planter using a handsaw.
  • Nail the boards together to create a frame.
  • Place the frame directly on the ground and check for levelness using a spirit level.

3. Pour the Concrete Slab:

  • Prepare an adequate amount of mortar by mixing cement, sand, and water in a ratio of 1:4:1/2 using a trowel.
  • Pour the mortar into the formwork, stopping about 3 cm from the top edge of the boards.
  • Smooth the surface using a trowel.
  • Do not let the mortar fully harden; move on to the next step.
  • Prepare the jointing mortar as instructed on the packaging.
  • Apply a 1 cm layer of jointing mortar against the formwork boards.

4. Lay the First Row of Bricks:


  • Place the bricks of the first row, aligning them against the formwork and tapping them to improve adhesion.
  • Regularly check their levelness using a spirit level.
  • After completing the row, leave a vertical drainage joint every three bricks to allow water to escape.

5. Build the Subsequent Rows:

  • Apply another 1 cm layer of jointing mortar on the first row.
  • Continue with the following rows, following the same procedure and offsetting the bricks with each new row.
  • Fill all the vertical joints.
  • Regularly check the vertical alignment using a spirit level and adjust the position of the bricks by tapping them.

6. Finishing Touches:

  • Smooth the joints using a jointing iron.
  • Remove any excess mortar before it fully dries.
  • Remove the formwork.
  • Use a damp sponge to clean the planter’s surface.

7. Fill Your Brick Planter:

  • Once your planter is complete, it’s time to fill it with vibrant plants. Before doing so, follow these steps:
  • Place a layer of gravel or rocks at least 10 centimetres deep at the bottom for adequate drainage.
  • Cut a piece of geotextile fabric to fit the dimensions of your planter and place it on top of the rocks.
  • Fill the planter with potting soil or compost suitable for the plants you intend to grow.
