How to build an 8-foot diameter concrete brick flower bed
Bricks Ready for Recyling into a Flower Bed (

Creating a raised flower bed makes a striking landmark in your yard, especially when you circle it with bricks. Setting the ground level a little higher than the ground immediately draws attention to the flowers in the bed. You don't want to get any wider than a 4-foot reach from any side since you won't be able to reach in easily. In this case, we are constructing an 8-foot round, three-layered brick flower bed that is a little more tricky than a square one, but still quite within the capabilities of most homeowners.

Skill level:

Things you need

  • 105 bricks
  • Eight 80-pound bags Quikrete
  • Four 50-pound bags sand
  • Wheel barrow
  • Hoe
  • Trowel
  • 4 by 4 square board
  • String
  • Stake
  • Spraypaint

  1. 1

    Find the centre of the flowerbed you wish to construct. Pound a stake about 6 inches into the ground. Tie a 5-foot string to the stake. At the other end of the string, tie the can of spray paint. You want the string to be 4-feet long between the stake and the can of paint, so adjust accordingly.

  2. 2

    Stretch the string out and start spraying as you walk around the stake. Only spray halfway and stop. Go back to your original starting spot and go in the other direction as you spray until you meet the previous spot where you stopped. You should now have a 4-foot radius marked around the stake. Remove the stake and string.

  3. 3

    Dig a trench that is 4 inches deep and 6 inches wide (or basically the width of the hoe) right over the painted line. This will be the footer for your raised flower bed wall. Brick tends to deteriorate if it is left on the ground, but if you can place it on a concrete foundation, it will last much longer.

  4. 4

    Mix up an 80-pound bag of Quikrete with a half a bag of sand in a wheelbarrow. Add water a gallon at a time, stirring it in with a hoe. Once the whole batch has no more dry patches and is a good sludgy texture, shovel it into the prepared trench. Level it off with a short piece of board so that it is level with the ground. Continue to mix and add the concrete until the trench is filled. Allow it to set for about four hours.

  5. 5

    Get your square board within reach of the trench and pour a wheelbarrow load of concrete onto it in a pile. Working quickly, trowel some concrete onto the new trench. Take a brick and dab both ends with one-quarter inch of concrete and lay it on top of the concrete, centred on the footing. Square it in place using a level. Do the same thing with the next brick and so on until you have a whole circle of bricks in place.

  6. 6

    Build two more levels of bricks, checking as you go for a level side and a level top. Alternate the bricks so they are stacked with one centred over two. Clean up any splats of concrete that fall or ooze out between the bricks. Allow the mortar to dry overnight before shovelling in some rich soil just over the top of the brickwork. It will settle later.

  7. 7

    Plant your flowers with the tallest ones in the centre and medium-size ones around it. This kind of bed is especially attractive when some of the flowers drape over the sides.
