How to make a raised garden bed


  • Two 2”x12” wooden planks, measuring eight feet long
  • Two 2”x12” wooden planks, measuring four feet long
  • 12 pieces of rebar, measuring two feet long
  • A rubber mallet
  • Newspaper or cardboard
  • Soil to fill the finished frame.

Step one

Begin by positioning your boards on a level section of ground, laying the boards down with their inner corners touching.

Stand one long board on its side and using a rubber mallet to hammer two pieces of rebar one foot from each corner, a few inches deep into the ground.

Step two

You can prop up the short sides using a piece of rebar at the centre of each for temporary support.

Prop up the second long side and adjust the alignment of your frame as necessary.

Then hammer the rebar a few inches deep one foot from each corner of the second long side.

Step three

Add more support to the structure by hammering rebar a few inches deep a foot from each corner on the short sides and remove the temporary supports.

Add two pieces of rebar two feet apart along each long side.

These will then reinforce the frame when it is filled with soil and then hammer the rebar until six to 10 inches are exposed above ground.

Step four

The next step is to line the bottom of the bed with newspaper or cardboard and wet it thoroughly.

To conclude, you should fill your bed with soil to within a few inches of the top and then you can begin planting items in your raised bed.

Alternative materials you can use

If you do not wish to make the raised bed out of wooden planks, you can use the following materials:

  • Wattle: Use wattle by weaving a frame with long, flexible sticks.
  • Logs: If you have logs, you can create the frame by choosing straight pieces which are at least one foot in diameter.
  • Concrete blocks: Concrete blocks are also an effective material and can be used by placing these blocks with open ends up to provide extra growing room.
  • High and mighty: A wait-high bed can also be constructed for those with physical limitations.
  • Stone can be used but skilled labour may be required for construction and footings.
  • Brick is a strong and durable material to use.
