Project Overview

Assembling a raised garden bed is a simple project you can do, and you won’t even need tools. We’ll show you how to build the garden bed, with handy tips about the best way to put it together. Once you’ve finished, the garden bed will not only make a great feature for your home but will let you grow your favourite flowers, plants and herbs.

Step by Step Instructions

1 Put on your safety gear
2 Assemble the end piece of the garden bed
3 Assemble one side of the garden bed
4 Assemble the second side of the garden bed
5 Assemble the second end piece
6 Put on the protective edging
  • Step 1. Put on your safety gear

    Before you start assembling the raised garden bed, make sure you put on your safety gloves. Some of the metal edges of the bed could be sharp. Putting the garden bed together will be easier if you have someone to help you. One person can hold the corrugated sheets of metal in place, while the other one inserts the bolts into the pre-drilled holes and tightens the nuts.

  • Step 2. Assemble the end piece of the garden bed

    Take one of the garden bed end pieces and line it up with the pre-drilled holes in one of the curved corner pieces. Put a washer on a bolt through the top pre-drilled hole and tighten the wing-nut so that it’s finger tight. This makes easier to undo the nuts and bolts if you make a mistake. Repeat this process for the bottom pre-drilled hole. Make sure the wing-nuts go on the inside of the garden bed. 
  • Step 3. Assemble one side of the garden bed

    Next line up one of the long pieces of the garden bed with the pre-drilled holes in the corner piece. Put a washer on a bolt and insert it in the top hole and hand tighten the wing-nut. Repeat this in the pre-drilled hole at the bottom. To complete one side, take a second long piece and repeat the above process and attach it to the first long piece.

  • Step 4. Assemble the second side of the garden bed

    Take another corner section and attach it the other side of the end piece. Repeat Step 3 to assemble the second side of the garden bed. Only secure the top and bottom pre-drilled holes using the bolts, washers and wing-nuts. Make sure that the wing-nuts are on the inside of the garden bed and only finger tighten them.

  • Step 5. Assemble the second end piece

    Assemble the second end piece by repeating Step 2. Continue assembling the long pieces with the corner sections and the ends of the garden bed until you have built the L shaped raised garden bed. Once you have built the garden bed, insert the rest of the nuts and bolts in the pre-drilled holes and use the spanner, provided in the kit to tighten all of them securely.

  • Step 6. Put on the protective edging

    To make the corrugated iron edge safe, put the protective edge all around the top of the garden bed. Then move the garden bed to where you’d like it in your garden. Now you are ready to fill it with a mixture of soil and compost and start growing your favourite plants, flower and herbs.
