Required Tools

  • Drill with Phillips screwdriver tip
  • Rubber mallet, or hammer and piece of wood for cushioning


Step 1. Choose and prepare the site. Locate a level area on the ground that will receive the appropriate amount of sunlight needed by your plants. Keep in mind that vegetables require lots of sun. To learn more about siting your bed, read the article on Location and Set-Up in the Kitchen Garden Planner. Prepare the ground for planting. If you are installing the Raised Bed on a lawn, remove the sod and loosen the soil with a shovel or spade so that the plant roots will be able to penetrate to a depth of 6".

Raised Bed Corners

Push the cedar board into the Raised Bed Corner until it is fully seated.

Step 2: Assemble the sides and corners. Place the Cedar Boards on their sides to form a square or rectangular bed and seat the ends into the four Raised Bed Corners. Make sure the Boards are fully seated and level with the bottom of all four corners. For 3' x 12' and 4' x 12' Cedar Raised Bed models, assemble the long sides of the bed by inserting the 6' Boards into the In-Line Connectors.

Step 3: Connect the boards to the Raised Bed Corners and In-Line Connectors using the Phillips screws provided. Make sure the boards are fully seated and secure by making adjustments as you work your way around the bed. To make it easier, drill starter holes in the wood using the screw holes in the corners and connectors to guide you. Finish by tightening the screws with a Phillips screwdriver.

Step 4: Insert the black plastic Corner Caps into the top of each Raised Bed Corner and In-Line Connector. Tap into place with rubber mallet or hammer, using a piece of wood for cushioning.

Step 5: Fill the Raised Bed to the top edge with a mixture of garden soil and plenty of organic matter, such as compost. You may mix in other materials such as peat, perlite, vermiculite or coir (coconut fibers) to help aerate and retain moisture in the soil. To figure out how much soil and amendments you need, use the Soil Calculator.
