Planning and Preparation
Before you start building your raised bed retaining wall, take some time to plan and prepare. This will save you headaches and ensure your project turns out well.
First, check the size of your raised bed and its location to avoid disturbing any surrounding garden or utility areas. Verify that your wall won't be obstructing any existing paths or walkways.
Also, don't forget to verify local building codes for permits needed for taller walls. This will save you from potential fines or having to tear down your wall and start over.

Choose Your Materials

When planning your garden's retaining wall, it's essential to choose a durable material that can withstand the elements. Wood is a budget-friendly option that can work well, especially if you're looking to save some money.
A smooth surface is crucial to prevent chemical leaching, so ensure the material you choose is suitable for raised beds.
Supplies
To start your project, you'll need to gather the necessary supplies. You can find the Planter Wall Blocks at Home Depot or Lowe's, and they come in a pack of twelve.
You'll also need two 2 x 8 pressure treated redwood planks, which can be any type of wood you prefer. You can use whatever wood you like, as long as it's 2 x 8 in size.
Here's a list of the tools you'll need to have on hand:
- Circular saw for cutting the wood
- 1/2' rebar 4' long for added support
- Level to ensure everything is straight
- Hammer for tapping things into place
Building and Construction
To build a raised bed retaining wall, start by leveling the first row of materials with the ground. This ensures that the blocks or wood are even and can be stacked on top of each other.
You'll want to use landscape block adhesive between the courses to add stability to the final wall. This adhesive looks like caulk but is meant to bind the blocks together.
To level each row, make sure to place the blocks at measured distances and keep stacking until the wall reaches the desired height. You can also use a 3 pound sledge to score the brick and cut it if needed, especially if you have a gap that's too small for a brick to fill.

Provides Efficient Drainage
Using retaining wall blocks for your construction project can provide efficient drainage. The soil can drain quickly and aerate the roots of plants.
Retaining wall blocks are designed to allow water to pass through and prevent it from accumulating behind the wall. This is especially beneficial in areas with high rainfall or where the soil tends to be waterlogged.
The consistent drainage provided by retaining wall blocks helps prevent soil erosion and reduces the risk of water damage to your property.

Start Building Your
To start building your retaining wall, begin by leveling the first row of materials with the ground, ensuring the blocks or wood are even and placed at measured distances.
You'll want to use some landscape block adhesive between the courses to add stability to the final wall. This adhesive is like caulk, but specifically designed to bind the blocks together.
Leveling the first row is crucial because it will automatically level the second row, making it easier to lay the bricks on top.
If you have a tile saw, cutting bricks will be a breeze, but if not, you can use a hammer and chisel. A 3-pound sledge is a good tool to have for this task, as it gets the job done efficiently.
To ensure a solid foundation, extend the base trench into the slope far enough to bury one block for each step up that is needed. Then, fill the trench with base rock and compact it to create a stable base course.

Step 4: Insert Rebar
Insert rebar into the center hole of the blocks on each corner to prevent the blocks and wood from being pushed apart by the soil pressure.
Make sure the top end of the rebar is below the top side of the 3rd block. This ensures the rebar is securely anchored in the ground.
Drive the rebar down far enough so that it is firmly stuck into the ground. This provides stability and support to the bed.
