Step 1: Plan Your Wall

The first step is to plan the layout of your wall. Consider the height, length, and curves of the wall. You will also need to decide where the wall will be located and how it will connect to the surrounding landscape.

Step 2: Dig the Trench

Once you have planned the layout of your wall, you will need to dig a trench. The trench should be at least 12 inches deep and 18 inches wide. The trench should also be level and free of debris.

Step 3: Install the Base

The next step is to install the base of the wall. The base should be made of gravel and sand. The gravel should be placed in the bottom of the trench and compacted. The sand should then be placed on top of the gravel and compacted.

Step 4: Lay the Rocks

Now it's time to lay the rocks. Start by laying the largest rocks at the bottom of the wall. These rocks should be placed in a staggered pattern to create a stable base. Once the first course of rocks is in place, you can continue laying the rocks in a similar pattern.

Step 5: Backfill the Wall

Once the rocks are in place, you will need to backfill the wall. The backfill should be made of soil, sand, or gravel. The backfill should be placed in the space between the rocks and compacted.

Step 6: Install the Cap

The final step is to install the cap. The cap is a layer of rocks that is placed on top of the wall. The cap helps to protect the wall from the elements and adds a finishing touch.
