This is a great, fun, creative & cost efficient way to use natural resources to make the garden of your dreams!
Step 1: Find Rocks
I found mine right outside my house. Rocks are literally everywhere, so keep your eyes open!
You can make your planter as big or small as you like.
I used about 4 wheelbarrows full of rocks for mine
Step 2: Outline The Area
Your going to want to use the bigger rocks for this. Make sure they are touching each other, and that they are not wobbly.
Step 3: Mix Your Cement
You can use cement, grout, or morter mix, but I would say that a mixture of cement and morter is best. It's up to you, but cement is really hard to mix.
The consistency of your mix needs to be pourable but not drippy.
Make sure you don't make too much at a time (it can dry up quickly)
Step 4: Pour Mix
Use a smaller bucket or a large cup to do this. Make sure to put extra in the indentations and crevasses where the rocks are touching. You may want to also use a sponge to wipe away any spillage that goes on the face of the rocks (the inside doesn't matter)
Step 5: Adult Lego's/Tetris Time!
This is the best part. You add more layers by selecting rocks to place upon the previous layer. Always make sure that there is a layer of cement on the top & bottom of each rock.
Step 6: Up Up & Away
Build your structure up until it is a height that you are happy with. Make sure that there are no empty spots or areas where there needs to be some extra cement or rock.
Step 7: Even It Out.
You can use a level tool, or just eyeball it. Just make it more even along the top.
I like to use smaller, flat rocks for this part. I feel like it gives a more "finished" look
You do not need to put layer of cement on top of your final layer of rocks
