How to Install Cobblestone Landscape Edging?

Here is the step-by-step process of installing landscape edging with cobblestone. You should carefully follow these steps to properly install edging in your garden.

Step 1 – Measuring

The first and foremost step in the process is measuring the length, width, and height of the cobblestones so you can determine the size of the trench. If you find that there are cobblestones with varying sizes, consider measuring the larger ones.

Step 2 – Outlining

Once you have measured everything, it’s time to mark the outline for the cobblestone landscape edging using the landscaping paint or chalk line, or you can outline the area with a spare garden hose. Make sure the outline should be as wide as the largest cobblestone. Don’t forget to add another ½ inch to ensure they are easily fit.

Step 3 – Digging a Trench

Now dig a trench in the area you outlined to a depth so your cobblestones can easily be buried and some extra 2-3 inches for base material. Make sure the width of the trench is wider than the width of the cobblestones.

Step 4 – Fill in the Trench

Now fill the trench with crushed rock or gravel to a depth of 3-4 inches and pack it down using a hand tamper. Repeat it till the desired level is achieved. If the desired depth is not achieved, add more base material and pack it down.

Step 5 – Mixing and Adding the Mortar

Using one part cement and four parts masonry sand, create a thick, soupy mortar mixture. Once you are ready with the mixture, add a 1-inch layer of mortar to the trench with a trowel. When you are installing cobblestone edging for flower beds and walkways, there’s no need for a mortar mixture. But they are required when installing driveway cobblestone edging and other exterior areas.

Once you are ready with the mixture, start filling the bottom of the trench. A 1-inch layer of mortar is required to be filled on top of the base layer.

Step 6 – Lay the Cobblestone Edging

Now start placing the cobblestone in the trench. Start placing them from the corner, so if any cutting of the cobblestones is needed, it will be at the end of the trench and the least visible. However, you should always follow the manufacturer’s guidelines and directions for cutting the cobblestone. But if you feel you are not comfortable and confident enough with the cutting, consider hiring a professional. You can also incorporate different landscape edging ideas to enhance the look of your garden and other outdoor areas.

Step 7 – Tapping Down the Cobblestones

Once you are done placing the cobblestone landscape edging in the trench, tap them down using a hammer or rubber mallet. Check the level of the cobblestone with the piece next to it, and make sure the height of each stone is the same. Also, do check the gaps between the cobblestone; they should also be uniform to improve the aesthetics of your outdoor area.

Step 8 – Filling Sand on the Top

After you have placed all the cobblestones, pour polymeric sand on top of the stones. Using a broom or paintbrush, push the sand in the remaining cracks between the cobblestone landscape edging. The reason for doing this is that the polymeric sand hardens when it comes in contact with water, so it will keep the stones from shifting. However, you need to make sure that the cobblestones perfectly complement the natural stone paving you’ve installed on your outdoors.


This is the complete and step-by-step process of installing cobblestone landscape edging. Make sure to follow these steps properly and carefully to get your beautiful edging installed outdoors. You can also hire a professional if you are not confident enough to install edging in your garden.
