How to Build a Stone Path
Consider your home's architecture when choosing a style of stepping stone. If there is keystone, brick or faux rock on your exterior walls, bring the same texture and color into the stepping stones. The path shown here was selected to coordinate with the coral hues of the patio pavers. Matching the color or texture of a nearby landscape element will give your path a professional look.
Note: Choose a surface with enough texture that it won't be slippery when wet, especially if the path will be near a pool. And avoid very dark stepping stones, which can become too hot for bare feet in the summertime.
Step 1: Clear and Fill
Determine the boundaries of your path and remove all vegetation from the area. If you use an herbicide, apply it at least twice with three days in between. Once the vegetation is gone, put down 2 inches of leveling sand. Drag a 2x4 across the surface of the sand to make it very level.
Step 2: Lay the Stones
Set the stepping stones into the sand about 6 to 8 inches apart. Keep the surface of the stones well above the sand, and make sure each new stone is level with the one before it.
Step 3: Level the Stones
As you settle the stones into place, use a level to check each surface. When the level is parallel to the house, the bubble should be right in the middle, indicating that the stone is on an even grade. When the level is perpendicular to your house, you want to see a slight positive slope. This will allow water to slide off the stones and away from your house. This is particularly important when stepping stones are placed close to an exterior wall.
Step 4: Install a Weed Barrier
A weed barrier will ensure that your stone path stays tidy and virtually maintenance-free for years. Once all the stones are in place and appropriately leveled, lay the weed barrier on top. Use garden shears to carefully cut holes for each stone. Weigh the barrier down with some pebbles as you work.
Step 5: Fill with Pebbles
For a clean look, surround the stepping stones with small pebbles in a complementary, yet contrasting color. The pebbles should be deep enough to cover the weed barrier completely, but their surface should remain slightly lower than the surface of the stones.
Step 6: Install Edging
To keep the pebbles from slipping into the surrounding landscape, you'll need to install edging. For a clean, minimalist look, a narrow strip of black metal works well. For a country cottage ambience, use brick-shaped pavers that coordinate with your stepping stones. Dig a trench that allows you to place the edging material deep enough so it won't be a tripping hazard. The top of the edging should be just an inch above the pebbles.
