Tips for How to Lay Concrete Stone Edging for a Flower Bed

Place stakes along the outermost edges of your flowerbed every few feet. Run string to connect the stakes and define the border of the bed.

Dig a trench, working along the string border outward. The trench should be at least as wide as your largest stone and 3 inches deeper than the average thickness of your stones.

Mix your concrete with water in an old wheelbarrow following the directions on the package for your brand of concrete for the approximate amount of water needed. Mix the concrete until it is smooth and isn’t runny or overly lumpy.

Fill a 3-foot length of the trench with concrete mix and smooth the mix relatively flat. Set your stones into the concrete, working in a pattern or set randomly, as desired, until that stretch of edging is complete. Push the stones downward to set them into the concrete and lower the upper surface of the stones level with the soil line.

Continue adding concrete in 3-foot sections at a time from one end of the trench to the other and placing stones until the entire edging is laid. Push any stones down that stick up or may be hit with a mower blade. Leave the concrete to set up for one to two days.
