How to Create a Raised Flower Bed Using Stone

Measure out the dimensions of the raised bed using a tape measure. Oklahoma University suggests making your bed 3 feet wide by 25 feet long for easy fertilizer calculations. This size also permits easy access to the center of the bed from both sides. Mark the bed out using stakes and string.

Remove the turf from the area using a spade. Till the area to a depth of 4 inches to work the soil properly.

Lift your largest stones to the side of the excavated area. Using the largest stones at the bottom of the wall and decreasing the size as you build the wall creates stability.

Pour mortar powder into a bucket. Slowly mix in the recommended amount of water into the mortar, stirring with a trowel until the mortar is the consistency of frosting.

Apply mortar in between the joints of the first layer of the flower bed wall with a trowel. Apply the mortar toward the back of the rocks to hide the mortar. This gives your wall a dry stacked look.

Set the second course of rocks on top of the base layer, setting the second course back one third of the rocks' width. Staggering the rocks gives the wall better stability. Offset the rocks like brickwork to create even greater stability.

Apply mortar to the second layer as well, hiding the mortar toward the back of the joint. Repeat with every subsequent layer.

Fill the excavated area with soil.
