Paving stone garden edging not only has a practical use in the garden, it also adds a decorative touch. It will help keep weeds and other unwanted vegetation from growing into your flowerbeds as well as framing the bed. Paving stone garden edging is a bit more expensive than plastic edging but will last for years without the cost of replacement. The stone comes in a variety of colors and sizes, so gardeners have many options when selecting an edging stone.
Measure the area in your landscape where you will be installing the stone edging. Measure from the top edge of where the stone edging will start to where you will be laying the last piece. This will help you figure out how many pieces of edging are required to complete the job.
Calculate how many stone edging pieces are required. For example, if the area measures 30 feet in length and your paving stones are 10 inches in length, you will need 30 pieces of edging to complete the job. Always purchase at least one extra edging piece in the event you come up short when installing it.
Clear the area of any grass, weeds or other vegetation growth, as well as sticks, rocks or other material that will keep the stones from laying evenly in the soil. Spray the area with herbicides and wait for the vegetation to die or dig it up with a shovel. Clear an area that is 2 to 3 inches wider than the width of the edging stones. Rake the area level after removing the unwanted debris and vegetation.
Dig a trench that is one-third as deep as the width of your paving stone edging. You want to place just enough of the edging piece into the soil to hold it in place, but have at least half of it sticking up from the soil. The soil will eventually cover the edging pieces if they are installed too deep.
Place a piece of edging horizontally into the trench and then lay another piece next to it, being sure the pieces are lying in the soil at the same depth and are level. Pack soil under the edging pieces or remove some, if the pieces are sitting too high or too low in the trench.
Pack the soil around the first piece of edging and around half of the second edging piece, allowing enough room to lay the next piece in front of it. Continue laying the edging pieces next to each other, being sure they are level until you have all of the pieces in place.
Water the area where you laid the edging in well to firm the soil up around the stone edging pieces and hold them in place. Sweep away any dirt to give the area a clean and finished look.
