One of the most economical types of edging is plastic. This edging usually comes in rolls that can be cut to a specific length for each landscape bed. One negative aspect of plastic landscape edging is that it is lightweight and can move to the surface of the ground and become warped if it is stepped on.
Wood edging is another popular option for landscape beds. Wood edging comes in timbers, treated boards and stair-stepped round sections nailed together. Wood edging is more expensive than plastic, but is more economical than stone or concrete. One drawback with wood edging is that it can attract termites and it tends to rot over time. Another challenge with wood edging is that it can be more difficult to configure in landscape beds that have a lot of curves.
Decorative stones, bricks or concrete edging can give an elegant look to landscape beds. These types of edging options also do a good job of keeping mulch inside landscape beds and in keeping grass out. Stone, concrete and brick edging, however, tends to be more expensive than wood or plastic, and that difference can add up if you have large landscape beds.
The least expensive type of landscape edging is a natural shovel edge. Cutting a v-shaped edge along the border of a landscape bed with a shovel is a way to add a natural look to your yard. Shovel edging keeps mulch from washing away by the trench that is created with the v-cut, but it is not as effective as raised edging.
