Before you buy new edging, be sure to measure the area/areas you are working in to ensure you have enough edging for your yard.
For the simplest type of border, choose spade-cut edging. This involves using an edging tool called a spade to dig a narrow trench around the outside of the bed you are setting apart. It is the least expensive type of edging available.
Strip edging consists of a shallow barrier that is anchored beneath the ground. The very top of the edging is visible to slightly set the bed and lawn apart. Strip edging works best for creating curves and comes in plastic and metal varieties. Plastic is less expensive and easier to install. Metal edging comes in steel or aluminum and lasts longer but is less flexible.
Masonry edging, composed of stone, brick, or concrete, is the most expensive type of landscape edging. Stone is very attractive and allows you to match borders to any existing stonework you have used in the landscaping, garden, or exterior of your home. Cement borders often come in preformed sections of different shapes and styles, allowing for easier installation.
Wood edging comes in precut sections of alternating heights, either as round logs or flat boards. All types of wood edging are durable and most are affordable. The types of wood most often used include cedar, cypress, and redwood, which naturally resist rot. Pressure-treated wood is resistant to moisture and a good value for larger projects.
