Brick lawn edging ideas include laying bricks flat, laying them horizontally and building a short wall. Brick is an attractive choice because it is durable, easy to find and inexpensive.
Brick edging laid flat or horizontally is usually placed in a shallow trench on a bed of sand. The key is placing the brick blocks closely enough together that they do not allow plant growth or soil through.
Another similar option is to create diagonal brick edging in which the bricks are placed in the ground at a 45-degree angle against one another. Homeowners should fill in the space underneath each brick and really pack it down to keep the bricks in place.
Short walls are built along garden edges using bricks and mortar. This is a project that takes more time, but results in an attractive, long-lasting wall.
