Landscape blocks decorate garden and lawn areas. Blocks are sold in various sizes, colors and types. They can be used to create borders and even retaining walls. Installing concrete landscape block often requires cutting the blocks to fit the desired area. With the use of specific tools, you can score the surfaces of blocks and split them apart. Saws may also be used to cut completely through concrete landscape blocks.
