Another beautiful material to update your landscape with is natural stone. Natural stone is an organic material that can be used for walls, patios, steps, walkways, rock gardens, boulder placements, and much more. From flagstone to 2 ton boulders natural stone can enhance any area dramatically. The cost of using this material varies depending on size and type of application. Stone can sometimes be a cheaper option though for a permanent structure stone can also be on the higher end because of machine and labor costs. That being said, the maintenance and durability will always outweigh other materials. The initial cost may be higher, but in the end, this organic material can save you thousands of dollars.
