Expect to pay $20 to $100 per cubic yard of landscaping stone, or $0.75 to $4 per cubic foot, depending on the material you pick. Landscape rocks are an attractive and cost-effective option for a broad range of projects, including stone and gravel roads, patios and walks, and retaining walls. A yard of stone measuring 20 feet by 10 feet (6 m by 3 m) will use up 1 cubic yard (Cub. ft.) and will cost about $100. The price of a yard of stone depends on the type of rock you select and its size. The more expensive the stone, the finer its grain and the deeper the color. Coarse-grained stones are cheaper but take longer to wear away in the landscape. Varying levels of hardness can be found in a single rock type; for example, granite is harder than sandstone but less hardy than limestone. Harder materials require more care in placement since they're more likely to damage tools or the vehicle transporting them. The cost of a yard of stone also varies depending on where you buy it. Since most yards don't sell the whole cubic yard at once, we often ask what percentage of the whole thing they'll sell you. For example, if they say half a yard, that's five cubes, or 2.5 cu. Ft., which is enough stone for two 4-foot by 8-foot (1.2 m by 2.4 m) paths.
