Begin by measuring the area you intend to cover with decorative stone, then determine the type of rock you’d like to use.
Tip: Large amounts of rock to be used in driveways or walkways are generally sold by the cubic foot or half foot. Smaller bags for mulch or indoor use are sold in bags ranging from 5 to 50 pounds.
There may be some question as to how deep decorative stone should be layered. The suggested depth of coverage can vary according to the size of the individual stones.
If the stone size is 1/2 inch or less, the suggested depth is 2 inches, while stones that are 3/4 inch to 1 inch should have a depth of about 3 inches. Stones that are 1 inch or larger should have a depth of 4 inches.
A cubic yard of decorative stone (27 cubic feet) will actually cover more or less area depending on depth. Take this factor into consideration when measuring for and purchasing decorative stone.
- 160 sq. ft. at 2-inch depth
- 108 sq. ft at 3-inch depth
- 80 sq. ft. at 4-inch depth
- 54 sq. ft. at 6-inch depth
- Smaller stones may shift more in heavy rain.
- Rocks used as mulch tend to retain heat, which can reflect back onto the plants, causing them to dry out.
Choose from brick chips, crushed gravel, lava rock, river rock and marble to create pathways, mulch for garden beds, driveways and more.
The region you live in may determine the kinds of stone available for purchase in your area. Decorative stone is quarried, and stone types vary greatly by location. The cost of shipping makes anything other than local stone an extremely expensive proposition.

Painting rocks is another recent trend in landscape decor that you can use decorative stones to enjoy. Apply acrylic or glow paint to smooth river stones and place them in your gravel beds or as accent pieces around your garden stones. Small rocks can even be painted to add a flash of color to planters.
