How Much Are Landscaping Rocks is a common question for homeowners and landscape professionals alike. This comprehensive guide from rockscapes.net breaks down the costs, types, and factors influencing the price of decorative rocks, gravel, and stones, helping you make informed decisions for your landscaping project. Whether you’re looking for garden rocks, river rock, or something more specialized, understanding the pricing is the first step.
1. What Factors Influence the Cost of Landscaping Rocks?
Several factors determine how much landscaping rocks cost; understanding these can help you budget effectively and choose the right materials.
- Type of Rock: Different types of rocks have different price points.
- Gravel: Typically the most affordable option, gravel is priced lower due to its abundance and ease of production.
- River Rock: Slightly more expensive than gravel due to its smoother texture and natural appeal.
- Lava Rock: Lightweight and porous, lava rock can be more costly due to its unique properties and aesthetic.
- Crushed Stone: Depending on the type and size, crushed stone can vary in price.
- Flagstone: Used for pathways and patios, flagstone is generally more expensive due to its flat shape and use as a building material.
- Boulders: Large decorative rocks that are the most expensive due to their size, weight, and the difficulty of handling and transporting them.
- Size and Quantity: Smaller rocks are generally cheaper per piece, but you’ll need more to cover an area. Larger rocks, like boulders, are sold individually and can significantly increase costs. Bulk purchases often lead to lower prices per unit.
- Location: Prices vary depending on where you live. Areas closer to quarries or rock suppliers will typically have lower prices due to reduced transportation costs. According to research from Arizona State University’s School of Earth and Space Exploration, in July 2025, transportation costs are a major factor in material pricing.
- Supplier: Different suppliers offer varying prices based on their overhead, sourcing, and markup. Local nurseries, landscaping supply stores, and large home improvement retailers all have different pricing structures.
- Delivery Costs: Don’t forget to factor in delivery costs. These can add up, especially for large quantities or heavy rocks. Some suppliers offer free delivery within a certain radius or for orders over a specific amount.
- Installation Costs: If you’re hiring a professional landscaper to install the rocks, their labor costs will also contribute to the overall project expense.
- Seasonal Demand: Prices may fluctuate depending on the time of year. Demand for landscaping materials typically increases in the spring and summer, potentially leading to higher prices.
2. What Is the Average Cost of Landscaping Rocks Per Ton/Cubic Yard?
Knowing the average cost per ton or cubic yard helps in budgeting for your landscaping project. These prices are estimates and can vary based on the factors mentioned above.
| Type of Rock | Average Cost per Ton | Average Cost per Cubic Yard |
|---|---|---|
| Gravel | $20 – $50 | $30 – $75 |
| River Rock | $40 – $80 | $60 – $120 |
| Lava Rock | $70 – $120 | $100 – $180 |
| Crushed Stone | $30 – $60 | $45 – $90 |
| Flagstone | $150 – $300 | $225 – $450 |
| Boulders | $100 – $500+ | Varies |
- Gravel: One of the most affordable options, typically used for pathways, driveways, and as a base material.
- River Rock: Popular for decorative purposes, drainage, and creating natural-looking water features.
- Lava Rock: Lightweight and provides excellent drainage, often used in gardens and around plants.
- Crushed Stone: Used for a variety of purposes, including drainage, pathways, and as a base for patios.
- Flagstone: Flat stones used for creating patios, walkways, and stepping stones.
- Boulders: Large, decorative rocks that can be used as focal points in a landscape design.
3. How Much Does it Cost to Install Landscaping Rocks?
The cost of installing landscaping rocks depends on the size of the project, the type of rock, and whether you hire a professional.
- DIY Installation: If you choose to install the rocks yourself, you’ll save on labor costs. However, you’ll need to factor in the cost of tools (shovels, rakes, wheelbarrows) and your time. DIY installation is suitable for smaller projects and those with some landscaping experience.
- Professional Installation: Hiring a professional landscaper ensures the job is done correctly and efficiently. Labor costs can range from $50 to $150 per hour, depending on the complexity of the project and the landscaper’s experience. Professional installation is recommended for larger projects, intricate designs, or when dealing with heavy materials like boulders.
Factors Affecting Installation Costs:
- Project Size: Larger areas require more time and materials, increasing the overall cost.
- Rock Type: Heavier or more difficult-to-handle rocks (like boulders) will increase labor costs.
- Site Preparation: If the area needs to be cleared, leveled, or have existing vegetation removed, this will add to the cost.
- Design Complexity: Intricate designs or features (like rock gardens or water features) require more skilled labor and time.

5. How to Calculate the Amount of Landscaping Rocks Needed?
Calculating the correct amount of landscaping rock is crucial to avoid overspending or running short.
- Measure the Area:
- For Rectangular or Square Areas: Measure the length and width in feet and multiply them to get the area in square feet.
- For Circular Areas: Measure the diameter in feet, divide by 2 to get the radius, and use the formula: Area = πr² (where π ≈ 3.14159).
- For Irregular Areas: Break the area into smaller, more manageable shapes, calculate the area of each, and add them together.
- Determine the Desired Depth: Decide how deep you want the rock layer to be, in inches. A common depth is 2-4 inches for decorative ground cover.
- Convert Depth to Feet: Divide the depth in inches by 12 to convert it to feet (e.g., 3 inches / 12 = 0.25 feet).
- Calculate Volume in Cubic Feet: Multiply the area in square feet by the depth in feet to get the volume in cubic feet.
- Convert Volume to Cubic Yards: Divide the volume in cubic feet by 27 (since there are 27 cubic feet in a cubic yard) to get the volume in cubic yards.
- Consider Waste: Add 5-10% to your calculation to account for settling and waste.
Formula:
- Volume (cubic yards) = (Area (square feet) x Depth (feet)) / 27
Example:
Let’s say you have a rectangular garden bed that is 10 feet long and 5 feet wide, and you want a 3-inch layer of river rock.
- Area: 10 feet x 5 feet = 50 square feet
- Depth: 3 inches / 12 = 0.25 feet
- Volume: (50 square feet x 0.25 feet) / 27 = 0.46 cubic yards
- Add Waste (5%): 0.46 x 0.05 = 0.023 cubic yards
- Total: 0.46 + 0.023 = 0.483 cubic yards
You would need approximately 0.483 cubic yards of river rock for this project.
6. How to Save Money on Landscaping Rocks?
Landscaping can be expensive, but there are ways to reduce the cost of your rock project.
- Buy in Bulk: Purchasing rocks in bulk from a quarry or landscape supply store is typically cheaper than buying bagged rocks from a retail store.
- Choose Local Materials: Opting for rocks sourced locally reduces transportation costs, which can significantly lower the overall price.
- Consider Less Expensive Options: Gravel and crushed stone are generally more affordable than decorative rocks like river rock or flagstone. Consider using these in less visible areas or as a base material.
- DIY Installation: Installing the rocks yourself can save on labor costs, especially for smaller projects.
- Shop Around: Get quotes from multiple suppliers to compare prices and find the best deal.
- Plan Ahead: Avoid last-minute purchases, as prices may be higher during peak season. Planning your project in advance gives you time to shop around and take advantage of sales or discounts.
- Use Rocks Sparingly: Incorporate rocks strategically to highlight certain areas or features rather than covering the entire landscape. This reduces the amount of rock needed and lowers costs.
- Negotiate Prices: Don’t be afraid to negotiate with suppliers, especially for large orders. They may be willing to offer a discount to secure your business.
7. Where to Buy Landscaping Rocks?
