How Much Does A Large Rock Cost for landscaping? Large rocks, also known as landscape boulders, typically cost $120 to $350 per ton or $50 to $160 per cubic yard, depending on their size, type, and quantity. At rockscapes.net, we provide comprehensive guidance on selecting the right boulders to elevate your outdoor space with natural beauty and functionality, along with expert advice and a wide selection to suit any landscaping project. For those who prefer individual stones, expect to pay anywhere from a few dollars for smaller 10-inch rocks, to upwards of $2,300 for very large boulders exceeding 48 inches.
1. Understanding Landscape Boulder Costs
The cost of landscape boulders can vary significantly. The cost of landscape boulders vary based on several key elements, including the quality, type, and the distance they need to be transported. Let’s break down these factors.
1.1. Size and Quality
The size of the landscape boulder is a primary cost driver.
| Stone Size | Single Stone Cost |
|---|---|
| 10″ | $3 – $7 |
| 12″ | $5 – $15 |
| 18″ | $12 – $35 |
| 24″ | $35 – $90 |
| 30″ | $50 – $175 |
| 36″ | $100 – $350 |
| 48″ | $150 – $650 |
| > 48″ | $600 – $2,300 |
Larger boulders over 36 inches are more challenging to quarry and transport, leading to higher prices. Smaller rocks are less expensive and can be delivered in bulk, reducing the per-stone cost. High-quality stones with smooth textures and unique aesthetic appeal also command higher prices. According to research from Arizona State University’s School of Earth and Space Exploration, the availability of certain rock types in specific regions greatly influences their cost due to transportation expenses.
1.2. Stone Type
The type of stone also affects the cost. Common types include:
- Granite
- Limestone
- Sandstone
- Basalt/Lava Rock
- Gneiss
Due to their weight and the high cost of transportation, some stone types are only available in certain regions. Prices are typically lowest for stones quarried locally.
1.3. Quantity
Most suppliers price landscape boulders by the ton, although some price smaller stones by the cubic yard or pallet. Minimum order sizes may apply, so it’s essential to confirm this with your supplier. Buying in larger quantities can sometimes reduce the cost per ton or yard, but it depends on the supplier’s pricing structure.
1.4. Delivery Fees
Delivery costs can range from $50 to $400 or more, depending on the distance and the size and weight of the stones.

Delivery fees can add a significant cost to your project, especially if you are ordering from a supplier far from your location.
1.5. Site Preparation and Installation
The cost of site preparation and installation varies based on the complexity of the project. Simple placement of a few small boulders is relatively inexpensive, while creating retaining walls or complex rock arrangements requires professional expertise and specialized equipment, increasing the overall cost.
2. Factors Influencing the Price of Large Rocks
Several factors can impact the price of large rocks, making it essential to consider these aspects when planning your landscaping project.
2.1. Quarry Location
The location of the quarry significantly affects the price. If the quarry is far from your property, transportation costs will increase the overall expense. Local quarries usually offer better prices due to reduced transportation costs. At rockscapes.net, we source our stones from local quarries whenever possible to offer competitive pricing to our customers.
2.2. Accessibility
Accessibility to the installation site also influences the price. If the site is difficult to access, requiring specialized equipment or manual labor, the installation costs will increase. Ensure the delivery path is clear and accessible to avoid additional charges.
2.3. Rock Shape and Texture
The shape and texture of the rocks play a role in pricing. Uniquely shaped or textured rocks are more valuable due to their aesthetic appeal. Smooth, uniform rocks may be cheaper, but they might not provide the same visual interest as more distinctive stones.
2.4. Seasonal Demand
Seasonal demand can also affect prices. During peak landscaping seasons (spring and summer), demand for rocks increases, potentially driving up prices. Planning your project during off-peak seasons may help you secure better deals.
3. Types of Large Rocks and Their Costs
Different types of large rocks come with varying costs. Understanding the characteristics and prices of each type helps you make an informed decision.
3.1. Granite Boulders
Granite boulders are durable and aesthetically pleasing, making them a popular choice for landscaping. They range from $150 to $400 per ton, depending on size and color. Granite is known for its resistance to weathering, making it ideal for long-term landscaping projects.
3.2. Limestone Boulders
Limestone boulders offer a classic, natural look and are often used for retaining walls and decorative features. Limestone costs between $120 and $350 per ton. However, limestone can be susceptible to erosion in acidic environments.
3.3. Sandstone Boulders
Sandstone boulders are known for their warm colors and layered appearance, adding a unique touch to any landscape. They typically cost $100 to $300 per ton. Sandstone is relatively soft, so it may not be suitable for high-traffic areas.
3.4. Basalt Boulders
Basalt boulders, also known as lava rocks, provide a dark, dramatic look and are often used in modern landscaping designs. Basalt costs between $180 and $450 per ton. Basalt is highly durable and resistant to temperature changes.
3.5. Fieldstones
Fieldstones are naturally weathered rocks collected from fields and riverbeds. Their irregular shapes and varied colors make them a great choice for naturalistic landscapes. Fieldstones range from $80 to $250 per ton, making them one of the more affordable options.
4. Determining the Quantity of Large Rocks Needed
Calculating the amount of large rocks required for your project is crucial to avoid overspending or running short.
4.1. Measuring the Area
Start by measuring the area where you plan to place the rocks. Calculate the length, width, and desired depth of the rock placement. Use these measurements to estimate the volume of rocks needed.
4.2. Estimating Volume
To estimate the volume, multiply the length, width, and depth. For example, if you want to cover an area that is 10 feet long, 5 feet wide, and 1 foot deep, the volume would be 50 cubic feet.
4.3. Converting to Weight
Most suppliers sell rocks by the ton. Convert the volume to weight by considering the density of the rock type. The density of rocks varies, but a general estimate is around 100 pounds per cubic foot. Therefore, 50 cubic feet of rocks would weigh approximately 5,000 pounds, or 2.5 tons.
4.4. Consulting with Professionals
If you’re unsure about the calculations, consult with a landscaping professional. They can provide accurate estimates based on your specific project requirements and help you avoid costly mistakes. At rockscapes.net, our experts are always available to assist you with these calculations.
5. Where to Buy Large Rocks
Knowing where to purchase large rocks ensures you get the best quality and price.
5.1. Local Quarries
Local quarries often offer the best prices and a wide selection of rocks. Buying directly from a quarry can save you money on transportation costs. Visit the quarry to inspect the rocks and discuss your project needs with their experts.
5.2. Landscape Supply Stores
Landscape supply stores are another excellent option. They typically offer a variety of rock types and sizes, along with other landscaping materials. These stores often provide delivery services, making your project more convenient.
5.3. Home Improvement Stores
Large home improvement stores like Home Depot and Lowe’s also sell landscape rocks. While their selection may be limited compared to quarries and landscape supply stores, they offer convenience and competitive pricing.
5.4. Online Suppliers
Online suppliers provide a convenient way to purchase rocks, especially if you need specific types or sizes. However, be sure to factor in shipping costs, which can be substantial for heavy items like rocks.
6. Installation Tips for Large Rocks
Proper installation ensures the longevity and aesthetic appeal of your rock landscape.
6.1. Site Preparation
Prepare the site by clearing any vegetation, debris, and existing structures. Level the ground and ensure proper drainage to prevent water accumulation around the rocks.
6.2. Safety Measures
Prioritize safety when handling large rocks. Wear safety gloves, sturdy shoes, and eye protection. Use appropriate equipment like dollies, forklifts, or cranes to move heavy rocks.
6.3. Placement Techniques
Place the rocks strategically to achieve the desired aesthetic effect. Consider the size, shape, and texture of each rock. Arrange the rocks in a natural-looking pattern, avoiding straight lines or symmetrical arrangements.
6.4. Securing the Rocks
Secure the rocks to prevent them from shifting or toppling over time. Use smaller rocks or gravel to stabilize the base of larger rocks. For retaining walls, ensure proper backfilling and drainage to prevent structural issues.
7. Landscape Design Ideas with Large Rocks
Large rocks can be used in various landscape designs to create stunning visual effects.
