1. Understanding Black Lava Rock
Before diving into where to purchase black lava rock, it’s helpful to understand what it is and why it’s a popular choice for landscaping.
1.1. What is Black Lava Rock?
Black lava rock is formed from cooled molten lava. Its unique porous texture comes from gases that were trapped within the lava as it solidified. This makes it lightweight and allows for excellent drainage. According to Arizona State University’s School of Earth and Space Exploration, the dark color comes from its high iron and magnesium content.
1.2. Benefits of Using Black Lava Rock in Landscaping
Black lava rock offers a multitude of benefits, making it a favorite among homeowners, landscapers, and designers.
- Aesthetic Appeal: Its deep black color provides a striking contrast to greenery and other landscape elements.
- Excellent Drainage: The porous nature of lava rock allows water to drain quickly, preventing waterlogging and root rot.
- Weed Control: It acts as a natural weed barrier, suppressing weed growth and reducing the need for herbicides.
- Low Maintenance: Lava rock is durable and doesn’t decompose, meaning less frequent replacement compared to mulch.
- Insulation: It helps regulate soil temperature, keeping roots cooler in the summer and warmer in the winter.
- Fire Resistance: Being a volcanic rock, it’s naturally fire-resistant, making it ideal for fire pits and areas prone to wildfires.
1.3. Common Uses of Black Lava Rock in Landscaping
Black lava rock is versatile and can be used in a variety of landscaping applications.
- Xeriscaping: Perfect for dry landscapes, it reduces water usage while providing a visually appealing ground cover.
- Fire Pits and Fireplaces: Its fire resistance makes it a safe and attractive option for fire features.
- Garden Beds: Enhances plant display, provides drainage, and helps retain moisture.
- Pathways and Walkways: Offers a unique and durable surface for garden paths.

3. Factors to Consider When Buying Black Lava Rock

Look for rocks that are consistent in color and size. Avoid rocks that are crumbling or have excessive dust, as this can indicate poor quality.
3.2. Size and Shape
Black lava rock comes in various sizes and shapes. Choose the size that best suits your intended use. Smaller rocks are ideal for garden beds and pathways, while larger rocks can be used as focal points or for erosion control.
3.3. Quantity Needed
Calculate the amount of rock you need based on the area you want to cover and the desired depth. Most suppliers can help you estimate the quantity needed. As Robert P. mentioned in his review, it’s wise to order slightly more than you think you need.
3.4. Price per Ton or Cubic Yard
Compare prices per ton or cubic yard to ensure you’re getting the best deal. Factor in delivery costs when comparing prices from different suppliers.
3.5. Delivery Options and Costs
Check the delivery options and associated costs. Some suppliers offer free delivery within a certain radius, while others charge a fee based on distance and quantity.

5. How to Estimate the Amount of Black Lava Rock You Need
Estimating the correct amount of black lava rock is essential to avoid over or under-ordering. Here’s a step-by-step guide:
5.1. Measure the Area
Measure the length and width of the area you want to cover in feet. Multiply these two numbers to get the area in square feet.
5.2. Determine the Desired Depth
Decide how deep you want the lava rock to be. A depth of 2-3 inches is generally recommended for garden beds and pathways.
5.3. Use a Coverage Calculator
Many suppliers offer online coverage calculators. Input the area in square feet and the desired depth in inches, and the calculator will estimate the amount of rock needed in cubic yards or tons.
5.4. Manual Calculation
If a calculator isn’t available, you can calculate manually:
- Convert the depth from inches to feet by dividing by 12.
- Multiply the area in square feet by the depth in feet to get the volume in cubic feet.
- Convert cubic feet to cubic yards by dividing by 27 (since there are 27 cubic feet in a cubic yard).
- To convert cubic yards to tons, multiply by the weight of lava rock per cubic yard (typically around 1,000-1,300 pounds per cubic yard) and divide by 2,000 (since there are 2,000 pounds in a ton).
5.5. Account for Irregular Shapes
For irregular shapes, break the area into smaller, more manageable sections. Calculate the area of each section and add them together.
5.6. Add Extra for Safety
It’s always a good idea to add 5-10% extra to account for settling, uneven spreading, and waste. As Robert P. suggested, it’s better to have a little extra than to run short in the middle of your project.
6. Preparing Your Site for Black Lava Rock
Proper site preparation ensures the longevity and effectiveness of your black lava rock installation.
6.1. Clear the Area
Remove any existing vegetation, rocks, debris, and weeds from the area. Level the ground to create a smooth surface.
6.2. Install Weed Barrier Fabric
Lay down a high-quality weed barrier fabric to prevent weeds from growing up through the lava rock. Overlap the edges of the fabric by at least 6 inches and secure it with landscape staples.
6.3. Edge Restraints
Consider installing edge restraints, such as plastic edging, metal edging, or paver stones, to contain the lava rock and prevent it from spreading.
6.4. Soil Amendment (Optional)
If you’re using lava rock in a garden bed, consider amending the soil with compost or other organic matter to improve drainage and fertility.
7. Installing Black Lava Rock: A Step-by-Step Guide
Installing black lava rock is a straightforward process that can be done by most homeowners.
7.1. Spread the Rock
Using a wheelbarrow and shovel, spread the lava rock evenly over the prepared area.
7.2. Rake the Rock
Use a rake to distribute the rock evenly and create a uniform surface.
7.3. Adjust the Depth
Check the depth of the rock in various areas and add or remove rock as needed to achieve the desired depth.
7.4. Compact the Rock (Optional)
For pathways and walkways, you may want to compact the rock using a plate compactor or hand tamper to create a more stable surface.
7.5. Water the Rock (Optional)
Watering the rock can help settle it and wash away any dust or debris.

8.4. Clean the Rock Periodically
If the rock becomes stained or dirty, you can clean it with a garden hose or pressure washer.
8.5. Avoid Over-Watering
While lava rock provides excellent drainage, avoid over-watering plants in areas covered with lava rock, as this can lead to mineral buildup and discoloration.
