What to Put Under Landscape Rock: A Comprehensive Guide

Choosing the right base for your landscape rocks is crucial for their longevity and the overall aesthetic appeal of your garden. Simply placing rocks directly on soil is a recipe for settling, weed growth, and an uneven look. This comprehensive guide will explore the best materials to use as a base, addressing common concerns and offering professional tips for a stunning and long-lasting result.

Why You Need a Base Under Landscape Rock

A proper base serves several critical functions:

• Weed Suppression: A weed barrier prevents unwanted plants from sprouting through the rocks, saving you time and effort on weeding.
• Drainage: Good drainage prevents waterlogging, which can lead to rock settling and erosion. It also protects the underlying soil from becoming waterlogged.
• Stability: A solid base prevents the rocks from sinking into the soil, ensuring a level and even surface. This is especially important for larger rocks and heavier installations.
• Leveling: The base allows for leveling uneven ground, creating a professional and polished look.
• Erosion Control: A well-constructed base helps prevent erosion of the soil beneath the rocks, especially on slopes.

Best Materials for Under Landscape Rock

Several materials are suitable for creating a base under landscape rocks, each with its own advantages and disadvantages:

1. Landscape Fabric (Weed Barrier):

• Pros: Excellent weed suppression, relatively inexpensive, allows for drainage.
• Cons: Can degrade over time, especially if exposed to UV light. May not be suitable for all soil types.
• How to Use: Overlap edges and secure with landscaping staples or pins.

2. Gravel:

• Pros: Excellent drainage, relatively inexpensive, readily available.
• Cons: Can be messy to install, might not provide sufficient weed suppression on its own.
• How to Use: Use a layer of 1-2 inches of gravel, depending on the size of your rocks and soil conditions.

3. Crushed Stone:

• Pros: Excellent drainage, durable, provides a stable base.
• Cons: Can be more expensive than gravel, may require more effort to level.
• How to Use: Use a layer of 2-4 inches, depending on the size of your rocks and soil conditions.

4. Geotextile Fabric:

• Pros: High-strength weed barrier, excellent drainage, long-lasting.
• Cons: Can be more expensive than landscape fabric.
• How to Use: Similar to landscape fabric, overlap edges and secure.

5. A Combination Approach:

For optimal results, consider combining materials. For example, using a layer of geotextile fabric followed by a layer of gravel provides excellent weed suppression and drainage.

Step-by-Step Guide to Installing Landscape Rock

1. Prepare the Area: Clear the area of weeds, grass, and any debris.
2. Level the Ground: Use a rake or shovel to level the ground as much as possible.
3. Install Weed Barrier (Optional): Lay down your chosen weed barrier, overlapping edges by at least 6 inches. Secure with staples or pins.
4. Add Base Material: Spread your chosen base material (gravel, crushed stone, etc.) evenly over the area. The depth will depend on the size and weight of your rocks and soil conditions. Aim for at least 2-4 inches.
5. Level the Base: Use a rake or level to ensure the base is even.
6. Place the Rocks: Carefully place your rocks, arranging them to your liking.
7. Add Topdressing (Optional): A thin layer of gravel or pea gravel can be added between the rocks to fill gaps and enhance the aesthetic appeal.

Choosing the Right Rock Size and Type

The size and type of rock you choose will also influence your base material selection. Larger, heavier rocks require a more substantial base for stability.

Maintaining Your Landscape Rock

Regularly inspect your landscape rock installation for any signs of settling or weed growth. Addressing any issues promptly will help maintain the look and integrity of your landscape.

By following these guidelines and choosing the appropriate materials for your specific needs, you can ensure your landscape rocks remain beautiful and functional for years to come. Remember to consider your local climate and soil type when making your decisions. Happy landscaping!
