* **Garden Hose with Spray Nozzle:** For wetting down the rock to settle it and reveal its true color.

Step-by-Step Installation Guide

Follow these steps for a successful landscape rock installation:

**Step 1: Prepare the Area**

* **Clear the Area:** Remove all existing vegetation, debris, rocks, and roots from the area you plan to cover. This is crucial for preventing weed growth and ensuring a smooth, even surface.
* **Level the Ground:** Use a shovel and rake to level the ground as much as possible. Fill in any low spots and remove any high spots. A level surface is essential for even rock distribution and proper drainage.
* **Grade the Soil (If Necessary):** If you’re installing rock for drainage purposes, such as around a foundation or in a low-lying area, grade the soil to slope away from the structure or towards a drainage outlet. A gentle slope of 1-2% is usually sufficient.
* **Compact the Soil (Optional):** For pathways and driveways, compacting the soil before laying the weed barrier will provide a more stable base. Use a tamper or plate compactor to compact the soil in layers.

**Step 2: Install the Edging (Optional)**

* **Position the Edging:** Place the edging material around the perimeter of the area you’re covering, following the desired shape and design.
* **Secure the Edging:** Depending on the type of edging, you may need to use stakes, pins, or concrete to secure it in place. Follow the manufacturer’s instructions for installation.
* **Ensure Proper Height:** Make sure the edging is slightly higher than the surrounding ground level to prevent rock from spilling over.

**Step 3: Lay the Weed Barrier Fabric**

* **Unroll the Fabric:** Unroll the weed barrier fabric over the prepared area, overlapping the edges by at least 6 inches. This overlap prevents weeds from growing through the seams.
* **Cut the Fabric:** Use a utility knife or scissors to cut the fabric to fit the area, leaving a few inches of excess around the edges.
* **Secure the Fabric:** Use landscaping staples or pins to secure the fabric to the ground, spacing them every 1-2 feet along the edges and in the middle of the fabric. Make sure the staples are driven deep into the soil to prevent the fabric from lifting.
* **Cut Holes for Plants (If Necessary):** If you’re installing rock around existing plants, cut holes in the fabric to accommodate the plants. Make the holes slightly larger than the base of the plants to allow for growth.

**Step 4: Distribute the Landscape Rock**

* **Load the Wheelbarrow:** Fill the wheelbarrow with landscape rock. Avoid overloading the wheelbarrow to prevent spills and make it easier to maneuver.
* **Dump the Rock:** Carefully dump the rock in small piles evenly across the area you’re covering. This will help distribute the weight and prevent damage to the weed barrier fabric.
* **Spread the Rock:** Use a shovel and rake to spread the rock evenly over the area, aiming for the desired depth. Avoid piling the rock too high in any one area.
* **Work in Sections:** If you’re covering a large area, work in sections to ensure even distribution and avoid fatigue.

**Step 5: Level and Smooth the Rock Surface**

* **Use a Rake:** Use a rake to level and smooth the rock surface, removing any large clumps or uneven areas. A leaf rake is helpful for this step because it’s lighter and easier to maneuver.
* **Check for Even Coverage:** Inspect the area to ensure that the rock is evenly distributed and that the weed barrier fabric is completely covered. Add more rock as needed to fill in any thin spots.
* **Use a Level (For Pathways):** If you’re installing rock for a pathway, use a level to ensure that the surface is even and sloped slightly for drainage.

**Step 6: Fine-Tune the Design**

* **Arrange Larger Rocks (If Applicable):** If you’re using larger rocks or boulders as focal points, arrange them in the desired positions. Consider the overall aesthetic and the natural flow of the landscape.
* **Create Pathways or Patterns:** If you’re creating pathways or patterns with the rock, use a rake or your hands to define the edges and create the desired shapes.
* **Add Decorative Elements (Optional):** Add decorative elements such as statues, planters, or lighting to enhance the visual appeal of the landscape.

**Step 7: Clean Up and Finishing Touches**

* **Remove Debris:** Remove any debris, such as leaves, twigs, or construction materials, from the area.
* **Wet Down the Rock:** Use a garden hose with a spray nozzle to wet down the rock. This will help settle the rock and reveal its true color. It also helps wash away any dust or dirt accumulated during installation.
* **Inspect and Adjust:** Take a final look at the completed landscape and make any necessary adjustments. Add more rock to fill in any thin spots, rearrange rocks for a more pleasing aesthetic, and ensure that the edging is secure.
