Table of Contents

Landscape edging blocks are a fantastic way to define garden beds, create clean lines, and add visual appeal to your outdoor space. Whether you’re aiming for a formal garden or a more natural look, learning how to lay landscape edging blocks properly is essential for achieving a professional and long-lasting result. This comprehensive guide will walk you through each step, from planning and preparation to installation and finishing touches.

Planning Your Landscape Edging Project

Before you start digging, careful planning is key. Consider the following factors:

Define Your Purpose: What are you trying to achieve with your landscape edging? Are you containing mulch, defining a flower bed, or creating a border for a pathway? The purpose will influence the type of edging blocks you choose.
Choose the Right Blocks: Landscape edging blocks come in various materials (concrete, brick, stone), sizes, and styles. Select blocks that complement your existing landscape and suit your aesthetic preferences. Consider factors like durability, cost, and ease of installation.
Measure Your Space: Accurately measure the perimeter of the area you want to edge. This will help you determine the number of blocks you need. It’s always a good idea to purchase a few extra blocks to account for cuts and potential breakage.
Consider the Existing Landscape: Take into account the existing features of your yard, such as trees, shrubs, and slopes. Adjust your design as needed to accommodate these elements.
Check Local Codes and Regulations: Some municipalities have regulations regarding landscaping features. Check with your local authorities to ensure your project complies with all applicable codes.

Gathering Your Materials and Tools

Having the right tools and materials on hand will make the installation process much smoother. Here’s a list of what you’ll need:

Landscape Edging Blocks: The quantity determined by your measurements, plus a few extras.
Shovel: For digging the trench.
Spade: For fine-tuning the trench edges.
Level: Essential for ensuring your edging is straight and even.
Rubber Mallet: For gently tapping the blocks into place.
Measuring Tape: For accurate measurements.
Landscape Fabric: To prevent weed growth beneath the edging.
Gravel or Crushed Stone: For creating a stable base.
Sand: For leveling the blocks.
Gloves: To protect your hands.
Safety Glasses: To protect your eyes from debris.
Wheelbarrow: For moving materials.
String Line and Stakes: To create a straight line for your edging.
Circular Saw with Masonry Blade (Optional): For cutting blocks to fit.

Preparing the Site

Proper site preparation is crucial for a successful installation. Follow these steps:

Mark the Area: Use stakes and string to mark the perimeter of your edging. This will serve as a guide for digging your trench.
Dig the Trench: Dig a trench along the marked line. The depth of the trench should be deep enough to accommodate a layer of gravel or crushed stone, a layer of sand, and the height of the landscape edging blocks. Typically, a depth of 6-8 inches is sufficient. The width of the trench should be slightly wider than the width of the blocks.
Compact the Soil: Use a hand tamper or plate compactor to compact the soil at the bottom of the trench. This will provide a stable base for your edging.
Install Landscape Fabric: Line the trench with landscape fabric to prevent weed growth. Overlap the edges of the fabric to ensure complete coverage.
Add Gravel or Crushed Stone: Pour a layer of gravel or crushed stone into the trench, about 2-3 inches thick. This will improve drainage and provide a solid foundation for the blocks.
Level the Base: Use a rake to level the gravel or crushed stone.
Add Sand: Pour a thin layer of sand (about 1 inch) over the gravel or crushed stone. This will provide a leveling bed for the blocks.

Laying the Landscape Edging Blocks

Now comes the exciting part: laying the landscape edging blocks! Follow these steps carefully:

Position the First Block: Place the first block at one end of the trench, ensuring it is level and aligned with the string line.
Level the Block: Use a level to check that the block is level both horizontally and vertically. Adjust the sand beneath the block as needed to achieve a level surface.
Secure the Block: Gently tap the block into place with a rubber mallet. Avoid hitting the block too hard, as this could damage it.
Continue Laying Blocks: Continue laying blocks along the trench, one at a time, ensuring each block is level and aligned with the string line. Use a level to check the alignment of each block with the adjacent blocks.
Cut Blocks as Needed: If you need to cut blocks to fit around corners or other obstacles, use a circular saw with a masonry blade. Always wear safety glasses when cutting blocks.
Fill Gaps: Once all the blocks are in place, fill any gaps between the blocks with sand. Use a broom to sweep the sand into the gaps.

Finishing Touches

After laying the landscape edging blocks, add the finishing touches to complete the project:

Backfill the Trench: Backfill the trench behind the edging blocks with soil. Compact the soil to provide additional support for the blocks.
Add Mulch or Gravel: Add mulch or gravel to the area enclosed by the edging blocks. This will help to suppress weed growth and add visual appeal.
Water the Area: Water the area thoroughly to help settle the soil and sand.
Inspect and Adjust: Inspect the edging for any unevenness or gaps. Make any necessary adjustments to ensure a clean and professional finish.

Tips for Success

Use a string line: A string line is essential for creating a straight and even edging.
Take your time: Don’t rush the installation process. Take your time to ensure each block is level and aligned.
Use a rubber mallet: A rubber mallet will help you avoid damaging the blocks.
Check for level frequently: Check the level of each block frequently to ensure a consistent finish.
Consider using edging adhesive: For added stability, consider using landscape edging adhesive to secure the blocks together. This is especially useful for curved or irregular edging.
Proper Drainage Ensure proper drainage behind the landscape edging blocks to prevent water buildup and potential damage from freezing and thawing. This can be achieved by sloping the ground away from the edging or installing a drainage system.
Choose the right mortar (if applicable): If you are using mortar to secure your landscape edging blocks, choose a mortar specifically designed for outdoor use and that is compatible with the material of your blocks. Follow the manufacturer’s instructions carefully.

Maintaining Your Landscape Edging

Once your landscape edging blocks are installed, proper maintenance will help keep them looking their best for years to come. Here are a few tips:

Regular Cleaning: Periodically clean the edging blocks with a brush and water to remove dirt, debris, and algae.
Weed Control: Regularly remove any weeds that grow near the edging.
Re-leveling: Over time, the blocks may settle or shift. Re-level them as needed by adding sand beneath the blocks.
Repairing Cracks: If any of the blocks crack or break, replace them promptly to prevent further damage.

Troubleshooting Common Problems

Even with careful planning and execution, you may encounter some common problems when laying landscape edging blocks. Here are a few solutions:

Uneven Edging: If the edging is uneven, check the base for inconsistencies. Add or remove sand as needed to level the blocks.
Gaps Between Blocks: If there are gaps between the blocks, try using a smaller block or cutting a block to fit the space. You can also fill the gaps with sand or mortar.
Blocks Shifting: If the blocks are shifting, ensure the base is properly compacted and consider using landscape edging adhesive to secure the blocks in place.
Weed Growth: If weeds are growing through the landscape fabric, ensure the fabric is properly installed and overlapped. You may also need to apply a weed killer to the area.

Conclusion

Learning how to lay landscape edging blocks is a rewarding project that can significantly enhance the beauty and functionality of your outdoor space. By following these steps and tips, you can achieve a professional-looking result that will last for years to come. Remember to plan carefully, gather the right tools and materials, and take your time during the installation process. With a little effort, you can transform your yard into a stunning oasis. Consider exploring different types of landscape edging blocks to find the perfect fit for your style and budget. Good luck, and happy landscaping!
