How to install block landscape edging: A step-by-step guide to perfect your garden's borders

Installing block landscape edging is a practical way to define garden beds, walkways, or driveways, while giving your outdoor space a crisp, finished appearance. Here’s a straightforward guide:

1. Plan the Layout: Mark the area you want to edge using garden hose or string as a guide.
2. Excavate a Trench: Dig a trench along the outline, 4–6 inches deep and wide enough for your blocks.
3. Prepare the Base: Spread a 1–2 inch layer of sand or crushed stone aggregate in the trench, and tamp it down to ensure a stable foundation.
4. Set the Blocks: Lay the edging blocks in the trench, ensuring they’re level. Use a rubber mallet to adjust as needed. Stagger the joints for a professional look.
5. Backfill and Finish: Fill soil or mulch against the back of the blocks to hold them in place. Sweep sand or fine gravel between block joints for added stability.

As an interior designer, I recommend extending these neat, organized lines into your outdoor–indoor transition areas. If you’re planning to unify your home’s look inside and out, using a home designer tool can help you experiment with layouts, materials, and color schemes before installation. This ensures the landscape edging complements your overall design vision.

Tips 1:

For curved areas, use smaller blocks or specialty flexible edging blocks to achieve smooth, permanent curves without gaps. Always check the level as you go for a professional finish.
