How to Install Permanent Garden Bed Edging

Landscape edging is the difference between a garden that looks wild and one that looks curated. By installing a physical barrier, you stop turf grass from invading your flower beds and ensure that mulch stays where you put it rather than migrating onto your walkways or lawn. Done well, permanent edging provides a clean, architectural line that serves as the backbone of your exterior design. Whether you choose heavy-duty steel, stone, or pavers, the secret to longevity isn't just the material itself, but the depth and stability of the foundation you build beneath it.

1. Mark Your Lines First. Lay out a garden hose or string line to define the curve or straight line of your bed. Spray paint the ground along the line so you have a clear guide for digging.
2. Dig Deep and Straight. Dig a trench along your marked line that is roughly 4 to 6 inches deep and slightly wider than your chosen edging material. Keep the inside wall of the trench vertical and clean for a tight fit.
3. Tamp It Solid. Pour a 1-inch layer of crushed stone or coarse sand into the bottom of the trench. Use a hand tamper or a block of wood to pack it down until it is firm and level.
4. Set and Level. Place your edging sections into the trench, checking for level as you go. Connect adjacent pieces according to the manufacturer's instructions, ensuring a snug, flush joint.
5. Pin It Down. Drive landscape spikes or stakes through the pre-drilled holes in the edging at a slight inward angle. This prevents the material from pulling away from the soil over time.
6. Lock It In. Push the excavated soil back against both sides of the edging to lock it in place. Tamp the soil firmly, then spread mulch on the bed side to mask the transition.
