How to Install Stone Garden Edging Around a Patio

Stone edging is the difference between a patio that looks like it is floating in dirt and one that feels like a permanent, finished landscape feature. It acts as a structural anchor, keeping your pavers or concrete edges from shifting over time while preventing grass and mulch from encroaching onto your hardscape. When done well, the stone should sit flush with your existing patio surface or just a half-inch higher to allow for proper drainage without trapping water against your home. Building this requires more attention to the foundation than to the stone itself. If the ground underneath isn't stable, your beautiful edging will heave and tilt after the first winter freeze. Take your time during the excavation and compaction phases; a solid, level trench is the secret to a professional result that stands the test of time.

1. Map Your Edge Line. Mark the outer boundary of your edging using a garden hose or marking paint. Ensure the line is smooth and consistent, keeping it at a uniform distance from your patio edges.
2. Dig Deep and Straight. Dig a trench approximately 8 inches wide and 6 inches deep along your marked line. The floor of the trench should be flat and firm to provide a stable base for the base material.
3. Tamp That Gravel. Fill the trench with 3 inches of crushed gravel or paver base. Use a hand tamper to compact the gravel until it is rock-solid.
4. Bed Your Stones. Add a thin layer of stone dust or mortar to provide a setting bed for the stone units. This layer allows you to tweak the height and level of each stone individually.
5. Set Stone by Stone. Set the stones one by one, using a rubber mallet to tap them into the bed. Use a level to ensure every piece is perfectly aligned with the patio edge.
6. Pack and Seal. Backfill the space behind the stone edging with soil or decorative gravel. Pack it down firmly to eliminate gaps where weeds might take root.
