Landscape edging around pool areas creates a clean, defined border between your lawn, mulch beds, and pool deck. Done well, it keeps grass from creeping onto concrete, stops mulch from washing into the pool, and makes the whole yard look finished. This guide walks through planning, materials, and installation so you can get that crisp line on the first try.
Plan the Edge Before You Dig
Start by marking the route with a garden hose or spray paint. Pool edges are rarely straight, so curves need a smooth arc rather than tight turns. Keep the edging at least 6 to 12 inches from the coping so you have room to work and to mow or trim without hitting the pool surround.

Check the drainage path before you commit. Edging can act as a dam, so leave gaps or install a small weep notch where runoff from the deck or lawn needs to escape. If the pool area sits on a slope, plan the edging to hold back soil on the downhill side rather than trapping water on the uphill side.
Choose Materials for Pool Conditions
Pool areas get splashed with chlorinated water, baked by sun, and walked on constantly. Pick materials that handle moisture and heat without warping or rusting. Steel and aluminum edging resist rot, while pressure-treated lumber and composite products suit a softer, more natural look. Avoid untreated wood in direct contact with pool water or wet soil, since it breaks down quickly.

Install the Edging Step by Step
- Mark the final line with spray paint and check the curve by eye from several angles.
- Cut a trench about 2 inches deep along the line, keeping the bottom level.
- Set the edging in the trench so the top sits about 1 inch above the surrounding soil or mulch.
- Secure the edging with stakes every 12 to 18 inches, driving them flush with the top edge.
- Backfill the outside of the edging with soil and tamp it firmly to prevent shifting.
- Check that the top line is consistent, then trim the grass or mulch to the edge.
On curves, bend flexible metal or plastic edging gradually and reinforce the inside arc with extra stakes. For timber or stone, the same principle applies: small, consistent sections look cleaner than one long piece forced into a tight curve.

Keep the Line Clean Over Time
Edging only looks sharp if you maintain it. Trim grass along the edge every few weeks during the growing season, and check stakes after heavy rain or freeze-thaw cycles, since they can heave loose. Rinse off pool chemical splashes from the edging promptly, especially on metal and wood, to slow corrosion and discoloration.
Common Mistakes
- Setting edging too close to the coping, which makes trimming awkward and can damage the pool surround.
- Skipping a drainage gap, causing water to pool behind the border.
- Using untreated wood in wet, chlorinated areas, which rots within a few seasons.
- Installing shallow or unstaked edging that heaves out of line after the first winter.
- Forcing rigid material into tight curves, which causes cracks and gaps.

FAQ
How far should landscape edging be from the pool?
Most installers leave 6 to 12 inches between the edging and the pool coping. That gap gives you room to trim and mow without damaging the pool surround.
Can I use wood edging around a pool?
Yes, but only pressure-treated or naturally rot-resistant wood, and keep it out of standing water. Untreated wood breaks down quickly in chlorinated, damp conditions.
Does pool edging need a drainage gap?
Often it does. Leaving a small gap or notch lets runoff from the deck or lawn drain away instead of collecting behind the border. For site-specific drainage needs, consider consulting a landscape professional.
Conclusion
Landscape edging around a pool takes careful planning, the right materials, and a shallow, level trench. Mark the line, set and stake the edging, and leave room for drainage and trimming. With a little upkeep, the border will keep its clean lines season after season.
