The short answer
The best lawn edging for most yards is a spade-cut trench refreshed twice a year — free and clean. For a permanent border, steel edging and brick pavers set flush with the lawn are the two that survive mowers and string trimmers.

20+ year border that disappears visually and survives string trimmers.

The free option most pros use
A V-shaped trench cut with a half-moon edger or flat spade is what you see on well-kept estates. Cut 4–6 inches deep at a slight angle toward the bed, pull the sod strip, and mulch right up to the edge. It costs nothing, mowers ride it cleanly, and refreshing it takes 20 minutes per bed twice a season. The catch is purely that it's labor, twice a year.
If you want permanent: steel or flush-set pavers
Steel edging disappears visually, stops grass rhizomes cold, and shrugs off string trimmers — set it a half inch below the soil surface so the mower clears it. Flush-set brick or concrete pavers cost more in labor but give you a mow strip: one wheel rides the paver, no trimming pass needed. Both outlive every plastic product on the shelf.
Frequently Asked Questions
- What is the cheapest lawn edging that looks good?
- A spade-cut trench. It's free, looks sharp from day one, and is the standard on high-end properties. The only cost is recutting it twice a year.
- What edging can I mow over?
- Flush-set brick or concrete pavers and steel edging set below the surface. Both let a mower wheel ride the border so you skip the trimmer pass entirely.
- How deep should lawn edging be?
- 4–6 inches minimum to stop turf rhizomes from crossing into beds. Bermuda and other spreading grasses want the full 6 inches or a barrier that deep.
