Landscape Edging Material Guide: Metal vs Plastic vs Stone vs Wood

Rubber (recycled segment) edging is typically made from reclaimed tire rubber, which does divert material from landfills, and it holds up well to UV exposure and freeze-thaw without becoming brittle the way plastic can. It's more flexible underfoot than rigid materials (an advantage for accidental foot or mower contact, since it flexes rather than cracks), though it generally costs more than plastic roll edging and doesn't hold as crisp a line as metal.

Wood timber edging is inexpensive, easy to install with basic tools, and gives a naturalistic, rustic look that pairs well with informal garden styles, but it's the shortest-lived common edging material — even pressure-treated wood typically needs replacement within roughly 5-10 years as it weathers, rots, or gets damaged by ground contact moisture and insects, compared to decades for brick, concrete, or stone options.

Unit-based edging (brick or paver set on end, or precast concrete edging blocks) offers the longest practical lifespan of any common edging option, since the units themselves are the same durable materials used for driveways and patios, and it can be installed without stakes at all since the units' own weight and mortar or sand-set base hold them in place. The trade-off is installation labor — each unit has to be individually set and leveled, which takes considerably longer than unrolling a length of flexible edging, and the material cost per linear foot is typically higher.

Natural stone edging (set on edge along the bed line) gives the most organic, high-end look of any edging option and, like brick or precast concrete, lasts essentially indefinitely once installed, since stone doesn't degrade from UV or moisture the way plastic or wood does. It's typically the most expensive material per linear foot and the most labor-intensive to install well, since natural stone pieces vary in size and shape and need individual fitting rather than uniform unit placement — it's the right choice when appearance and permanence matter more than installation speed or budget.

Flexible materials — plastic roll, metal coil, metal strip sections, and rubber segments — are all held in place with stakes driven through built-in stake channels or holes, since the material itself has no mass to resist being pushed or lifted. Unit-based materials — wood timber (sometimes staked, sometimes just set), brick/paver units, precast concrete blocks, and natural stone — rely primarily on their own weight, a compacted base, or mortar rather than staking, though timber is often still pinned with rebar stakes for extra stability on a slope.
