Living retaining wall
While not a traditional retaining wall, this planted boulder erosion control incline, professionally installed by Rock Walls of Melbourne, Australia, blends in seamlessly with the rest of the backyard landscape.
The wall is made of large stacked basalt boulders, with trailing greenery interspersed to bring it to life. You might not have boulder-moving equipment handy, but consider adding climbing plants to an existing wall for a similar look.
Wood retaining wall
The beautiful colour of this cedar wood retaining wall by @tedmade.woodwork shows off the plants on both sides. A wood retaining wall is a more cost-effective choice than stone or concrete, but lacks the same longevity. The biggest concern is water, which will rot the wood if you don’t take the proper precautions. Use waterproof sheeting and gravel backfill to ensure proper drainage.
Concrete railroad tie retaining wall
Love the look of wood but prefer the strength of concrete? Consider concrete railroad ties. This retaining wall by @modern.landscape.solutions features precast concrete blocks that resemble timber railroad ties. A rustic look without the risk of wood rot — the best of both worlds.
