What is the best wood to use for retaining walls?

By KC Eisenberg

Wood retaining walls provide structure, stability, and natural beauty to gardens and landscaping projects. They continue to be a popular choice because of the natural look they provide and because of their low price point, relative to expensive masonry and concrete retaining walls.

But there are so many options for choosing what wood to use for retaining walls. You know you want something durable, affordable, and non-toxic. But what?

Wood retaining walls must be:
  • Chemical free, not soaked in creosote or pressure-treatment chemicals
  • Extra durable in ground-contact settings
  • Non-toxic alternative to carcinogenic railroad ties
  • More affordable and longer lasting than cedar or redwood ties
  • Responsibly sourced
  • Beautiful!

Luckily, we have the perfect solution that fulfills all these criteria: our Restoration Juniper landscaping timbers.

Chemical-free: These untreated, completely natural timbers are ideal replacements for creosote-laden railroad ties and pressure-treated wood.

Extra durable: Juniper gets its remarkable durability from a high content of aromatic compounds that make the wood resistant to microbial decay for many decades. Juniper can last up to 30+ years in ground contact settings, according to studies from Oregon State University.

Affordable: Our juniper landscaping timbers are also far more affordable than using cedar or redwood, other long-lasting species that come with a high price tag. In fact, juniper lasts far longer than these species -- providing a lot more bang for your landscaping buck.

Responsibly sourced: Restoration Juniper landscaping timbers are sourced from grassland restoration projects in the high deserts of the West. Juniper is a native species, but decades of fire suppression and the unintended consequences of livestock grazing have allowed this species to grow unchecked, claiming millions of acres of sagebrush steppe and turning it into dense woodlands. These juniper woodlands suck up groundwater and are contributing to the decline of several key species, including the sage grouse. A collaborative group involving ranchers, loggers, environmentalists, and state government agencies is working together to harvest juniper trees, restore the grassland ecosystem and water supplies, and build a market for the wood. Your purchase of juniper lumber supports this effort.

Beautiful: Juniper also provides a rustic, organic look that is perfect for modern gardens and landscape design.
