Home Depot landscape timbers are treated lumber pieces, typically made from pine or redwood, used to create borders around flower beds, gardens, and other landscape features. They are designed to resist rot and decay, making them durable in outdoor environments.
Landscape timbers are a popular choice for home gardeners and landscapers because they are relatively inexpensive, easy to install, and can create a visually appealing and functional border. Historically, landscape timbers were made from untreated wood, which made them susceptible to rot and decay. However, the development of pressure-treated lumber has greatly increased the lifespan of landscape timbers.
