Black Locust
Black locust wood for outdoor garden use — properties, comparisons, and buying guide.
This category covers black locust wood for outdoor garden use, including its properties and how it compares with other outdoor woods. Black locust heartwood is among the most durable domestic North American woods, and the articles explain what that means for raised beds, including how long they may last and how the EN 350 durability class system rates wood from Class 1 to Class 5.
The guides also compare black locust with ipe, long considered the benchmark for outdoor wood durability, and with cedar, white oak, and redwood. They list specifications such as Janka hardness, durability class, expected years outdoors, and price per board foot, and they describe black locust as a fast-growing tree native to Appalachia and the Ozarks.
