What Is Black Locust Lumber?

Black locust (Robinia pseudoacacia) is a hardwood that grows 40 to 60 feet tall and about 1 to 2 feet in diameter. They thrive in rich, moist soil with clear, straight bole or trunks in good areas. Black locust is rated the most environment-friendly wood with many excellent lumber attributes. It is rot-resistant, strong, dense, long-lasting, attractive, and non-toxic.

Black locust lumber is straight-grained with a medium texture. Generally, its lumber is average when it comes to workability. Despite the straight grain, locusts can be challenging to manage with hand and machine tools. Because of its high density and hardness, the wood is less workable than other hardwoods.

Where Is Locust Sourced From?

A variety of locusts grow in the central-eastern United States, but it is widely naturalized in temperate regions. It is native to Pennsylvania and the Appalachian Mountains and borders  southern Indiana, Oklahoma, and Georgia to Louisiana. Many of the trees escaped cultivation and thrive efficiently anywhere. According to new studies, black locust brings out hope for sustainable forestry in many of the world’s rainforests.

What to Look for When Buying Locust

Black locust is often marketed as solid lumber or veneer. For black locust lumber, choose the cut without sapwood and early growth. These yellowish parts are not as durable as the heartwood and are prone to decay, especially on the ground line. Locust lumber is subjected to low shrinkage upon drying, so medium kiln-dried to dried are the best options.
