Plant Uses

Black locust is very heavy, very hard, and exceedingly strong and stiff. It has very high shock resistance, high nail-holding qualities, and good durability and decay resistance. It is moderately low in shrinkage and turns well although it is generally difficult to work with hand tools. Locust is used for fence posts, poles, ties, mine timbers, and stakes. It is also used for boxes, crates, woodenware, and novelties. Sound, straight pieces are prized for use in pole-type barns.
