Pergolas, Arbors and Trellises
Black Locust wood makes an excellent material for pergolas, arbors and trellises. It requires very little if any maintenance and lasts for 50+ years without any decay. Black Locust wood will outlast pressure treated lumber with none of the harmful chemicals used with pressure treated lumber. It will last longer than the tropical hardwoods without the environmental destruction and with a fraction of the carbon footprint necessary to turn it into a finished wood product.

We made all the support columns and support cross members of this pergola from black locust lumber.
Black Locust wood has many uses in the garden. As you can see from this picture Black locust was used for the pergola support structure, as well as the decking, planters and fencing.
