About Black Locust

Black Locust (robinia pseudoacacia) is classified by the USDA as “strong, hard and extremely durable.” It has been utilized for fencing, mine timbers, landscaping, and waterscaping in the US for over 100 years. The upfront investment is worth it because finishes and other treatments are not necessary to ensure the longevity of your project even in the wettest conditions. 

Black Locust is an industry leader for sustainable building materials. Compared to pressure treated lumber of all kinds, Black Locust is a superior choice. Black Locust's longevity and durability is provided by nature! Black Locus is:

  • Naturally rot resistant and can outlast treated lumber by 60-80 years!
  • Cleaner and more environmentally friendly than pressure treated lumber, which is created with a cocktail of dangerous chemicals and has a high embodied energy!
  • A cost effective way to meet Organic Certification in agricultural contexts when installing fencing, poles, and raised beds!
  • The Wood that built Colonial America and Leland's Fish Town!
  • Cost competitive with cedar, redwood, Brazilian Ipe, and other tropical hardwoods in its rough

Best of all: Purchases through SEEDS support our mission.

Where do we get our Black Locust?

Black Locust is an extremely aggressive grower and, in Michigan, is frequently considered an invasive species. We love sourcing local materials and Black Locust in particular lets us tangibly demonstrate to our EcoCorps crew members a full product life cycle going from living tree to milled lumber and then becoming a boardwalk pathway back into nature.

Hire SEEDS Youth Corps for Installation

An extremely dense wood, Black Locust can also be unusual to work with if you are used to pine and even hard maple. Tough fibers require a few key tools and techniques during installation.

SEEDS EcoCorps specializes in working with Black Locust and your purchases will also directly support youth and project initiatives.
