Tolerates wide range of soil conditions- not a picky plant Canopy Layer Silvopastures with Black Locust can provide posts and firewood while improving the forage for your animals. An acre of Black Locust is said to produce 800 to 1200 pounds of honey. Moreover, the Black Locust blooms late enough in spring that the blossoms are rarely damaged by frost; thus, it is a reliable annual source for bees. Black Locust has a spot in your permaculture, resilient, and sustainable homestead. The edibility is not the major attribute of this tree. While the flowers are sweet and tasty, especially when dipped and fried like fritter, the big value is in the wood. Both fast growing and strong. Black Locust wood is rot resistant and a great choice for fence posts. Firewood from this tree burns slowly and has a heat value higher than beech or maple. The tree can be coppiced to encourage branching which can then be harvested on a rotational basis. Renewable energy!
