Naturally Rot-resistant Woods — 4 Comments

  1. I understand there is a “ship mast” form of Black Locust. It has a very straight growing trunk. It is, or was , planted widely in Hungary I believe. This form also had less thorns. An older gentleman once told me you had to work it while green. This, he said, was due to the fact it becomes as hard as iron once fully seasoned. I have not had the chance to work with any so it is only secondhand information. Thank you for a very interesting read each day.

    • Thanks, that’s interesting. I did read where lots have black locust trees have been planted in Hungary and the surrounding area. I wonder how many are ship mast type trees?

      Update: One article says there are 4 million hectares of black locust trees in Hungary. They have 250 years of research and propagation of trees with superior traits.

      “The primary use of black locust wood has been for fence posts which, due to flavonoids in the heartwood, can endure for over 100 years in the soil… Widely used for erosion control and reforestation, black locust is ideally suited for woody biomass plantings, and commercial energy production may eventually become one of its primary uses in the U.S. Its virtues include nitrogen fixing ability, inexpensive propagation by seed, rapid vegetative propagation, adaptability to a wide range of site conditions, rapid juvenile growth, high heat content of the wood, and prolific regrowth after cutting (Miller et al. 1987).”

      This looks like a US forum and they may not know the details about black locust trees in Hungary where they’re intensively researching and propagating these trees.

  2. Interesting info on the Black Locust. Would never have thought the wood was good for much other then burning. I would add that do not plant anywhere close to garden or landscaped areas. Black Locust are invasive, send up suckers, and have and abundant amount of litter. They form seed pods and the blossoms are allergenic. Maybe a great tree for the back 40 that is to be harvested, but not something you would want to intentionally plant near a residence. In California they are found all over the high desert areas. They are a nuisance tree comparable with the Siberian Elm and Cottonwood..They are prolific and fast growing.They are a member of the legume family and can fix nitrogen in poor soils. Black Locust roots spread out and can send up suckers 50-60 ft away from the tree..
