The Wood That Breaks Chainsaws (and Lasts 100 Years)

Описание: It breaks chainsaws. It poisons horses. It grows like a weed. But if you put a post of this wood in the ground today, your great-grandchildren will still be using it.
Meet Black Locust (Robinia pseudoacacia). Before pressure-treated pine and toxic chemicals took over the world, this was the gold standard for durability. It has a Janka hardness rating that puts Oak to shame and rot resistance that rivals concrete. There is an old farmer's saying: "Plant a stone and a Black Locust post. When the stone rots, replace the post."
So why can't you buy it at Home Depot?
In this video, I open the Garden Lore Vault to explain:
✅ The Physics: Why it creates sparks when you cut it.
✅ The Biology: How it pumps antifungal compounds into its own heartwood.
✅ The Curse: Why modern sawmills refuse to touch it (and why it's "crooked").
✅ The Danger: The toxic spikes that make it a fortress against livestock.
