Thanks for the info.
Sounds like the black locust needs to be on a property boundary or in a fence row.
One thing you might not know about the mimosa (lead tree, luecaena) is that it is a nitrogen fixer, which is why I wanted to use it. I have seen videos (Backyardfoodproduction.com) where they plant the mimoso between the rows in their garden to act as fertilizer. You can also cut the trees back to nearly nothing before winter, and till the organic matter into the soil, or feed the leaves & pods to rabbits.
LOL, yeah, we had a clump of mimosa trees in a side yard when I was a kid. My dad would practically whack them down to stumps every year and we were climbing them again the next year. We loved them particularly for the flexibility ... you could hang on the limbs or ride them like a bucking pony. :)
