Will Burning Black Walnut Brush Kill The Juglone? Can I Use The Ash In My Compost?

Question

I’d like to know is Juglone survives burning and if I can use black walnut ashes in my compost.

Answer 1

There isn't much information on the subject. Juglone appears to have an incredibly high thermo-tolerance. I don't think it would survive burning, but any ash not thoroughly incinerated could harbor some of the herbicide.

I don't recommend it, but if you do then make sure it is thoroughly burned.
