Longevity of juglone
We are in the process of demolishing a large shed which stood right
beside a very large black walnut tree. There are probably many
hundreds of pounds of compost on the roof of the shed, mainly from the
black walnut husks, leaves, etc.
Any speculation on whether or not this is safe to spread on the
vegetable garden?
How long before juglone is denatured?
