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? Ross. Southern Ontario, Canada. |

How long before juglone is denatured? i think it is a component of the material, so more would become available as the material degrades. i'd not risk it. spreading it very thin on the lawn or a wild field or using it as a pathway mulch for raised beds would be two uses for it. keeping mud down in a dirt drive during the wet season... hmm... bury it and build a new shed over it? ;) songbird |
