Walnut/Black Walnut Leaves, Juglone, and Composting

A couple of autumns ago (in the northern hemisphere, just in case that matters), someone advised me to be very cautious about composting leaves I collected from the curbside, where homeowners in my community place them for collection by the city.  (I'm only collecting from my street, just so you now that, too.)  We have a number of walnut trees in several back yards on both sides of the street, and as you are probably aware, the juglone from walnuts (Persian or English/Californian walnuts) and from black walnuts has a powerfully toxic effect on a number of plants.

But, it happens, not on all.  There are some plants which are resistant to it.

In a conversation this past week, the subject of walnut or black walnut trees and the composting of (or mulching with) their leaves came up and of course so did the question of juglone toxicity.

For those who have had concerns about walnut or black walnut leaves in their compost and adverse effect on other plants by the juglone which is found in the leaves direct from the tree/s, here is what The Ohio State University extension has to say on the matter:
