From observation, anything outside the dripline is usually safe, as long as the leaves aren’t used as mulch, of course. The leaves don’t have much of that chemical in them, but enough of them piled on can have an effect.

We are fortunate to have 3 or 4 black walnuts in a tree line on our farming ground, so not putting them on the homestead acreage works.

Wish I could remember exactly what that elderly man told me. He's gone now and I can't ask him. :(
