In one yard, we have 2 aging Black Walnut trees. Every August
they start going dormant and lose their leaves. Grass, weeds,
vines, (all the undesirables) seem to grow just fine around the base
of these trees. I have a feeling that these trees are so old and the
soil so mounded up, their level of toxicity doesn't reach the surface
where most shallow roots grow.
Why anyone would want to do it I don't know but apparently some
people have tried using black walnut hulls for stable bedding and
found that horses absorb the poison through their feet. martha
