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
