Walnuts? What kind of walnuts? Black walnuts?

You seem like the kind of guy who would already know about walnut trees
inhibiting the growth of other plants. Grass seems to grow under a
walnut tree but many other plants are doomed if grown too near to a
walnut tree.

Speaking of worms, I remember when I was a teenager and I gathered a
bucket full of black walnuts from a tree near our property line. I
dumped them on the lawn and stepped on them to break open the outer
husks. Then I tried to clean them up with the garden hose. The water
mixing with the husks produced an inky dark solution like very black
coffee. The earth worms just about flew out of the ground! They weren't
going to stay under ground if that chemical concoction was down there.

OK, I don't have any great wisdom to share. I'm not sure how much of the
plant inhibiting substance actually comes from the leaves. (Well, I'm
not that clueless, the toxin juglone is what causes the trouble.) I
think I would be careful about composting black walnut leaves for use
where I plan to grow tomatoes or their relatives since they are quite
susceptible. I'm also not sure if earth worms would be repelled by the
leaves as they are by the walnut husks.

You didn't even specify black walnut so maybe I'm discussing this for
nothing. I guess I'm just having a burst of chattiness today.

Steve in the Adirondacks where there isn't a walnut tree anywhere near
here. (I grew up in Ohio)
