Hi --
Years ago it was believed that crushed walnut shells poison the soil for
garden plants. Is this still the prevailing wisdom?
Have an abundance of shells from a gift box of walnuts received from CA.
Seems wrong to just toss in the garbage. Always thought what came from the
ground should be returned to the ground, but I don't want to hinder the growth
of my garden plants.
