I would guess that there is no danger from the soil- but I don’t know for sure… I believe the toxic substance (ricin) is manufactured by the plant as an insecticide rather than an herbicide. The toxins produced to inhibit plant growth (allelopathy) are those that end up in the soil.

Quotes

  • A garden without a gardener is a jungle waiting to happen. A gardener without a garden is likewise a sorry sight indeed.
    —Margaret Roach
