Question

Will cantaloupe be safe to eat if grown by a castor bean/ricin plant?

Answer 1

I would think so, as the roots of each plant will look for soil individually so one should not contaminate each other.  

Answer 2

I would post this on the Botany page under Science and Math, those folks are very helpful too.
