ApiaceaeCan you plant radishes and carrots together?
Charts say no. Nobody has tested radishes with carrots, as far as we could find. The chart entry we found cites no source.
Why we can't give a firm answer
Garden charts advise against it. 1 garden chart entry says to keep them apart. It cites no source. Charts pass on gardening tradition; they are not tests.
