PoaceaeCan you plant celery and corn together?
Charts say no. Nobody has tested celery with corn, as far as we could find. None of the chart entries we found cites a source.
Why we can't give a firm answer
Garden charts advise against it. 2 garden chart entries say to keep them apart. None of them cites a source. Charts pass on gardening tradition; they are not tests.
