Can you plant beets and cucumbers together?

Charts say yes. Nobody has tested beets with cucumbers, as far as we could find. The chart entry we found cites no source.

Why we can't give a firm answer

Garden charts recommend it. 1 garden chart entry recommends growing them together. It cites no source. Charts pass on gardening tradition; they are not tests.
