AsteraceaeCan you plant garlic and lettuce together?
Charts say yes. Nobody has tested garlic with lettuce, 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.
