SolanaceaeCan you plant dill and tomatoes together?
It depends. Nobody has tested dill with tomatoes, as far as we could find. Garden charts disagree about it.
Why we can't give a firm answer
Garden charts disagree. 1 chart entry recommends the pair and 1 advises against it. 1 of them cite no source. Charts pass on gardening tradition; they are not tests.

Harvest from the same space compares a bed with both crops against the same area split into single-crop beds, counting the harvest of both crops (the land equivalent ratio in yield trials).
