AsteraceaeCan you plant eggplant and lettuce together?
Yes. Eggplant and lettuce grow well together. A shared bed gave about 16% more harvest than separate beds in one field trial. That rests on a single study, so treat it as a lead, not a rule.
Why eggplant and lettuce work together
More harvest from the same bed. In one field trial, a bed with both crops gave about 16% more harvest than the same space split into a eggplant bed and a lettuce bed.

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).
