Can you plant cilantro and corn together?

Yes. Cilantro and corn grow well together. A shared bed gave about 42% 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 cilantro and corn work together

More harvest from the same bed. In one field trial, a bed with both crops gave about 42% more harvest than the same space split into a cilantro bed and a sweet corn 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).
