SolanaceaeCan you plant cilantro and peppers together?
Yes. Cilantro and peppers grow well together. Cilantro kept pests off peppers in a field trial, and cilantro drew in insects that eat the pests of peppers in a field trial. That rests on two studies, so treat it as a lead, not a rule.
Why cilantro and peppers work together
Fewer pests. In a field trial, cilantro kept pests off peppers.

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).
