LamiaceaeCan you plant lettuce and mint together?
Yes. Lettuce and mint grow well together. Chemicals given off by mint helped lettuce in a greenhouse or pot trial. That rests on a single study, so treat it as a lead, not a rule.
Why lettuce and mint work together
Helpful plant chemistry. In a greenhouse or pot trial, chemicals given off by mint helped lettuce.
Spearmint enhances lettuce biomass and provides microbes to co-cultured lettuce in a decoupled aquaponic system (Atique F · 2024 · Research Square)

Companion plants for both lettuce and mint
Plants that are good neighbours of each. Biggest harvest gain first; each cell links to the evidence for that pair.

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).
