Companion Plants for Mint
Traditional companions for mint include broccoli, Brussels sprouts, cabbage, cauliflower, cherry tomatoes, collard greens and 7 more in the table below.
These are garden traditions, collected from 13 US extension guides. Few have been tested in trials, so treat them as a starting point: spacing, sun and rotation matter more.

What the evidence says
Companion planting charts come from long garden experience, and most pairs have never been tried in a replicated trial. Several extension services say so directly; one review gives traditional charts more entertainment than scientific value.
What reliably helps mint: the right planting dates, enough space, and moving crops to a new bed each year (crop rotation).

Questions
What can I plant with mint?
The traditional companions are broccoli, Brussels sprouts, cabbage, cauliflower, cherry tomatoes, collard greens, head lettuce, kale and 5 more listed above. Plant companions in neighbouring rows or squares rather than in the same hole.
Does companion planting with mint work?
Most pairings are tradition rather than tested results: extension services call companion planting promising but largely unproven. None of the pairs for this crop has been tested in a trial we could find. Good spacing, sun, water and rotation do more for a harvest than any single pairing.
How close can broccoli grow to mint?
In a raised bed planted by the square foot, give mint 1 per sq ft and broccoli 1 per sq ft, in neighbouring squares. In rows, mint needs 18 in between plants.
