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 Brussels sprouts: the right planting dates, enough space, and moving crops to a new bed each year (crop rotation).

Questions

What can I plant with Brussels sprouts?

The traditional companions are beets, bush beans, celery, chamomile, chives, cucumbers, edamame, fava beans and 18 more listed above. Plant companions in neighbouring rows or squares rather than in the same hole.

What should not be planted with Brussels sprouts?

The guides keep cherry tomatoes, strawberries and tomatoes apart from Brussels sprouts. Give them a different bed.

Does companion planting with Brussels sprouts 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 chamomile grow to Brussels sprouts?

In a raised bed planted by the square foot, give Brussels sprouts 1 per sq ft and chamomile 4 per sq ft, in neighbouring squares. In rows, Brussels sprouts need 20 in between plants.
