Good companions for broccoli

No sourced companion pairings for broccoli yet.

Use caution

  • Cabbage

    Extension guidance

    Broccoli and cabbage share pests and diseases.

    Both are Brassica oleracea cole crops with similar cultural requirements, diseases and pests. Grouping them gives those pests more to feed on, and cole crops should not follow each other in the same spot.

    Spacing: No safe separation distance is established; rotate cole crops to a new spot each year.

    Pests: Scout for caterpillars and flea beetles; row covers can exclude them.
