What to plant with peas

Sources list Beans, Carrots and Cucumbers as good companions for peas. Keep peas apart from Onions, Garlic and Potatoes. None of these pairings has been tested in a study we found.

Good neighbors first, then plants to keep apart. Each one says how strong the evidence is.

  • Beans Traditional pairing1

  • Carrots Traditional pairing1

  • Cucumbers Traditional pairing1

Keep apart

  • Onions Traditional pairing1

  • Garlic Traditional pairing1

    The chart says "onion family"; garlic is an onion-family (Allium) crop.

  • Potatoes Traditional pairing1

Traditional pairings come from a UC Master Gardener chart that traces to the UC Davis Edible Landscaping Handbook and ATTRA. The chart gives no reasons, and we found no trial of these pairs; treat them as garden lore.
