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

Helps

  • Tomatoes Traditional pairing1

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

  • Lettuce Traditional pairing1

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

  • Carrots Traditional pairing1

    The chart says "onion family"; garlic is an onion-family (Allium) crop. The carrot fly study tested onions, not garlic.

Keep apart

  • Beans Traditional pairing1

  • Peas Traditional pairing1

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

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.
