Best Companion Planting Combinations for Veggies

What Is Companion Planting?

Companion planting grows certain plants near each other for mutual benefit. Benefits include pest deterrence, improved flavor, better growth, and efficient space use.

Tomato Companions

Plant basil, carrots, and marigolds near tomatoes. Basil repels aphids and hornworms while enhancing tomato flavor. Marigolds deter nematodes.

Bean Companions

Beans fix nitrogen in soil, benefiting neighboring plants. Plant them with corn, cucumbers, and radishes. The Three Sisters method combines beans, corn, and squash.

Lettuce Companions

Lettuce grows well under taller plants that provide partial shade. Plant near carrots, radishes, strawberries, and chives. Chives deter aphids.

Pepper Companions

Peppers thrive near basil, onions, and spinach. Basil deters aphids and spider mites. Avoid planting peppers near fennel or kohlrabi.

Plants to Keep Apart

Keep beans away from onions and garlic. Tomatoes and potatoes should not share beds. Dill stunts carrot growth but attracts beneficial insects elsewhere.

• Rotate companion combinations each season
• Observe which pairings work in your garden
• Use trap crops like nasturtiums to lure pests away
• Companion planting supplements but does not replace proper care
