Tomato Companion Planting

Companion planting can improve tomato yield, deter pests, and enhance flavor. Here are the best and worst companions.

Best Companions

• Basil: Repels aphids, improves flavor (claimed). Plant 12-18 inches away.
• Marigolds: Repel nematodes and aphids. Plant around the perimeter.
• Carrots: Break up soil near tomato roots. Plant between rows.
• Borage: Repels hornworms, attracts beneficial insects.
• Parsley: Attracts predatory insects that eat tomato pests.

Plants to Avoid

• Fennel: Inhibits tomato growth. Keep well away.
• Brassicas (cabbage, broccoli): Compete for nutrients.
• Corn: Attracts same pests (earworm/fruitworm).
• Potatoes: Same diseases, spread easily between the two.
