Some vegetables defend themselves when grown in the right company.
These 9 pairings create natural pest barriers without a single spray.
- Tomatoes & Basil: Basil's methyl eugenol repels thrips and whiteflies from tomato foliage within a 2-foot radius
- Tomatoes & Marigolds: French marigold roots release alpha-terthienyl, killing root-knot nematodes in the surrounding soil
- Peppers & Nasturtiums: Nasturtiums act as a trap crop — aphids attack them first, sparing pepper plants entirely
- Carrots & Rosemary: Rosemary's volatile oils mask carrot scent from carrot rust flies during their May egg-laying window
- Cabbage & Dill: Dill flowers attract parasitic wasps that lay eggs inside cabbageworm caterpillars
- Squash & Radishes: Radishes planted around squash hills lure flea beetles away from squash seedlings
- Beans & Savory: Summer savory repels bean beetles while enhancing bean flavor through root proximity
- Eggplant & Catnip: Catnip releases nepetalactone, a compound 10 times more effective than DEET against flea beetles
- Cucumbers & Tansy: Tansy attracts ladybugs that consume cucumber beetles at a rate of 50 per day
Plant allies, not chemicals.
