Best Roommates 12

Carrot

Different root depths—carrots go deep, eggplant medium. Loose soil from carrot cultivation helps eggplant root development.

Tomato

Fellow nightshades with identical growing requirements—sun, warmth, water schedules. They share beneficial insect attraction and don't compete for root space.

Pepper

Another warmth-loving nightshade with complementary pest resistance. Basil benefits both eggplant and pepper equally, creating a triumvirate of summer production.

Basil

Basil's aromatic oils repel flea beetles and spider mites that target eggplant; they're also nightshade neighbors with similar water needs and both thrive in warmth.

Chives

Chives deter spider mites and whiteflies with onion-family pungency. Perennial chives can be planted near eggplant without replanting annually.

Garlic

Garlic's sulfur compounds deter spider mites and whiteflies. Spring-planted garlic is harvested before eggplant matures, avoiding competition.

Onion

Strong pungent compounds confuse and repel flea beetles and spider mites. Onion's shallow roots don't compete with eggplant's medium-depth root system.

Marigold

Bright marigolds attract beneficial predatory insects and may deter flea beetles. They also add visual appeal and are edible.

Spinach

Quick-harvest spinach uses space before eggplant's canopy expands. Its shallow roots cause no competition while providing living mulch benefits.

Oregano

Oregano repels beetles and spider mites with aromatic compounds. It also attracts hoverflies whose larvae consume aphids that bother eggplant.

Parsley

Parsley attracts beneficial parasitic wasps and hoverflies. Its upright growth doesn't compete with eggplant for light.

Thyme

Low-growing thyme attracts beneficial wasps that parasitize hornworms. It won't shade eggplant and improves soil with its decay.

Keep Your Distance 4

Fennel

Fennel produces allelopathic compounds that inhibit growth in nearby plants. It specifically stunts nightshade development—avoid fennel entirely.

Potato

Both are nightshades with identical pests and diseases. Planting them together creates a perfect storm for Verticillium wilt and blight spread.

Kohlrabi

Another brassica heavy feeder that competes aggressively for nutrients. Disease problems can overlap with eggplant.

Cabbage

Heavy nutrient feeders that compete with eggplant for nitrogen and potassium. They also attract overlapping pest populations.
