Eggplant

Tomato

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

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.

Carrot

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

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.

Pepper

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

Spinach

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

Garlic

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