Tomato Guild

Strategic companions that protect tomatoes and improve harvests

Summer Intermediate

Everything a tomato plant needs to thrive. Basil repels the destructive tomato hornworm and improves flavor, marigolds deter nematodes and other pests, and carrots with their deep taproot don't compete with tomato's root system. Multiple defenses, complementary growing needs.
