Question: I see tags on some tomato plants that say, "plant with basil," does that mean plant in the same hole, within 6", or just the general area? Also just what good does it do? -Ed
Basil is a great partner for tomatoes. It not only enhances the flavor of tomatoes, it also repels aphids, whiteflies, hornworms, mosquitoes and other insects. The art of planting different plants together for their mutual benefit is called companion planting. By planting complimentary plants next to each other, you can intensify the flavor of vegetables, enrich the soil, attract beneficial insects and repel pests. Just plant basil next to your tomatoes (6 inches to 12 inches) in the same garden or container to see the results. And try some of these other companion plants, too!
