Flowers such as marigolds and nasturtiums are very beneficial to vegetables such as tomatoes and cucumbers, because they help to repel a large variety of destructive pests. Marigolds repel nematodes, whiteflies, Mexican bean beetles, and tomato hornworms. Nasturtiums repel aphids, pumpkin beetles, squash beetles, cabbage moths, potato beetles, and whiteflies. Herbs such as onions, chives and mint help to repel aphids and nematodes. Beans and legumes help to bring nitrogen to the soil, which fertilizes all plants.
