Answer: I've heard that tomatoes love garlic. I think that the success of companion planting is based mostly on the fact that companions need to have the same cultural requirements - like lots of sunshine or very little water. Marigolds have a reputation forattracting slugs and snails, and Nasturtiums seem to attract black aphids. So, rather than thinking of them as companion plants, think of them as trap plants. If spider mites are attracted to your Marigolds, they may very well leave your tomato plants alone.
