Companion plants mutually benefit each other by providing protection from insects, enhance the flavor of the fruits. i.e. tomatoes and basil. Marigold is another example of companion plants. Marigolds protect from nematodes, Mexican bean beetles, squash bugs, trips, tomato horn worms and much much more.

I always place (1) marigold plant inside my raised bed. You must be careful with marigolds in The Tuxedo Garden. Marigolds plants will grow huge if you don’t manage them. The issue of over growing applies to a variety of herbs and other companion plants.
