This is what someone told me that if you put marigolds near the tomato plants, they wont get the worms.

Do Marigolds stop Tomato Plants from getting tomato worms?
Planting marigolds and other aromatic herbs will prevent the tomato worms from going from one plant to another, since the smell puts them off.





However, to prevent the worms from getting to the tomatoes in the first place, place a "collar" around the base of the plant. You can make a collar from an old yogurt container, deli container, whatever, and simply slice the bottom off, then place over the plant so that it presses firmly against the ground. Not using pesticides in your garden will attract the beneficial bugs and birds that will help keep those pesky things under control.
Reply:Not that I have ever heard of. It has been said that planting Marigolds around your garden will stop rabbits but I have not found that to be true either.
