Ive planted them amongst my vegetables on a friends advice.

Is it true, that marigolds act as a natural pest deterent?
This technique takes advantage of the various ways different plants complement or protect one another, thereby promoting each others' healthy growth. Marigolds, for example, have a natural resistance to insects, and planting marigolds as a border around the garden, or among vegetables, seems to discourage both insect and animal pests in colorful fashion.
Reply:Yes, it's the smell that they don't like.
Reply:I`ve heard that deer %26amp;rabbits don`t like them.
Reply:Well, there is some benefit to interplanting them with tomatoes - but Marigolds ATTRACT earwigs, which eat all the foliage off the flowers and creep me out no end. I have never noticed any real deterrent effect.
Reply:yes it's true. however, next time, you may want to place pots of them in the garden. i think you'll find that they expand quite a bit. i once planted about a dozen plants in a 15 foot border and they completely filled it in. pots contain them better
Reply:I know my mother use to use them in her flower and vegetable garden to attract bees for pollination.
Reply:Marigolds are a great companion plant for tomatoes!


Marigolds put out an oil similar to tannin that deters Nematodes, a tiny little worm that eat root hairs.


If there are enough of them in your garden soil the Nematodes will cause stunted growth and yellowing of leaves.


Nematodes can build up in the soil over the years and can be found in lawns as well.

The aroma of Marigolds is supposed to bother a few other insects but I've seen no proof of this yet.
