Companion planting probably began when early gardeners noticed that some plants seemed to grow best when planted next to certain other plants. There is some science to back up this lore, but many still consider companion planting to be mostly unproven.
Of course, gardeners can always try it to see if it works!

Research into companion planting folklore shows that there are, in fact, naturally occurring compounds in plants that act as pest repellents, or that attract predators of pests.
COMPANION PLANTS
Companion plants are used to confuse or repel plant pests, to encourage the growth of other plants and to act as a trap for pests and parasites. "Trap" crops draw harmful insects away from the plants you are trying to grow.

Companion plants may also be used a a "nurse" crop--to provide food or possibly an attractive home or habitat for beneficial insects.

Companion plants may produce odors that confuse and deter pests, or their scent may mask or hide a crop from pests.

The table below lists some commonly held beliefs about the uses of companion plants.
