Companion planting is the practice of planting two different plants in close proximity to each other on the theory that they may help each other in some way. Some plants complement each other, giving off byproducts that the other plant needs. Those byproducts may be chemicals and micronutrients that the other plant may benefit from.

Other beneficial plants provide some protection against insects and planting a few of them near a desired plant may help to keep certain insects away. For example, I always plant some marigolds in amongst my pepper plants. This helps repel aphids from my plants and it kind of looks pretty as well. The bright splashes of color are fun amongst the green.

Here is a list of vegetables that you may plant or have planted in your garden and what goes well together and what does not:
