Companion Planting

Companion planting is the planting of different crops in proximity, on the theory that they assist each other in nutrient uptake, pest control, pollination, and other factors necessary to increasing crop productivity.

With this idea in mind I have planted garlic chives around my tomatoes and borage with my strawberries.  I just learned about the "three sisters" apparently the "three sisters" are the old ladies of companion planting.  I am also growing corn and plan to attempt a pole bean growing up the stock so I was almost there.
