Companion Planting Charts

Introduction to Companion Planting Charts:

Companion planting is a rather simple concept where you find plants that are mutually beneficial to one another, and then you plant them in the garden side by side. The end result, if you have chosen the right combination of plants, is both plants will not only thrive in this situation, but you should also see much better performance than if both were planted separately in their own space.

There is a wealth of information out there on companion planting charts but in my own research I realized that much of it is jumbled and difficult to read and understand. Since we have discussed companion planting so often in various articles on this site, I decided I should probably take some time and compile information that I've seen scattered about, and hopefully in the end make it a little more intuitive and user-friendly. The following lists are by no means definitive as the technique of companion planting charts is ever-evolving and gardeners are always coming up with new combinations.
