John, The area of 'why' is a wonderful addition but still ventures into the folklore perception. Most of the on-line charts show the why. There are a few sites that offer plants in answer to a problem. The latter sources are likely how you generated your chart and the effort is appreciated. The companion plant relationships are one area of personal study. My goal is finding actual facts offering the biological, chemical and/or ecological contribution. Some of the obvious are know symbiotics. I have posted a few links in Organic and Vegetable topics that have been looked at. It is very hard to locate specific relationship studies and suppose that there are few actual such studies. One item of note is the marigold action against nematodes. In report I have view they credit the exudates but after residue is incorporated and decomposing. The effect is generally of advantage in the following year of the incorporation. Food for thought and example of the information I hope to provide in such a chart. Good effort. Thanks.

byrd2park where's your garden plan? Interesting to hear how others plan or don't plan your gardens. My garden was once much bigger, and I tried a lot of different things, but I've simplified it. I change it up a bit year to year, like last year I grew corn. It's a soaker hose layout, using some plastic and then mulch in between the rows. 2017 Back row of sunflowers Trellis for cukes and green beans 8 tomatoes 3 peppers and 2 summer squash An area for the sprawlers, Delicata and Spaghetti Squash, along with ornamental mini pumpkins (for fall decorating). Tomatillos to make and freeze some more salsa verde And a row of Zinnias across the front, which is along the street. Zowie this year. I grow snow peas and herbs in pots on my deck.
