I believe there is sound science in companion planting. The problem I am having is the variance of information from one site to another. An example is growing tomatoes near corn or dill. I have read that they should not be planted together, yet there is no reference to tomatoes near corn or dill here. I have found quite a few variances and at this point, I"m not sure how to lay out my garden. This year I'll be planting almost every type of veggie I can think of. Any thoughts/advice?

I know there is sound science to companion planting. The problem I am having is the information on this varies from one site to another. For example, in multiple other places I have read that tomatoes should not be planted near corn or dill, yet there is reference to that on this site. Any thoughts on this?

Myth? I doubt it. Plants are chemical production factories and do impact each other. I majored in plant science, and very little is known about plant chemical interactions, but each research paper adds a little bit. I have hardened fifty years, and mix plants all the time, use no pesticides. I did study the plant-soil interface, and quit using fertilizers, they kill soil microbial life. I tuck beans and peas arround everything. Interplant herbs with vegetables. Edge it all with onion, garlic, nasturtium, calendula. I plant nothing in rows. Polyculture is healthier than monoculture. I have lizard housing all around, they keep pests down. I have penstemons to bring in hummingbirds, which eat their weight in insects every day.
