what plants go where?

what plants go where?

Does anyone out there have knowledge about conflicts between plants? I'm looking at re-doing my garden a bit for this year. I have a bed that has strawberries in it right now - that's going to come out, the slugs were just not worth fighting for the miniscule harvest you get in Texas. I'm thinking about planting either peppers or tomatoes there, and on the other side of the fence, where I had gomphrena (globe amaranth) last year. I know tomatoes are clear to replant in the same spot year after year as long as there's no major disease. I assume that carries over to chili peppers. What about mustard greens and cantaloupe? Sunflowers don't much care, I expect, either. What about radishes? Some book I read at some point had this information in it, but finding it on the web seems a bit pesky, unless you're talking about straight companion planting.
