Not knowing that a companion planting specific forum existed, I posted this request for information in the vegetable gardening forum. The link to the discussion thus far that has not as yet yielded a why is below along with the text of the original question below that.

peppers and beans

I recently read to never plant peppers with beans while reading about companion planting. Can someone tell me why this is? I also want to find out how far away they should be and if this is all peppers (i.e. bell) or just hot peppers.
