So this isn’t real scientific, however, I know plenty of University of MN horticulturists who DO use some of these “rules” for the vegetable garden.
There’s a book I recommend called “Carrots Love Tomatoes” by Louise Riotte. She also wrote a great article for Mother Earth News – “Companion Planting for the Healthy Garden” in 1992. It’s chock full of info!
Beth Jarvis with the U of MN was one of my instructors for the Master Gardener Program back in 2002. She compiled a list of companion plants as well. Click on the PDF: It’s quite extensive. CompanionPlantingGuideCompiledbyBethJarvis
