What to plant with cauliflower, a vegetable with a reputation for being somewhat fussy and difficult? Cauliflower is traditionally planted with beans, peas, spinach, and celery. It may benefit from being planted near herbs such as sage, dill, and chamomile.
GardenZeus expert Darren Butler generally disagrees with most claims about usefulness of companion planting with cauliflower and brassicas and recommends planting cauliflower and other brassicas away from the rest of your vegetables and other plants. Micorrhizal fungi may capable of “stealing” nutrients such as nitrogen from brassicas to share them with their host plants. Darren has often found that many mysterious issues with stunting, heading, and plant health for broccoli, cauliflower, and other brassicas go away when the plants are isolated at a distance of several feet or more from other plants.
