I live in central Michigan, zone 4/5 border. They would grow great in southern Minnesota. you won't want to plant brassicas till around July 20th, they mature quickly. this plot was planted on august 1st. they key to good brassicas is to get soil test and add the neccessary lime and then put on 300 pounds to the acre (6 bags per acre or 3 bags per half acre) of 19-19-19. they grow fast and require lots of fertilizer. if you have any questions don't be afraid to ask.
