Hi all - This year was my inaugural year of planting a winter garden. However, I've lost all of my winter cauliflower (a variety obtained via West Coast Seeds, I believe) as the heads (which were fine up until they were about 8-10 centimeters across) have turned brown and rotted. Is this a case of the soil they're in being too wet? Or has it just been too wet in terms of rainfall this winter? Any advice would be appreciated!
