Seems prone to disease.

I sowed and planted Red Baron in addition to the Bedfordshire Champion onions and, whilst there is some sign of trouble on the Red Baron, it is far less so than on the Bedfordshire Champ. I’ve attached a photo of the BC; is this downy mildew/ neck rot disease? If so, I’ll try Santero next year instead.

Thanks for your advice, we shall eat what can be saved. I hope yours grow well and through to maturity!
