Ive grown onions for years with no problem but since moving to Hungary im having big prolems. Firstly I get alot that bolt but my biggest problem is why do they split. By that I mean when I go to peel them theres 2 onions under the skin and where they join each has a flat side which then means they are quite small. Im sure last year I grew stuttgart (not alot of choice here) and from May to August its extremly hot 75 to 100.
