I tried to grow cauliflowers last year for the first time but not with much much success, they were growing OK and started to produce heads but then they blew/ went to seed? I put winter ones in (not in the same area) last Sept/Oct they have grown over winter OK but I'm still waiting for heads to come and we are into April? anybody any ideas to the problem/s. am growing all year round from seed this time have started some off in modules to to get a early start. all help welcome compo. :-\
