Why are my onion sets going to seed?
AIt’s common for onions to bolt (run to seed suddenly) when there is a cold snap – it’s as if the plant thinks winter is setting in and quickly throws out some seeds. They can also bolt in very hot weather – they get dry, panic and run to seed. Onions are temperamental and susceptible to changes in their environment.
