Should white onions bloom?
I am growing yellow, white, and green onions for the first time. I planted white and yellow sets in March, and they seem to be doing very nicely. But today I see that one of the white onions has a bulb thing on the top - I guess it wants to bloom?
We just had a big heatwave in the upper 90's here in the NE - 20 degrees hotter than usual for June. Did that make the onion "bolt"? Should I cut it off? Let it bloom?
What signs am I looking for to know when to harvest my onions?
