How much longer?

[Ms. Jitomate]

I planted onions--Yellow Rock and Red Wetherfield-- and I want to know how much longer do they have to stay in the raised bed? I planted on Oct/12/13 and some have had a flower stalk start to form. I cut it out. They are not looking good, some have brown tips, but none are showing any onion at the surface. I fertilized in the beginning by adding organic fertilizers in the soil and in late April I had extra liquid fertilizers that I added twice that month. What did I do wrong?
