Onions from Seed in Zone 6

I've read a lot of conflicting info on when to start my onion seeds in zone 6. I've come up with this and am looking for your thoughts. The kinds I have are:
Tropeanda Tonda
Yellow Borettana
Dorata di Parma

The plan is to sow thickly in 3x3 co. on 2-15. Diluted fish fert every 2x. not to thin. cut back leaves to 3" every two weeks. Plant out as transplants on 4-15.

Does this timing sound right?
Unrelated question; can you chop and freeze onions right away or do you have to wait the 3-4 months to cure before chopping and freezing?

Thanks for the info.

PS I did great concentrating on my peppers last year because of all your good advice. Next year -- onions!!

I mean two to three weeks to cure.

Other than Yellow Borettana which I know is a long-day variety I would have to look up each of those varieties to find out if they are short day or long day or intermediate day length varieties - onions are day length sensitive and that determines which type you can grow and when they are planted. So without that info this is just general info.

Would also help to know where in zone 6 you are located to know which types you should be using.

In my part of zone 6b we use only short day varieties and they are started from seed in early December and transplanted to the garden in late January - to early February.

If you haven't already done so I'd suggest you go to and review some of their detailed info on growing onions and learn which types you should grow and when to plant.

'Cut back leaves to 3". Plant out as transplants on 4-15.'

I have not researched the type of onions you are planting, however...

I think you could put them out sooner than that. I live in central Indiana and usually plant onions by mid-April. 2012 was so strange and mild, they went out the first half of March and did great. We just got changed from zone5 to zone6.

3" sounds a little short to me. This past year, I pruned mine to about 6" tall because the wouldn't fit in the old fish aquarium I was using as a mini greenhouse. I use old "lunch meat" tubs wrapped with duck tape to keep light out and drilled some drain holes for starting the seeds. I got about 70 onions per tub.
