If bunching onions are planted in fall, when do they make bulbs and when do they multiply at their base?

Does this all happen in the first growing season?

I am in north Texas, I am assuming I plant them in fall. The bulbing onion seeds are planted in mid October here, from what I read. Would it be the same for bunching onions?

I plant my carrots and such about sept 1-15.

I guess this is the same question but when can you pull them to eat, and do you just immediately replant a few for next year. Should it be the small or large bulbs. Our soil never freezes here.

When separating bunches of onions, to replant, what time of year should this happen?

Hawk, you need to differentiate bunching onions from multipliers or shallots. Many of the "bunching" onions are single bulb onions. Multipliers /shallots form a cluster of bulbs. In dealing with the multipliers they are harvested when the tops fall over and die for mature onions. The small ones are saved as sets for the next planting. Bunching onions are used almost exclusively as "green" onions. The bulbing onions that we use in the south are short day onions, meaning that bulbing is triggered by as little as 10 hours of daylight. Long day onions take about 16 hours of daylight to bulb. I am not aware of any short day bunching or multiplier onions, But since they are generally used as green onions, it probably does not make a lot of difference. For regular onions it means the difference between March/April harvest and July harvest. They will all live through our winters so you can use either fall or late winter (February) planting.

I have not grown Evergreen, but it is a very popular scallion and quick to make green onions. http://www.denverplants.com/veg/html/alliu_cep.htm While this site offers the standard " sow one month before last frost date" this type of onion is popular as as an overwintering onion in England. So I would expect a fall planting would work for you. It is a single stalk onion, not a multiplier. They take approximately 75 days from emergence to table. Of course winter growing is much slower.

Bunch actually means bulbless onions that that you pull and tie up in bunches for market. Alternate names are scallions or salad onions. Onions that divide into multiple stalks are multipliers/shallots/potato onions.

A lightbulb is going on over here as well... I've been wondering about those L'itoi onions I've got, and now I know.

Thanks, Farmerdill, for explaining the distinction!

orangehawkweed Hi!

There are some bunching onions that bunch. Or are supposed to bunch. This Fall I have planted all kinds of Onions, garlic and Leeks.
The Type of bunching onion I bought that I think will bunch is named "Hi Shi Ko". With true bunching onions, you leave a few so they can "bunch back up".
so now, in Central Georgia, in Oct 2010, The seeds are up and in the ground here. I also planted some in a long container. They look like they want to bunch! haha. Will keep you posted.

I live 8000ft in Colorado. My friend has bunching onions growing in his gound beds that survive winter lows of -20F. He has lots of mulching over them. He also is snug against a rather large and treed hillside. I did not think this was possible. I am making a raised bed, will they survive there also? I am in a more open housing development without trees and brush windbreaks.

You should care for them the same way your friend does and hope for the best. Even a bed on the south side of a house or shed is better off than no help at all. I suspect your friend actually has 'multiplying' onions, though- see above from Farmerdill explaining a true bunching onion.
