I would plant them in individual containers or one big one but separated by a bit of space, and put them under lights until they can go outside.

They are available here and of course may be planted in the garden immediately. With our long growing season and enough sun and water they will make good sized onions by the fall. In your location you will have to plant them twice as oilpainter has suggested. Al

I have heard that I can plant them outside right now, I think. Will they be able to withstand a frost? I just don't have the room to transplant that many onions.

Do you know the type - long-day or short-day? Hopefully they would only sell long day types in your area but no guarantees. Still long-day types is what you should be growing. If you are getting 10-12 hours of daylight by now then they can be planted.

Dixondale Farms (noted plant supplier) recommends that if they can be planted within 2 weeks of arrival/purchase you don't do anything to them except keep them cool and dry. These are dormant as is so will do fine as it. Down here they went to the garden a month ago as soon as we hit 10 hours of daylight because we have to grow short-day varieties.

Yeah, we are definately getting 10 to 12 hours of daylight here. So that's good.

Oh! But I almost forgot. Do I need to harden these off? And if so, for how long? It's going to be cold the next day or so, and then it is supposed to jump back up to the high 50s low 60s. I had planned on planting them on Tuesday, but I may need to wait if they need time to adjust.

Thanks so much! Kim

No they are dormant plants. Dormant plants don't need to be hardened off.

Dave

Sweet! Because I am really looking forward to it. :)
