First off I have not grown shallots, but grown garlic for several years.
Most long day alliums get their size when the days are getting longer. So trying to grow them in the winter will probably not produce a very large bulb.
Personally I would mulch heavily with straw. Then start more at the right time.

Agree with obrionusa. Your shallots probably won't bulb up this year but you can eat them at any time as green onions.

As for trying to get them through the winter, I wouldn't cover them with anything. Just put a thick layer of mulch down. They should make it through the winter and produce bulbs next year.

I grow shallots the same way as I do garlic. They are planted around the same time (in October) and are usually harvested around the same time (in July).

Thanks so much folks! Yeah, rookie mistake on my part....... Guess I'll mulch these & roll the dice!

To be perfectly honest, I purchased these sets from a local nursery thinking I was buying onion sets. It was only after I had planted them that I discovered I'd bought shallots.... Please humor me, I'm old........LOL

With severe winters (DOWN TO 0F), I think you can plant them in the earliest spring when the ground can be worked.

You should experiment different methods. Un less your County Ag specialist can give you an advice. OR learn it from the locals.

I agree with Sey.....Shallots are very tough perennials when well rooted, and your plants are. They can lose all their tops to cold or harvesting and will come back like gangbusters in the spring. I would mulch some to prevent topsoil loss over winter but not to insulate the roots. Hope for snow, they love it.

Thanks folks! I'm feeling a bit better about my rookie mistake...... ;) Harvesting the tops sounds like a great idea! Snow in NE Kansas is a pretty sure bet, so they should thrive....
