I think it depends on how cold they'll get in the shed. If they can be protected from the freeze/thaw/repeat cycle they should do fine. I've seen posts where people have stored them in attached garages and basements successfully. It's a fine balance--too little cold and they won't bloom next spring, too much and the roots won't make it. I avoid putting them in pots because I'm not reliable about putting them somewhere protected, all that I've left outside have died in pots.

Thanks. I will probably put them in the unused part of the basement to be safe.

If your ground isn't frozen yet, plant them.

I agree with graycrna4u. Peony roots this time of year are completely dormant, you're not going to harm them with planting them this late. If it's doable to get out there and dig that would be the best solution. I've read this same advice from several of the big growers as well. You don't have to water them when planting, just tamp the soil down really well and they'll be good until they wake up in spring.

I agree, plant them if you can, keeping them in your basement is too warm.

Okay, I will plant in a temp location. They do seem have a few eyes growing, hopefully they won't be affected with the transplanting.
