Hi Annette, I went through this last year, but planted directly, so situation is different. I am pretty sure it is better to get rid of foliage right away and if you can not find pots big enough for the roots - cut them to the size. I am not big fan of overwintering any plants in pots as they generally do not survive for me here in Toronto. I think planting and covering in soil is better, even if you have to move them again next year. How many plants we are talking about? May be those tree soft-side bags are better if there is enough soil there. Finding a secure spot in new constructed home yard is something to consider. Then move them to the right space in a year or two.
