Early potatoes - wilja

I ordered some wilja second earlies last Sunday. I thought I would get in early as there is only one online shop in Belgium selling this variety. The site also warned it might take longer than usual to deliver goods owing to the current huge demand  (last year it took a month for my potatoes to arrive!).

Anyhow, they arrived today. A bit early. Will they keep until early March (which I supppose is the earliest I can plant them)? And what are the best storage conditions? Thanks in advance?

Thanks Mumofstig. And the earliest for planting?

Thanks. I hope these potatoes will keep until March!

Thanks for the reassurance Yorkie.
