Hi Galina, I have planted my seed potatoes in the fall (I think this is what you are asking). I mostly grow mid to late varieties for storage. Mulched and they did fine. Except one year mice had a field day all winter with the ready food and ate about half of them so I went back to spring planting. Potatoes that I miss when digging grow up just fine the next year without any mulch or bother. As long as they don’t freeze they’ll grow. If the volunteers are not in the way I let them grow, but usually try to weed them out.
I also plant twice in the spring, some early May (which I often have to cover because of frosts) and then my main crop the end of May so I don’t have to worry so much about late frosts. Different years one or the other does better but it all depends. I’m in a colder spot so my planting window is probably smaller (to make sure they mature before fall).
For me, the tubers keep just fine in the ground until I want to dig them in October, even if the plants die from frost blight in august. Sue
